Check if you can boot into recovery mode (selecteable in grub menu).
This will launch the system in text-only mode.
Try to login.
Once loged in, reinstall the lightdm packages with:

sudo apt-get purge lightdm (this will remove it)

sudo apt-get autoremove (this will autoremove leftovers)

sudo apt-get install lightdm (this will install it again)

Reboot, cross your fingers and hope you will se your default login screen again.

I have the same problem with my Elementary, but I cannot login to recovery mode and have to find another way to reinstall the lightdm.


Broadcom drivers reported to broke for many users after the kernel update.

Take a look at this post: BCM43142 and linux kernel 4.15.0-24-generic


Can't update Agenda anymore because of minimum price. - Where i live Credit Cards are unpopular and i also don't care to get one

Though this won't exactly solve your problem, you might want to check out a prepaid credit card for these purposes. Sharing your background (being a German myself and so far lacking a credit card as well) I've been through this a couple of times already. Statement so far was that elementary essentially relies upon stripe.com for handling payments and so is limited to supporting payment methods supported by stripe. Maybe you might want to add yourself to feature requests in the relevant github repo, especially

add the following line to the options section

options snd-hda-intel dmic_detect=0

cd onto

Installation on flash drive produces errors. Did I install correctly?

I have the Razer Blade Stealth too and have the same issue with the garbled screen and crashing - Elementary crashing on desktop login

In my case I've installed it to the internal SSD so it isn't due to you using a flash drive as I have the same issue.

The reason you're having to run fsck is the filesystem was marked dirty due to the crash - if you use a journaled FS (like ext3/4) you probably won't get that error as it will repair itself from the journal after a crash. This won't fix the crashing though!


I deleted my /boot folder and it's strange but now elementary OS doesn't boot anymore

See this link. It contains the solution. https://www.howtogeek.com/114884/how-to-repair-grub2-when-ubuntu-wont-boot/


Try installing the GPG key

$ wget -q "http://packages.elementary.io/key.asc" -O- | sudo apt-key add -

, then

$ sudo apt update


Changing desktop background should also change the login picture?

Related answer: here.

The answer to my question is YES: the login image should also change just by selecting one of the images in /usr/share/backgrounds from System Settings -Desktop - Wallpaper.

In fact there is a bug where the login picture cannot be changed:

https://bugs.launchpad.net/elementaryos/+bug/1391716

also:

https://bugs.launchpad.net/pantheon-greeter/+bug/1324373

In this case the new images copied into usr/share/backgroounds may not even be seen from System Settings -Desktop - Wallpaper.

To fix this:

Open Files as administrator
Select the image file in /usr/share/backgrounds and open its Properties (if you want a new one copy it there first)
Change permissions to 644

Use System Settings -Desktop - Wallpaper as normal


Try reloading the driver by running:

sudo modprobe -v ath9k


Try to disable IPv6 and restart system. Few Ubuntu distro had similar issue in back., Since eOS is based on Ubuntu worth trying if that'll fix issue.


Try right-clicking on the windows title bar and selecting "Always on visible workspace"


This issue has already been reported to the eOS devs. However, you may want to provide your details there too.


try this in terminal: sudo modprobe snd-hda-intel, if you recover audio, add snd-hda-intel to file /etc/modules. This will make the snd-hda-intel module load up  at boot time.

You can use: sudo sh -c 'echo "snd-hda-intel" >> /etc/modules' to do this


I finally find out how to correct this and I will leave it here for future reference for those who might be having similar issues.
I just followed the answer posted here https://askubuntu.com/questions/455888/low-resolution-on-lubuntu-14-04-sis

EndSection

And that's all. Reboot, and you should have your resolution."


Issue installing elementary on Sony Vaio laptop

This is likely caused by a "secure boot" UEFI flag in your BIOS. You'll need to reboot and press the key on your laptop to enter the BIOS (probably F2). From there, you should be able to find an option like "secure boot" and disable it.

Alternatively, if you want to update your question with exact details about your model, someone might know more specifically what you need to do.


Elementary OS freezes while watching Video or when connecting to a SMB server

I managed to solve the problem by disabling the USB 3.0 support in the notebook's BIOS.

Note: This also made the "quite splash" edit obsolete.


I fixed it!
First, I tried to reinstall elementary os from my USB stick - didn't work. The USB stick stopped working too.
Then I download OpenSuse in another USB stick. It worked on trial mode but it didn't find any directory on my computer. Therefore, it did not install anything on my computer.
Then I tried to install Manjaro. It didn't work, but a new message started to show on my screen about a bug in BIOS and initramfs. (before there was a message about no directory found). This was the turning point for me to fix it. Unfortunately, I don't know how it happened.
After, I followed this: https://www.youtube.com/watch?v=xf
Basically, you need to type: fsck /dev/sda1
It didn't work with sda1, so it tried with sda2. It worked!!
I followed the rest of the video (just type yes for everything). Then, type reboot. Then select the option *elementary, and that was it. My Notebook started to work again as it was before. Elementary was working as if anything has happened. I did not lose any of my packages.
I don't know what or how it happened but it worked. Above is exactly what I did. Probably most of it has nothing to do with the solution.
One more thing. The problem started after I tried to updated my elementary os. I did not try to update again.


Backward Rotation Settings for Tablet Mode of Asus TP200S

Solution

This was an issue with iio-sensor-proxy. Running "monitor-sensor" in terminal showed an incorrect orientation, so I knew the problem was with iio-sensor-proxy and not with Elementary OS.

Sudo all steps.

Navigate to /lib/udev/hwdb.d and open 60-sensor.hwdb with a text editor. Scroll down to where you start seeing entries that look like the following

sensor:modalias:acpi:INVN6500*:dmi:svnASUSTeK:pnT100CHI

ACCEL_MOUNT_MATRIX=-1, 0, 0; 0, 1, 0; 0, 0, 1

Copy the entry that most closely resembles your make and model of computer, and paste it into a new file in the same folder (/lib/udev/hwdb.d/) called 61-sensor-local.hwdb.

Replace the model and manufacturer with your model and manufacturer, and change the values in ACCEL_MOUNT_MATRIX. Each axis, x-y-z, separated by a semicolon, can only have one non-zero number and it must be 1 or -1. Experiment with different values until you find what works. It's a pain because you have to reboot each time. Use the following two links as guides.

https://unix.stackexchange.com/questions/410826/change-iio-sensors-data-via-custom-accel-mount-matrix

https://www.aixin.fr/jipeblog/?p=119

Note, I said copy and paste the entry from 60-sensors.hwdb and replace the names instead of writing it from scratch because if you follow verbatim the instructions in the two links, you'll notice the asterisks are in different spots. It didn't work for me unless I mimicked exactly what was already in the config file.

Make sure you update your system using the commands in the aixin.fr
   link.


What are the original settings for Ayatana blacklist in Loki? 2 wifi icons

This file is in the elementary-default-settings package:

$ dpkg -S /etc/wingpanel.d/ayatana.blacklist
elementary-default-settings: /etc/wingpanel.d/ayatana.blacklist

You can download it and extract its contents

$ sudo apt-get --download-only --reinstall elementary-default-settings
$ dpkg --vextract /var/cache/apt/archives/elementary-default-settings*.deb /tmp

And now you check the contents of the file, overwrite the old one, etc. at /tmp/etc/wingpanel.d/ayatana.blacklist

Does EOS Loki work on the Surface 3 (non-pro)?

I don't think so, Microsoft is not so open about their bootloader and drivers, so its already pretty hard to install anything but Windows, but there is an even bigger issue with your config.

You're using a non-pro surface 3, this means you're running an ARM processor, not an x64 processor. Elementary is, sadly, not available for this kind of processors.

You could try any Linux distro that is ARM compatible.


Please define "supports" :) I'm writing this on my new Dell Precision 5510 featuring an Intel i7-6820hq (Skylake chipset), running elementaryOS 0.3.2 (Freya). My only kernel related issue has been the lack of out-of-the-box support for the Intel Wireless chipset responsible for wifi and bluetooth, but that was solved by installing a back-ported driver after installation.

So, getting the system running is absolutely no issue if you have a Skylake processor/chipset. Download the .iso and put in on a USB/CD and give it a spin (no need to install it to test it), and if it works, it works - and you can choose to install if so desired. Just a side note: if you already have an OS installed (like Windows 8/10), make sure to disable support for "legacy mode" (MBR) in the firmware a.k.a. BIOS. The risk is otherwise that the installer will install grub2 into the MBR instead of the EFI partition. I'm talking out of personal experience here :) (See http://elementaryos-on-dell-5510.compio.it for details)

Hope this answered your question!


The repository 'https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/hera pgadmin4 Release' does not have a Release file

Sometimes, desktop environment failed to start

This technique is work for me:

Open "Files" application as root
Browse folder: /etc/xdg/autostart/
Rename file: at-spi-dbus-bus.desktop to at-spi-dbus-bus.disabled
Restart

I can confirm that renaming /etc/xdg/autostart/at-spi-dbus-bus.desktop to /etc/xdg/autostart/at-spi-dbus-bus.disabled fixed the issue for me as well.


Why is Freya telling me I have no disk space left?

The best possible thing I can think of is 'your options did not save' at the time of partitioning and the installer somehow pointed to system defaults. Did you really save your partition settings before proceeding (and did not do back/forward clicks)?


How to setup your NTFS drives/partitions to mount on elementary OS startup?

Easy to set up using fstab. Run sudo blkid

and you should get something like this:

/dev/sda1: UUID="b9377d9b-639f-47da-ae99-efe277eb56b3" TYPE="ext4"
/dev/sdb1: LABEL="Backup 1" UUID="6177d371-80e4-49bd-bb77-de269e175c97" TYPE="ext4"

Save the UUID of the partition you want to mount. If you are unsure of the partition you want to mount use sudo fdisk -l to get more details of the partition.

Now edit your /etc/fstab:

sudo -i scratch-text-editor /etc/fstab

Add the following lines to your file:

#Windows Partition
UUID=<xxxxx> <mount point> ntfs rw,auto,users,exec,nls=utf8,umask=003,gid=46,uid=1000    0   0

You must replace the <xxxx> with your UUID and <mount point> with your desired mount point.

For the mount point you can choose something like /media/<user>/windows (which is the standard mount point for other partitions) or create a folder (without spaces) in your home directory and use /home/<user>/<folder> as the mount point.

Your file should look like this in the end:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=b9377d9b-639f-47da-ae99-efe277eb56b3 /               ext4    errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
#UUID=89bfd6b9-b2be-41c1-8c9f-5e7e5cb738d3 none            swap    sw              0       0
/dev/mapper/cryptswap1 none swap sw 0 0
#Windows Partition
UUID=b9377d9b-639f-47da-ae99-efe277eb56b3 /media/tim/windows ntfs rw,auto,users,exec,nls=utf8,umask=003,gid=46,uid=1000    0   0

After editing the file you should run:

sudo mount -a

If it returns any error, Do not Reboot (your PC may fail to restart), as you probably have some error in the mount point.

If everything goes well you should see your partition mounted.

elementary os natural scrolling disabled when disable while typing is on?

In the System Settings app there is a section called "Mouse and Touchpad" which contains check boxes for both "Disable while typing" and "Natural Scrolling". Checking both of these options seems to be at least a partial solution as it disables scrolling while typing (the mouse pointer continues to work) and preserves natural scrolling.


Is it possible to change the date format shown in Loki's menu bar?

After much research, this appears to be bugged. I tested multiple regions and thoroughly switched my entire system formatting to the UK (locale, keyboard, timezone). I clicked all the buttons, entered all the admin prompts, logged out and rebooted to test system changes, and still couldn't get the indicator to display in dmy format ("10 Sep"). (I had the same issue with the greeter too, for what it's worth.)

The desired setting for this is certainly Settings > Language & Region.

"Language" appears to successfully set the system language (and thus have the date in dmy in other languages that use that style)
If "Region" has an effect, it is not readily apparent, and
"Formats" visibly changes a date format shown grayed out on the screen. It would follow that changing the format from United States (mdy) to United Kingdom (dmy) that the menu indicator/greeter would change to match the change in the grayed out formatting (see image))

But alas, it does not work as intended. I filed these bugs:

Indicator's displayed date/time does not respect formatting set in Switchboard Locale Plug (Language & Region) (Related: Use same time format for greeter and indicator)
No feedback after clicking "Set System Language"

Please subscribe to the bug reports so that the devs can ask for help testing solutions. If you want to give the open source devs some extra incentive, try putting a developer bounty on the task. I'll report back when the bug is cleared.

Can't print to HP Officejet 5740 using elementary OS Freya

According to the official HPLIP-Database your printer needs HPLIP version 3.14.10 or newer.
Unfortunately elementary OS supplies HPLIP 3.14.3 by default, which does not support your printer.

You will need to install a newer version of HPLIP (choose Ubuntu 14.04 as distribution).

Please create a backup of your system before installing a third-party Application, just in case something goes wrong.

Can't transfer bookmarks from Midori-Granite to Midori

If you've installed Midori from the Software Center (or otherwise from the upstream Ubuntu repositories), you're running Midori 0.4.3. You can verify this by accessing the "About" dialog at the bottom of the gear menu.

The Midori that we build with Granite enabled is version 0.5.10. There's been a lot of work done in Midori regarding bookmarks between these versions. If you want the latest Midori without Granite (The one that is compatible with your bookmarks), you'll need to get it from the Midori PPA.

You can add the Midori PPA and install Midori from it by entering the following in Terminal:

sudo add-apt-repository ppa:midori/ppa
sudo apt update
sudo apt install midori

How to add PlayOnLinux's app shortcut to Plank?

You might need to add a .desktop file to ~/.local/share/applications

I would check to see if there is one in /usr/share/applications. If there is, copy that to the first directory I listed. If one does not exists, you might have to create one manually. But if you can launch it from the wingpanel than you have a valid .desktop file. It just need to be in the right place in order to pin it.


latest downloaded ISO file cant install bootloader on to flashdrive

This is usually caused by trying to force UEFI during install. Use the appropriate install method for your system, you should really never have to force UEFI. Try installing Elementary OS with your computers Legacy Boot option instead and see if you get better results.

How can I change the language of the LibreOffice's interface to Spanish?

To change user interface language in libreoffice:

Make sure the language pack is installed.

For this,open "Language & region " in system settings.

Click on comple install under "install missing languages" ,if the required language is not available.

Note: No need to change any other settings in that tab.

2.Go to libreoffice tools-->> options.. -->> language settings -->> language.

3.Now change User interface, Locale setting , Default currency , and default document language to desired language.

This will change the language only for LibreOffice, leaving other applications in English.


True, it starts happening after installing some input update.

Make sure you restart and run update again . It will fix itself

How to install elementary in a UEFI ASUS system?

You can create UEFI bootable USB drive (I'm use rufus) with elementary OS and boot from it. When you boot from USB with elementary you can install OS as usual and after it you will have two boot options in UEFI (also you can see LAN boot options if you enable it in BIOS):

Windows Boot manager
ubuntu

And you can choose main boot option and boot from it. If windows boot loader will be disabled or not present at list you can repair it with bootable Windows USB drive.


Is there a built-in graphical way to set the DNS on elementaryOS Loki?

You can edit a network connection in Network Settings, then you are able to add additional DNS servers which will work alongside the automatic ones from DHCP (which are generally provided by networking hardware / ISP), or else you can specify to use only the DNS servers you want by selecting Manual or Automatic DHCP (Addresses Only)

This is in the IPv4 and IPv6 tabs of the settings.

Editing /etc/resolv.conf manually doesn't persist, it will be automatically overwritten (which is normal as different connections require different DNS like office intranet etc.), so I'd move away from that approach if possible.

Hope this helps.


Unable to fullscreen video on second monitor

The same happen to me since Juno, with Loki I could without issue. Now is not possible to upscale any video content

The only way to bypass it is to maximize it/go fullscreen on the main display and then send it to the desired one (WINKEY+SHIFT+RIGHT_ARROW)

I couldn't figure out where to watch in the logs to check what happen

--

I use chrome to watch netflix and youtube in kiosk mode

just save the app shortcut then edit it and add --kiosk and --window-position=X,0

where X stand for the x coordinate where the second display starts

https://peter.sh/experiments/chromium-command-line-switches/

check your displays with:

$ xrandr --query

that will make chrome go fullscreen and load on the second display
for youtube -> youtube.com/tv (works awesome)


I gather from your question that your problem is the absence of the wifi drivers. If the process of installing the OS succeeded without any problems, you would not have to install the wifi drivers manually. Just try updating the os first and if it still does not work, please reply.
Sometimes the wifi does not work when you suspend/hibernate the system and then resume. Use sudo service netwrok-manager restart in such case to get your connections back or restart your pc instead.

Is there a terminal for elementary with the "badge feature" like iTerm
  for Mac?

I'm not aware of any Linux terminals with that will display a "badge" in the upper right-hand corner, but Linux terminals can display some of the same information.

From the link you provided:

  We can display some dynamic status like the current user, host name or
  git branch.

The username and host name should be displayed in the terminal prompt by default. It should also display the directory that you are in. There are some good sites out there on how to configure the prompt:

https://www.howtogeek.com/307701/how-to-customize-and-colorize-your-bash-prompt/

https://www.cyberciti.biz/tips/howto-linux-unix-bash-shell-setup-prompt.html

But if want the information displayed in the upper right-hand corner of the terminal, I'm not aware of a way to do that.


Slow performance issues in elementary OS vs OpenSUSE?

When a game starts up, it usually loads all relevant game textures etc. into the RAM of the GPU.

Are you absolutely sure that you got that video drivers right?
I had the same issue with a Toshiba laptop. Where elementary OS was running perfectly fine, Arch was very slow. I later found out that my APU drivers were not working on the Arch's 4.3 Kernel but Ubuntu's way older kernel it worked perfectly fine.


Right mouse click into the web page and choose "Inspect element" - it should open the web dev browser inspector with a lot of options for screen sizes including larger than your monitor (with some zoom applied). All browsers should have this option.


Wireless not connecting Lenovo v510 - How to download drivers?

We blacklisted ideapad_laptop in /etc/modprobe.d/blacklist.conf and it worked. Kinda just kept throwing stones at the OS until something happened but the logic was that lenovo's drivers were layered between the OS and hardware interface (as far as I understand it), thus we removed them.

The laptop is functionally perfectly now - loving this OS!

SIDE NOTE : I was told by a friend who had a similar issue that he had to reinstall Elementary OS and change some secure boot settings - but this was not attempted.

Thanks @Renato A. for the input! You were right about all drivers being present.


Can't boot into Elementary OS on Macbook without efi boot

I managed to fix the issue by reinstalling (though I don't think it was necessary) following these instructions, though I think it was mainly the last part that helped.


elementary OS does not support a global menu bar like Ubuntu or OS X. elementary apps do not use a menu bar, and apps that do use a menu bar display the bar in the window where the developers of the app intended it to display.

Any hacks or workarounds to extract menu bars from applications and display them in a panel are not supported and very likely will break your install (as has been seen several times on this Stack Exchange and Launchpad).


Problem with apt-get update in crontab @reboot

Try to "wait" a bit before running apt update. You can empirically find optimal time to sleep, or you can use this code from this post:

#!/bin/bash

function check_online
{
    netcat -z -w 5 8.8.8.8 53 && echo 1 || echo 0
}

# Initial check to see if we're online
IS_ONLINE=check_online
# How many times we should check if we're online - prevents infinite looping
MAX_CHECKS=5
# Initial starting value for checks
CHECKS=0

# Loop while we're not online.
while [ $IS_ONLINE -eq 0 ];do
    # We're offline. Sleep for a bit, then check again

    sleep 10;
    IS_ONLINE=check_online

    CHECKS=$[ $CHECKS + 1 ]
    if [ $CHECKS -gt $MAX_CHECKS ]; then
        break
    fi
done

if [ $IS_ONLINE -eq 0 ]; then
    # We never were able to get online. Kill script.
    exit 1
fi

# Now we enter our normal code here. The above was just for online checking


In the end I found that my system was using the elementary-os/daily repository.
Removing this, replacing it with ppa:elementary-os/stable, and reinstalling AppCenter fixed my problem.

elementary OS won't boot: displays "reboot and select proper boot device"

I've managed to figure it out. It seems that the main issue was that GRUB hadn't completely installed.

First, I used the elementary OS live-boot USB that I'd made with Rufus to boot into a live environment. I needed to install boot-repair, which needed a repository added. I ran:

sudo apt-get install software-properties-common

Which allowed me to run:

sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

I followed all instructions, made sure to ensure that GRUB was purged, and after reboot, the laptop booted up perfectly!

However, after the first reboot, the problem returned with an additional error message:

Failed to open \EFI\BOOT\grubx64.efi - Not Found
Failed to load image \EFI\BOOT\grubx64.efi: Not Found
start_image() returned Not Found

So I booted back into the USB live environment, opened a terminal, and ran

sudo bash
cd /boot/efi/EFI
sudo cp -p ubuntu/grubx64.efi Boot
sudo touch ubuntu/grubx64.efi.gbr

Now the laptop has no issues when booting. :D


This fixed it

sudo apt-get upgrade

silly me, should have done this first.


I was able to remove it by using dconf

sudo apt-get install dconf-editor #to install dconf-editor

Open dconf-editor --> org --> pantheon --> gala --> notifications.

Here you will see: apps the corresponding value should have entries like: 'appname:show,on'. But you will see an entry without appname like just ':show,on'.

(The actual syntax is :['{APP-NAME}:{PRIORITY (show/hide)},{SOUNDS on/off}', ...])

Remove it, it will remove the unknow notification icon.

After removing ':show,on':

You can make the notifications to default by clicking Set to Default in dconf (See screenshot above).

Using terminal:

Open terminal and run:

gsettings get org.pantheon.desktop.gala.notifications apps

It  gives the similar output:

['NetworkManager:show,on', 'Power:show,on', 'terminal:show,on', 'guake!:show,on', 'org.pantheon.noise:show,on', 'vlc:show,on', 'vlc media player:show,on', 'xneur:show,on', ':show,on', 'thunderbird:show,on', 'geary:show,on']

You will see ':show,on' in the output.

Now run:

gsettings set org.pantheon.desktop.gala.notifications apps "[]"

Inside the [], copy paste the above output except ':show,on'

For example:

gsettings set org.pantheon.desktop.gala.notifications apps "['NetworkManager:show,on', 'Power:show,on', 'terminal:show,on', 'guake\!:show,on', 'org.pantheon.noise:show,on', 'vlc:show,on', 'vlc media player:show,on', 'xneur:show,on', 'thunderbird:show,on', 'geary:show,on']"

Note: I have used \ before ! as escape sequence in the example.


What command is executed when I click "open as Administrator" in Files from the Dock?

It is pantheon-files-pkexec

You can find it in /usr/share/applications/pantheon-files.desktop. It looks like this:

[Root Shortcut Group]
Name=New Window As _Administrator
Exec=pantheon-files-pkexec
TargetEnvironment=Unity


The recommended spec :

4-bit processor
4 GB of RAM
15 GB of free hard drive space (SSD is better)

Clipboard manager with Pantheon integration

You can use "Clippy" docklet in the dock (Plank).

Open Plank preferences by pressing Ctrl and right/secondary clicking on Plank (or just run plank --preferences in the Terminal) and go to Docklets tab.

Drag and drop Clippy icon to the dock. Right-click on it will open simply clipboard manager.


I also faced same issue after installation.

Run

sudo apt update
sudo apt upgrade

Then open software-center.
Its worked for me.


Speakers make a pop sound on boot [Huawei MateBook D 14 Ryzen EU-Version]

This sounds like a hardware issue and not related to the Music app


I have not seen a bug like this (then again, I rarely look at the bug reports :P ).  Could this be a graphical glitch?  The system may be doing a large update, and it requires a great deal of system resources.  This could be what's causing the freeze: the system can't properly draw the animations due to the use of the resources.


Q: How to enable dock microphone by default when headphones with mic are plugged-in?

Can't check if eOS has pulseaudio installed by default right now, if it's not there then apt install first. Then follow this answer to automatically switch to a newly connected device.


Old Desktop will not boot Freya 0.3.2 i386 CD

If your system does not support booting from a USB try using PLoP boot manager. First you will need to copy elementary OS to a USB using Rufus.

How to install PLop boot manager

Install PLoP on a CD

PLoP comes as a ZIP file, which includes different files. To install PLoP on a CD, you will need either plpbt.iso or plpbtnoemul.iso from that ZIP file. Both disc images should work on most computers, though if in doubt plpbtnoemul.iso should work “everywhere,” according to read me included in the ZIP

Burn plpbtnoemul.iso or plpbt.iso to a CD.

Booting elementary OS from PLoP

Plug in your USB and insert your CD .Boot you computer from the CD and PLoP boot manager will load. It will look something like the following

Select your elementary OS USB and press ENTER


Google Maps freezes with Chrome on elementary OS

I experienced severe lag in Google Maps until I disabled Hardware Acceleration (Settings > Advance Settings > Deselect setting under System.)


It looks like your problem is the same as this. hope it helps.


Is it possible to use elementary OS from a live USB while persisting its data?

elementary OS does not officially support being used as a persistent live USB. However, the following method can be tried at your own risk:

It is possible to use third-party software to have your settings stored in the live USB. Any changes you make to the system—for example, saving a file to your desktop, changing the settings in an application, or installing a program—will be stored in the overlay file. Whenever you boot the usb drive on any computer, your files, settings, and installed programs will be there.

Ubuntu can be used with live use with persistent storage. And elementary is based on Ubuntu so it will work too.

Please follow these steps,

At first download the iso of the operating system and another software called Linux Live USB Creator.
Install Linux Live USB Creator. Insert the USB drive you want to use into your computer’s USB port and launch the “LiLi USB Creator” application you just installed.
Select the USB drive you want to use in the “Step 1: Choose Your Key” box.
Provide your downloaded ISO file. Click the “ISO / IMG / ZIP” button under “Step 2: Choose a Source”, browse to the .ISO file on your computer, and double-click it.
Use the options in the “Step 3: Persistence” section to select how much space your want to use for persistent storage on the USB drive. Drag the slider all the way to the right to select the maximum amount of storage.
You’ve now configured all the settings you need to configure. To create your live USB drive with persistent storage, click the lightning icon under “Step 5: Create”

Above instructions are grabbed from here which shows How to Make a Persistent Ubuntu USB Drive on Windows. However, the process is quite same.


Newb problems, yet another appcenter thread

Not all apps for Linux that exist out there are in Elementary's AppCenter. Only a subset of those hand-picked by the Elementary team.

That said most of the apps you see that are packaged for Ubuntu 14.04+ will work on Elementary. So you want to snatch the .deb file and then on the terminal do (example for skype alpha):

sudo dpkg --install path/to/skypeforlinux-64-alpha.deb
sudo apt install -f

In the future you might want to use ppa's instead, just so you always have the latest stable release installed. But that's a topic for another lesson, further down the road. ;)


Simple as that. Switch to terminal and learn how to use it. It is a must have in Linux.
sudo apt install nameofthewm

Change name of the app to the name of the Windows Manager you want to install.
If you want to remove WM. Switch to Pantheon and type:
sudo apt remove --purge nameofthewm


In my experience this kind of hang is due to a lack of GPU/video support. I'd say you need to boot into an un-accelerated 'safe' video mode and keep using it until you've run a full update (new kernel, new video drivers.)

Press 'e' on the try elementary os option and add 'nomodeset' (without brackets) to the portion that says 'splash quiet".

Install as usual and run a full update. Then remove the 'nomodeset' text from '/etc/default/grub' and run 'update-grub'.


Weird shadow/glow/smear on the right side of all windows

Seems like the issue was hardware after all. After tweaking with the monitor settings and with color presets I managed to mostly resolve the issue.


Add a new PPPoE connection in Terminal:
nmcli con edit type pppoe con-name "pppoe"
set pppoe.username ******
set pppoe.password ******
save
quit
Then nm-connection-editor, edit ethernet/wired, General tab, uncheck "Automatically connect to this network" for the ethernet/wired connection and leave it only for the PPPoE connection.


You can't update from Loki to Juno. You'll need to do a fresh install with a Juno iso.

Don't forget to backup your /home directory as well as your packages and ppas.


Have you tried installation as on https://www.foxitsoftware.com/downloads/thanks.php?product=Foxit-Reader&platform=Linux-64-bit&version=1.1.0.0225&package_type=run&language=English advised?

filename.run executable will be start with ./filename.run
Also you can start it from filemanager with right click extract.
I have tested Foxit Reader without problems.


FIRST METHOD

Create a file, I'll name it no-flip.sh, in /opt

sudo nano /opt/no-flip.sh

Copy this text and paste it into the file and save it

#!/usr/bin/env sh
xrandr -o normal

Execute

sudo chmod a+rx /opt/no-flip.sh

Edit

sudo nano /etc/lightdm/lightdm.conf

Add the lines

[SeatDefaults]
display-setup-script=/opt/no-flip.sh

Reboot

I used nano as my text editor, you can use anyone you like

SECOND METHOD

Create the file /etc/X11/Xsession.d/45custom_xrandr-settings write in it:

# To configure xrandr automatically during the first login,
# save this script to your computer as /etc/X11/Xsession.d/45custom_xrandr-settings:

# Based on https://askubuntu.com/a/678301/890782

# No Flip
xrandr -o normal

NOTE

This should work, at least in theory. Right now doesn't work because you ran the command in the user environment hence when you log out from that user that process is terminated. The theory is that you need to run the command system-wide, and this is one possible method.


Games installed through GOG do not work, but Steam games do

This is a late answer, but I'll try to help in case you're still having this problem or if someone else stumbles upon this page. :) Note that this might not be a recommended or most optimal way of solving these kinds of issues, but it's how I do it.

  My assumption is that it has to do with Elementary being 64-bit

This can indeed be the case. You can enable the installation of 32-bit versions of packages by running this command in the terminal:

sudo dpkg --add-architecture i386

This needs to be enabled for the following to work.

So, next I'll show you GOG's version of Crimsonland as an example. It did not launch right away, so I ran it through the terminal. You can launch a terminal in the game's folder by navigating to it in Files (Home -> GOG Games -> Gamename), right-clicking the file area and choosing "Open with an application -> Terminal". Then run the command ./start.sh as in the following image. Most, if not all, Linux GOG games are run via the file start.sh

Notice that the error message shows the name of a library: libopenal.so.1

Now you need to figure out what package this might relate to. I searched for libopenal by using the Synaptic Package Manager application available on the elementary AppCentre. I found a package called libopenal1 of which the 64-bit version was already installed. I decided to try installing the 32-bit version of it as well.

I closed the Synaptic Package Manager and issued the following command on the terminal:

sudo apt install libopenal1:i386

Notice the important part: I put :i386 at the end of the package name. This means that I am asking apt to install the 32-bit version of the package.

I proceeded with the installation and afterwards tried starting the game again. It worked!


why won't freya 64bit or loki 64 bit work on my computer?

Just because your Intel® Core™2 Quad Processor Q6700  supports 64-bit doesn't necessarily mean that it's 64-bit mode supports everything elementary OS requires. Seeing as this is a 2007 CPU, I would guess that some 64-bit modes are not available, likely related to the graphics.


Are there different ways to create new workspaces in Loki?

With dynamic workspaces enabled (which is default in elementary OS), you cannot create workspaces explicitely but

a new empty workspace is created by switching to the right of the rightmost existing workspace or
a new workspace is created by moving a window right to the rightmost existing workspace.

If you disable dynamic workspaces (via the command line here):

gsettings set org.pantheon.desktop.gala.behavior dynamic-workspaces false

you can set the number of workspaces wanted to NUMBER:

gsettings set org.gnome.desktop.wm.preferences num-workspaces NUMBER

In this case, you can create new workspace by changing the number on-the-fly. For instance, you could create a script that does that and assign a custom shortcut to this script in System Settings/Keyboard (Shortcuts tab).

cf., How to disable the empty workspace that appears when switching between them?


Same problem with an Nvidia graphic card (GeForce 210). After an update, I couldn't login to the main account. After some research and trying different things, this solved it for me:

When you are in the login screen, enter the terminal by pressing ctrl+alt+f1 and then:

sudo apt-get remove bumblebee
sudo apt-get remove nvidia*
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo ubuntu-drivers list
sudo ubuntu-drivers autoinstall

Reboot

Hope this helps.


Elementary OS 5.0 Juno is not using ibus as input method

You can try the following:

Open im-config through terminal

sudo im-config

click OK button to go next

Click Yes to update system config.

Select Ibus as input method for the system

Click Ok and Ok for the next windows. Then restart your computer.

The sudo at step 1 is crucial. Without sudo the system just uses the default setting regardless of what you have chosen.

Also make ibus-daemon auto start with the system by:

System Settings > Applications > Startup

Then add a custom command:

ibus-daemon -drx


The elementary team typically only supports the latest release with feature updates, which I think is mainly a volunteer issue than anything else. The team tends to not set firm release dates and follows a "done when it's done" mentality. So now that Loki is released, there isn't a set date for Freya's end-of-life, but Freya-specific issues will likely not garner much attention. You can track the progress on the next release, Juno, here. That will likely be as close as it gets to Loki's end-of-life.

The OS is built atop Ubuntu "Long Term Support" releases, which also stop receiving feature support after about nine months but do receive major security fixes for five years (April 2021). The team pushes those security updates to former releases and will post in a public place if for some reason an older release cannot update (users would be expected to upgrade for security reasons at that time).


Basically you should separate your /homeand / partitions on your existing system.

Boot the elementary OS live DVD/USB system you want to install
With gparted you should shrink your existing root partition and create a new partition (10-12 GB should suffice)
You can install elementary OS to the new partition
You can mount the old partiton as /home while installing the new system
After your newly installed system is working, you can gain some space by removing the old system from your /home partition
You might as well restructure it so that your documents appear in your new /home folder (you will find them in /home/home/username)


I had this issue with my XPS 13 9730. It's due to UEFI boot being set in BIOS. You need to enable Legacy Boot. I'm trying to work out how to force Elementary OS to install as UEFI because Legacy is much slower.


Software updater doesn't work anymore correctly

You will need to open the terminal and type these commands:

sudo apt-get update

Wait after process update's done.

Then run this command

sudo apt-get upgrade

Have you tried that command on your terminal? Then of the end command update and upgrade list what's the result? Any error notes on your terminal?


Boot Issue After Formatting and Changing Mounting Points

To boot into single user mode you edit the boot instructions for the GRUB menu entry you wish to boot and add the kernel parameter/option single. Brief instructions for how to do this are below.
Turn on laptop and wait when GRUB menu will appear. Select (highlight) the GRUB boot menu entry you wish to use. Use the first one entry in this case.
Press e to edit the GRUB boot commands for the selected boot menu entry.
Look near the bottom of the list of commands for lines similar to
linux /boot/vmlinuz-5.7.0 root=UUID=bc6f8146-1523-46a6-8b
6a-64b819ccf2b7 ro quiet splash initrd /boot/initrd.img-5.7.0

Change the line by removing quiet splash and by adding the kernel boot parameter single to the end of the line (it should look exactly like this: ro single).
For this example you would change:
6a-64b819ccf2b7 ro quiet splash

to
6a-64b819ccf2b7 ro single

Press either Ctrl+X or F10 to boot using these kernel options.
Note: These changes are not persistent. Any change to the kernel boot options made this way will only affect the next boot and only if you start that boot by pressing either Ctrl+X or F10 while still in GRUB edit mode.
Then run the system and see errors on the screen and provide a photo of the screen with errors or information the system shows.
Then you should hit Enter to go into maintenance mode and type in terminal.
journalctl -xb

and hit Enter.
It will show you all information from the boot start process to the end, I mean to the moment you hit Enter to go into maintenance mode. To quit viewing hit q.
Provide screenshots. Use arrows or PgUp PgDown to scroll text in the screen.
Then very important step is to show the fstab.
sudo cat /etc/fstab

Example: how fstab should look like:
UUID=89ef95ac-3c86-4b94-a37c-da8c72a148fa /               ext4    errors=remount-ro 0       1
# /boot was on /dev/sda6 during installation
UUID=8b4947b6-c0c9-4b1f-87ed-ef698609be22 /boot           ext4    defaults        0       2
# /boot/efi was on /dev/sda2 during installation
UUID=C8CA-DC0F  /boot/efi       vfat    umask=0077      0       1
# /home was on /dev/sda7 during installation
UUID=21f30bb7-2c7a-405f-bb16-b37901eeda09 /home           ext4    defaults        0       2
# swap was on /dev/sda5 during installation
UUID=c98dd990-02e1-4872-9de0-d00601e5aa7a none            swap    sw              0       0

Edit the /etc/default/grub
sudo nano /etc/default/grub

and change:
GRUB_CMDLINE_LINUX=""
to this:
GRUB_CMDLINE_LINUX="mount.timeout=300s"
ctrl+o saves, ctrl+x exits
Type
sudo grub2-mkconfig -o /boot/grub2/grub.cfg and restart.

To restart type:
 systemctl reboot

And hit Enter.
Then you can repeat all steps but instead of hitting Enter, hit Ctrl+d to run the system.
See will it load with default options.
The same effect you will achieve when you will hit Enter instead Ctrl+d and then type:
systemctl default

and hit Enter.


With the first system, you can't install it at all. eOS is a 64 bit OS. Those are limited to the 32 bit architecture. You'll need a 32 bit OS.
With the second system, you can install it - but your performance will be pretty poor.
These are the minimum requirements for the current version of eOS:

Recent Intel i3 or comparable dual-core 64-bit processor
4 GB of system memory (RAM)
Solid state drive (SSD) with 15 GB of free space
Internet access
1024×768 display

You meet most of the requirements, but you do not meet the minimum RAM requirements. The device you linked only has 2 GB of RAM, or half of the minimum recommended amount. The next version will have at least the same minimum requirements.
It'll probably run, but it won't be very fast. You will be very disappointed with the performance.
So, what can you do?
For the first systems, you can search DistroWatch for 32 bit systems.
For the second system, and for the first, you can use this handy list of lightweight Linux distros.
Don't fret, however. If you follow those two links, there are many choices for you to pick from. It isn't too hard to find a distro that works well and suits your needs, nor is it all that challenging to make them aesthetically pleasing.
They (the Linux community, not eOS) haven't stopped developing for 32 bit, but it has slowed because there are fewer people to test on 32 bit hardware. eOS has made the decision to not support 32 bit computers at all.


Make a backup and then re-install elementary OS. That fixed it for me.

Don't use "software update".


How can I get Plank and Wingpanel on both monitors without Mirroring Screens

Plank (Buttom Dockbar):
It's really easy to mirror plank to more than one screen.

Make sure that dconf Editor is installed:sudo apt-get install dconf-tools.

Convert existing dock into dock1 and add dock2, dock3 .. :cd ~/.config/plank & mkdir dock2 dock3 ..

Copy settings files:cp dock1/settings dock2/ & cp dock1/settings dock3/ ..

Link icons form dock1 to dock2,..:ln -s dock1/launchers/ dock2/launchers & ln -s dock1/launchers/ dock3/launchers ..

Identify monitor IDs:xrandr | grep " connected"Output: eDP1 DP1-2 DP1-3 ..

Set monitor for dockX:sudo nano dockX/settingsMonitor= eDP1/DP1-2/DP1-3/..

Apply settings to pantheon:Apps -> dconf Editor and org -> pantheon -> cerbereReplace '..plank..' with 'plank -n dock1 & plank -n dock2 & plank -n dock3 ..'

Sources:Fun tip: Have plank run on multiple monitors!Dual docks in elementary OS

Wingpanel (Top Systembar):
Update: There is a ported version of autohide available here, WingPanel » Add optional hide mode.

Bug #1237228
It should be an option to have wingpanel placed on multiple monitors. >Perhaps the monitor number could be specified through a command line argument so that any combination of instances/monitors could be achieved.

How to install wingpanel-slim or super-wingpanel on elementary 0.3 Freya (amd64)?
Both wingpanel-slim and super-wingpanel were developed and maintained by a developer on Launchpad called ~heathbar. Unfortunately, it looks like he abandonded both projects and did not update them to work with Freya (last change to wingpanel-slim was 2013-11-19, last change to super-wingpanel was 2014-03-04).
Therefore, sadly, there is (currently) no way to use one of those on Freya. Maybe development will be resumed by someone else, but at this very moment, it's simply not possible.

(Freya) Make Wing-panel Clear
Install dconf editor (sudo apt-get install dconf-editor)
In dconf-editor: org>pantheon>desktop>wingpanel
Unselect auto-adjust-alpha and set background-alpha to 0.0. Done :)


What is the recommended way to update from elementary OS Loki 0.4 to Loki 0.4.1?

Step 1. Update

Open up AppCentre
Navigate to the Updates tab
Install all available updates
Reboot if required

Now your System Settings > About section should look like the following image. Note that it states "elementary OS 0.4.1 Loki", not 0.4.

Step 2. Upgrade Kernel [Optional]

While your system now runs the latest version of elementary OS, it may not be running the latest kernel underneath. If you experience no problems with your hardware, this upgrade may only create minor performance imporvements. However, if your brightness or wireless was unsupported, this may fix some of your problems.

This is dangerous. You should create a backup before proceeding.

sudo apt-get install --install-recommends \
    linux-generic-hwe-16.04 \
    xserver-xorg-hwe-16.04 \
    xserver-xorg-core-hwe-16.04 \
    xserver-xorg-input-all-hwe-16.04 \
    xserver-xorg-input-evdev-hwe-16.04 \
    xserver-xorg-input-libinput-hwe-16.04 \
    xserver-xorg-input-synaptics-hwe-16.04 \
    xserver-xorg-input-wacom-hwe-16.04

Once this is complete and you have rebooted, you should see Linux 4.8.* in the elementary section of the About settings panel, instead of 4.4.*


Pantheon Files: Search results in window instead of drop-down list?

This is currently not possible. You may report a "wishlist"-priority bug to launchpad for pantheon-files so that a designer may consider adding this option, even though it is probably unlikely unless you can make a good point about usability.

After internal discussions we put a strong limit on the total number of search results, mainly because you are expected to refine your search terms if you get a too large number of results, instead of going through a big list.

There are programs dedicated to searching like the gnome-search-tool or recoll for full text search, if you wish to have a different representation of search results it may be best to try one of those.

Can't Connect my University email to Geary

It's kind of hard to figure out since I can't replicate the issue, but I'm going to presume that the not SSL part in the description on the website means that you should change the encryption method to None for both IMAP and SMTP.

A bit off-topic: Not supporting the encryption for you school's email is a really bad idea by the school's administration.


How to enable Alt-F2 command execution with tab-completion?

As mentioned in the other comments in that bug report thread, there are a few other options using external software, to enable full Alt-F2 functionality.

There's gmrun and synapse, both of which are available in the apt repository sources to install (sudo apt install gmrun, or sudo apt install synapse).

xfrun4 is also mentioned as part of xfce4-utils package, but that one doesn't seem to be available in the default repo sources.

gmrun is a very small download (<100kB) that produces a simple text box with tab-completion and history, no bells and whistles beyond that.

synapse tries to be more comprehensive, perhaps similar to 'Launchy' for Windows or 'Spotlight' on MacOS. It has a pretty good-looking GUI, has those core features of tab-completion and history, along with the ability to search your Images, Audio, Documents, etc. optionally. That predictably brings in allegations of being "bloated" as mentioned in the thread, though that's obviously subjective and depends on your preferences.

To enable the shortcut key:

for gmrun: go to System settings -> Keyboard -> Shortcuts tab, choose Custom in the left panel, click on the + button at the bottom and enter the name of the program (gmrun). Then click on the text that says Disabled next to the command name, and press Alt-F2 to assign that shortcut to it.
for synapse: go to System settings -> Applications -> Startup, click on the + button at the bottom and enter the name of the program (synapse), choose the Synapse program entry shown there. Then, if you wish to have the shortcut to be Alt-F2 instead of the default Ctrl-Space (which didn't reliably work for me, for some reason), start synapse manually from the terminal or Launcher, click the small circle on the top right and choose Preferences, and there change the shortcut for Activate to Alt-F2. (If the Preferences window doesn't show the actual shortcuts, right click on the window's titlebar and choose Maximize.)


How can I report an issue or request a feature for elementary OS to the developers?

elementary has provided a thorough bug reporting guide that explains how to file good issue reports in the right place. In short:

Find the Issues page for the app in question on GitHub
Be specific in your summary. Avoid subjective or ambiguous adjectives. Be concise and avoid chatter, but make sure to explain the whole issue.
Be prepared to supply more information. If the issue can't be reproduced with the supplied information, a developer may ask for clarification. If you do not respond, your issue will be marked as incomplete and may be closed.

What if I'm not sure that it's a bug or not?

Sometimes it's not immediately clear if something is a bug or a feature. You can and should file it anyways. Part of reporting issues is confirming them. Even if something was done intentionally, you can start a discussion about changing that behavior.

What if it's a feature request?

elementary tracks feature request as bug reports. You should file your feature request following the same guidelines. A bug manager will mark it with the "wishlist" status.

I want to make sure it's not a duplicate before filing

You can search for the issue in GitHub. If your report happens to be a  duplicate, select it from the search results and add the thumbs up reaction . Please don't make "me too" comments as this can obscure useful information that would help resolve the issue.

I don't know which project to file against

That's okay! Try to do your best to choose the correct project. If you've filed against the wrong project, a bug manager may ask you for more information to help you file against the correct project. Just be prepared to respond.

This issue is very important to me and I want it fixed right away

Most of the developers working on elementary OS do so on a volunteer basis, so it may take some time for your issue to be confirmed, assigned, and addressed. However, if you want to draw more attention to your issue you can consider placing a Bounty on it.


GTK 3.22 migration of older gtk.css -> Black Margin on elementaryOS apps

It seems that .window-frame got changed in GTK CSS 3.22 from 3.18. For the sake of Google I coulnd't find into what got changed (someone mentioned frame but that doesn't work).

So I got a brutal patch that seems to kind of work and have few side effects:

* {
   box-shadow: none;
   margin: 0px;
}

hope this helps others while a proper solution is discovered.


Same issue. I am assuming you've followed the directions from the installation guide on the PIA website for 'Linux'.
This works, not the best solution because you have to do this every time you log in to your linux session, but it works.

Open terminal. Enter these commands.

sudo apt-get install openvpn

this installs openvpn (if you didn't have it)

cd /etc/openvpn

this changes your dir to where the program you just installed is located

sudo wget https://www.privateinternetaccess.com/openvpn/openvpn.zip

this downloads a bunch of files you'll need

sudo unzip openvpn.zip

this unzips the zip

ls -l

this shows you a list of the config server files you just unzipped. pick a file to use and then...

sudo openvpn 'filename-goes-here.ovpn'

(e.g. sudo openvpn 'US East.ovpn') make sure you use the apostrophes!

Then it'll ask for your user name and pwd. Put them in and you're running your VPN. When you log out, restart, etc you need to open the term and enter some of the commands again as follows..

  cd /etc/openvpn

  ls -l

  sudo openvpn 'filename-goes-here.ovpn'

There are better ways to do this, but this will get you going in the short term.


I installed Synaptic Package Manager from software center. You can install it through software center or using the following command on your terminal

sudo apt-get install synaptic

Than I tried to fix using synaptic.  But it doest not solve my problem and again it's not installing Vlc player. So I used the following command to Fix it.

sudo apt-get update --fix-missing

After that Vlc installed. But it doesnot open. So I moved to get another command to fix the broken installation again.

sudo apt-get --fix-broken install

The above command fixed it and than its working fine now.


Skype for Linux Alpha Wingpanel Indicator

There is a mod for this on Ask Ubuntu. It allows you to use any icons you want, but the package listed to download is a monochrome that goes well with elementary.


The first step, install wmctrl package:

sudo apt-get install wmctrl

Description from the wmctrl homepage:

  The wmctrl program is a UNIX/Linux command line tool to interact with
  an EWMH/NetWM compatible X Window Manager. The tool provides command
  line access to almost all the features defined in the EWMH
  specification. It can be used, for example, to obtain information
  about the window manager, to get a detailed list of desktops and
  managed windows, to switch and resize desktops, to make windows
  full-screen, always-above or sticky, and to activate, close, move,
  resize, maximize and minimize them. The command line access to these
  window management functions makes it easy to automate and execute them
  from any application that is able to run a command in response to an
  event.

Next step, download and install script, prepared by me:

cd /tmp && wget https://github.com/png2378/showdesktop/archive/master.zip
unzip master.zip && cd showdesktop-master
sudo mv showdesktop /usr/local/bin/ && sudo mv showdesktop.desktop /usr/share/applications/ && sudo mv showdesktop.svg /usr/share/icons/elementary/apps/48/

The finish step, add icon on Plank:

mv showdesktop.dockitem ~/.config/plank/dock1/launchers/

Result:


Anyone tried getting netatalk working on elementary os?

yes.

sudo apt install netatalk

I am currently using Pantheon with netatalk for file sharing and Time Machine


No desktop after logging in - fresh install

Try renaming at-spi-dbus-bus.desktop:

sudo mv /etc/xdg/autostart/at-spi-dbus-bus.desktop /etc/xdg/autostart/at-spi-dbus-bus.disabled

I think you're running into this bug:

Bug#1596377

I had a similar issue and this fixed it for me. You might have to boot into recovery mode to access the terminal.


Elementary OS Desktop multitask view through terminal

You can trigger this through dbus: dbus-send --session --dest=org.pantheon.gala --print-reply /org/pantheon/gala org.pantheon.gala.PerformAction int32:1. This is how the .desktop file opens the multitasking view (https://github.com/elementary/gala/blob/master/data/gala-multitaskingview.desktop.in).


Can't install Freya, ACPI PCC probe failed

I got the same error on my first attempt at using elementary OS. Turned out that my install media (USB install disk) had mot been written properly. I just reinstalled the .iso file onto the same usb stick and everything worked smooth as butter.


I found a fix. I manually added the printer using the + button on the printer menu in Settings and finding it in the list, then enabled it and set it as default. Then I opened the terminal and used lpq to configure it.

The commands I used are:

lpq enable

lpq up

Then I was able to print from LibreOffice without issues.


I am pretty sure, they use Google.

However, elementary OS introduced AppCenter, you can find it in your Applications menu. AppCenter is capable of automatic discovery of updates for your system and a powerful search feature for Applications you may need.

I.e. elementary does not come with preinstalled Office-like system, so you may want to try LibreOffice. Just open AppCenter,type LibreOffice in the search box and see what happens: .

Next, select LibreOffice (it shall install package with all needed dependencies for ready-to-use business toolkit). As you may see you may select different parts.

Applications in elementary OS are collected using packages. These packages may have their own dependencies. For example, if there would be a package named "Minecraft", it would depend on "Java".

Thanks to AppCenter, and APT mechanism you need not to worry if your dependencies will be broken. APT takes care of dependencies automatically.

Google for Debian Manual, where it's perfectly described. elementary is based on Ubuntu, which is based on Debian.

Thanks, Michal @mjwhodur

You have also manpages, where you can learn about specific commands i.e.:

man apt

man apt-get

man bash


First when it freezes press ctrl-alt-Fx , Fx is any of the F1 F2 F3... etc. keys.

Then there will be a terminal asking for login, Enter your user name and Password.

After that run the top command. You will get a output of a table with the most CPU exhaustive applications listed at the top of the table. From here you can know which process is the bug. If it's an application then report it to one of there websites as a bug.

You can after that restart yur computer from the terminal itself by using the command sudo shutdown +0 -r increment +0 to increase the time in minutes after which the system shuts down and remove -r to not restart the computer if you like.


Unable to set a Static IP Address in elementary os

Elementary was originally based on Ubuntu, which was originally based on Debian.

You can set a static IP via the Network settings GUI.

Click Applications menu.
Click System Settings from the menu.
Click Network from the settings app.
Select your network connection in left-hand sidebar.
Click Advanced Settings in the lower-right corner.
Click the IPv4 settings tab.
Select Manual as the configuration method.
Set your IP.
Repeat on the IPv6 tab if needed.
Click Save.


Elementary on 2 in 1 laptops - Touch screen

Loki has compatibility with touchscreen, at least in my case (Asus X550C).
Just like you, I have Windows 10 installed along with Elementary. When I was in Freya, touchscreen was not supported and didn't work properly, but recently since I upgraded to Loki it works like a charm, just like in Windows. So yes, install Loki and you will be able to use the computer as a tablet.


In elementary OS you can install wine either via the AppCenter (search for wine and click Install) or via the command line:

sudo apt install wine


I recently tried to follow that guide you linked and failed as well.
The problem, as it was for me, is probably a misplaced or misconfigured config file.

You should check that you have the file named config (without an extension) in the right folder (/home/USER/.config/ladspa_dsp/), and create it if it's not there.
Then try running listplugins: at the beginning you should see something like this:

  /usr/lib/ladspa/ladspa_dsp.so:
         ladspa_dsp (2378/ladspa_dsp)

Don't worry about the LADSPA_PATH warning, it's not important.

Next you have to check the contents of the config file. In my case, the input_channels=2 was missing, and after fixing that everything worked.
Try to use the simplest config possible at first, e.g. the example reported in the guide.

If this doesn't work, it would be useful to have a more verbose output of the error. It can be obtained by modifying the default.pa as in the guide file and running pulseaudio -v.


Adding support for the “hevc” format to VLC without using ppa

You can upgrade to VLC 2.2.x or higher to get HEVC/H.265 support.To upgrade to latest version please refer

how-do-i-install-the-latest-version-of-vlc-media-player

(here you need to install gstreamer1.0-libde265 separately)

To add support to hevc with out PPA please refer here,I am just copy & pasting commands here.

 sudo apt-get update
 sudo apt-get install git -y
 cd /tmp
 git clone https://github.com/mmstick/ubuntu-10bit-encoding-tools
 cd ubuntu*
 ./install.sh

It's pretty easy, first add the fish shell repository:
sudo apt-add-repository ppa:fish-shell/release-3

Then just updated your repos:
sudo apt-get update

Now we can install it:
sudo apt-get install fish

One more command and we are done:
chsh -s /usr/bin/fish

This last command will switch your default shell to fish. To see the changes close your terminal and open it again. If you didn't notice any changes try logging out and logging in.
Bonus tip: Fisher
Fisher is a concurrent plugin manager for the fish shell, it supports Oh My Fish plugins, it's fast, and powerful.
To install it run:
curl -sL git.io/fisher | source && fisher install jorgebucaran/fisher

Bonus tip: Oh My Fish
If you know zsh you probably know Oh My Zsh, well fish has a similar port, named Oh My Fish
To install it run:
curl -L https://github.com/oh-my-fish/oh-my-fish/raw/master/bin/install | fish

A side note, when you do this your fish shell configs are overwritten, quoting the README file:

NOTE: The installation script renames your existing config.fish to config.orig, and replaces it with the default oh-my-fish config. If you have existing customizations to your fish config, you will need to manually include those customizations after the install.
If you want to install it manually, click here.

Note:
If by any reason you need to get back to your old bash friend, just type bash on your terminal, this will switch temporarily to bash, if you type exit or close the tab/terminal it will switch back to fish.


What are the essential things to know about using the Meson build system?

Meson is definitely something we're working towards in the future, but we haven't included it in the dev guide because we're still testing it and there are a couple of gaps. When we're sure that using Meson will be simpler and more streamlined than using CMake, we'll replace it in the guide. That said, Meson has great documentation on their website and I suggest starting with their tutorial.

Harvey's Meson has a few things that you might not need in your app like libm, gresources, gsettings schemas, and tests. I pushed a couple revisions just now with some simplications I learned recently, if you still would like to use it as a reference. Really the most important thing you need to build your app is this block:

project('com.github.yourusername.yourapp', 'vala', 'c')

executable(
    meson.project_name(),
    'src/Application.vala',
    'src/MainWindow.vala',
    dependencies: [
        dependency('glib-2.0'),
        dependency('gobject-2.0'),
        dependency('gtk+-3.0'),
    ],
    install: true
)

In the first line you declare your project name and the programming languages used (We need c because Vala compiles down into C). Then in this next block we tell Meson that we want to:

Build an executable binary file when we execute ninja in Terminal and we're going to call it the same thing as our project name (com.github.yourusername.yourapp)
Include src/Application.vala and src/MainWindow.vala as the files we are compiling
Use the dependencies listed in this array to compile our vala files. These are the minimum dependencies required for a Gtk+ app
Install this executable to the appropriate location when we execute ninja install

With the above in a file called meson.build you can open up Terminal and run meson build --prefix=/usr, then cd build and ninja and that's all you really need to get an executable. Then to install ninja install.


How do I set Tor Browser as the default browser for elementaryOS?

Worked it out by doing the following:

~/.local/share/applications
./start-tor-browser.desktop --register-app

Now Tor is sitting in my Applications launch area. I had no idea hwo to do this until I saw your instructions above. Many thanks.

How do I change the folder where screenshots are saved?

I tried to fix this myself but I don't believe there is a simple way. However, there is a workaround that I'm using.

set your folder dir in dconf-editor (as you already did)
map custom command io.elementary.screenshot-tool to Print button using the keyboard settings

That's it. Now each time you hit Print button you'll get the screenshot-tool opened, but most importantly, the app will have you folder dir from gsettings set as default.


Problems running three monitors with Loki

You might want to use xrandr to define the monitor resolution.
That's what I did for my second monitor (using an Intel card and not Nvidia).


New session when the lockscreen shows up (or when my laptop goes in standby)

Did a bit of research because nobody was really replying anymore, and came with a solution, but it's a hard workaround, at least it works, but if you have a better solution, I will accept that answer.

Not all steps have to be nessecary but I don't have the time to further check it out.

Here is what I did:

I removed pantheon-greeter and installed unity-greeter.
After reboot I reversed the process again
Then in settings I declared this new hotkey:

Now I can lock and unlock!


My Wingpanel bar is suddenly black with and without fullscreen app

This has basically been asked. This should fix your problem:

How to adjust wingpanel transparency in loki?

If not, I would suggest changing to a different theme then back to elementary. Since the wingpanel theme is dictated by the GTK theme this might just reset things back to the way they should be.


How to version my customized elementary OS

Actually uname shows information about the Linux kernel. So its output should only be changed if you have built a customized kernel.

However, if you have a custom distribution you should put this in the /etc/issue and /etc/issue.net files, like

user@machine:~$ cat /etc/issue
elementary OS Loki \n customized \l


Can't mount Windows partition r/w anymore

That's the thing. Even though you think that you have completely shut down your Windows system, you really didn't. Windows keeps the drive mounted so it can speed up its boot process (this has nothing to do with fastboot, it's a normal Windows behavior since Windows 8).

Try turning off your Windows system by typing this into your cmd:

 shutdown -s -t 0

This command will shut down your Windows system completely and you will be able to use the partition from the elementary installation.

Note that the command will shut down your system immediately. To set a time interval, you can change the 0 at the end to 30, which will shut down your system in 30 seconds. If you don't include the -t 0 at the end of the command, I think that the default behavior is to set the time to 60 seconds.

As an alternative, you can mount the partition as read-only by typing this in your terminal:

sudo mkdir /media/Windows
sudo mount -o ro /dev/sdaX /media/Windows

You only have to execute the first command once.


You can setup this at System Settings > Displays.
There should be an option that says "Use this Display".

You can also close your laptop lid while there is an external monitor connected. That will turn off the laptop integrated display and set the external monitor as the main display.


How to show the support status of packages in freya?

While what you saw was likely a bug and I'm on Loki (the next release) and unable to check this in Freya, I think there are a few things worth clarifying. While elementary OS is based on Ubuntu Long Term Support editions, "support" has a really specific scope. Major Ubuntu releases are "supported" with fixes and upgrades for nine months and the five-year "long term support" is reserved to critical/security patches. The elementary OS is based atop Ubuntu but holds its own release schedule and rarely has time to support prior releases following the next's release, save for major issues. (And there are surely plenty of bugs to squash in Loki...) This is all to say that elementary OS "support" is closer to nine months/one year: the latest release. While you can remain on Freya and hopefully receive Ubuntu's upstream base security updates, the rest of the elementary stuff atop Ubuntu will be left behind early into that five-year support period. But there likely isn't enough planning within the project to give an official list of supported software when it changes so often.

For ubuntu-support-status, which is a part of ubuntu-update-core, as far as I can tell, this is not intended to work with elementary OS, isn't included in the default repos, and hasn't been discussed in the bug tracker.


After some time I found how to solve that problem. Someone else had a similar one. Here is the link:
https://askubuntu.com/questions/213712/how-can-i-change-mouse-keymapping


Use ll or ls -al shell commands, you will see this directories have more permissions than normal one. Compare the permissions with the ones of home directories.


CTRL + SHIFT + key when using CTRL+SHIFT to switch keyboard layout

Opt+Shift is the default shortcut for changing keyboard layouts in Loki, so you'll need to change that if you want to use the same modifier keys for other shortcuts.

You can do this at Settings > Keyboard pane > Layout subtab > "Switch layout"


Loki WingPanel Takes a Long Time to Load and Stops Responding

I regularly notice a heavy fan activity when software is updated from within the appcenter after the system has booted, combined with a retarded system response to mouse klicks and keystrokes in other programs like browser etc.
From the shell, when I run the "top" command, I can see wingpanel consume a lot of CPU. It seems that wingpanel is caused to loop somehow.

After the updates are done, I note wingpanel's PID, terminate "top" with CTRL-C, and "kill " wingpanel. The system then gets back to normal (quiet fan and a hardly visible wingpanel in "top").


Connect and reconnect automatically to the VPN

You can have the VPN autoconnect by first setting up a vpn connection under the network settings. Then go to the ethernet or wifi tab and click on settings. Then under the general tab you can set it to autoconnect to the selected vpn for that connection.


Unresponsive desktop after login because of maya

I was experiencing the same unresponsive behaviour yesterday after an update. I couldn't track it down to Maya, but basicly the whole system froze a few seconds after login.

For me, the issue was resolved today by updating the system again:

Go to console after the system has started up (ctrl+alt+F1 or just ctrl+F1)
Run sudo apt-get update followed by sudo apt-get upgrade
Reboot


I'm afraid we broke that in the last Gala release when we tried to remove a lag / freeze when making screenshots (See: PR).
We've solved the issue and it should be fixed with the next release of Gala.

Issue: https://github.com/elementary/gala/issues/474
Fix: https://github.com/elementary/gala/pull/481

Update: A new version of Gala was released which should include the fix:
Version: 0.3.2~r690+pkg45~ubuntu5.0.1

Use Eddy (the recommended, graphical, elementary way)

Read this other answer about using Eddy, which can be installed in AppCentre.

Use gdebi-cli

sudo gdebi package.deb

Use gdebi GUI

sudo apt install gdebi

Then open the package using gdebi

Use apt (the proper cli way)

sudo apt install ./package.deb

Use dpkg (the way that doesn't resolve dependencies)

sudo dpkg -i package.deb
sudo apt install -f

Note that attempting to install a .deb that is inside an .iso can cause errors, so you may want to copy it to your downloads folder.


I was running Elementary 5 in VirtualBox 6 (upgraded from 5) and the GUI stopped working.

Reinstalling elementary-desktop as suggested by @Jeroen using

sudo apt install --reinstall elementary-desktop

did not work for me, but this did:

sudo apt purge elementary-desktop
sudo apt autoremove
sudo apt install elementary-desktop

I'm sure the autoremove isn't necessary. I did it to be extra sure that everything was reinstalled properly.


Revert to default color scheme in Pantheon-Terminal

You can reset terminal palette to default with dconf or via the command line:

gsettings reset org.pantheon.terminal.settings palette

To set background transparency you can change the background key at the same path. Its last value is between 1 (no transparency) and 0 (full transparency)

See Where are dircolors defined for pantheon terminal? as well


I had the same issue. It seems the system tries to go into suspend at around 15-20 minutes, but fails, and keyboard and mouse are non-responsive. Power button will not wake up. Wake on LAN will not work. Hard reset is required.

For now I disabled suspend. Must be done in the terminal as per this post: elementary OS Juno beta goes to sleep when it is not supposed to


I see a few errors. The important one is that it looks like you have some broken package lists files. In order to fix it, an option is to clear all files and recreate them again. To remove them you can execute into terminal

sudo rm -rf /var/lib/apt/lists/*

it will remove all package files and directories, it is important to have an asterick (*) at the end of the line in order to keep the directory.

After doing this, use sudo apt update in order to get the files again. Post a comment if you have any errors after doing this.

There are some other errors - a few of your repositories in your lists are not signed (log file from the other comment), you better remove them from your lists, because they do not work like this and spotify and opera never will be updated.


I also had this question when I first tried to fix bugs. And really the answer I've found is: It depends on what you're trying to fix. Not every part of elementary OS is compiled the same way and most of the time each project will have files HACKING or INSTALL with information about this. In general this is what I've found:

Standalone applications

This may me the most common case, and applies when dealing with applications like Videos, Terminal or Scratch, you compile by using the procedure found on the HACKING or the INSTALL file of the project, which is usually (but not always) something like

mkdir build
cd build/
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
make

Then you can run the executable created on the build directory.

Switchboard plugs

These are special because they are developed as shared libraries loaded by Switchboard at runtime, so the output of the build is an .so file and not really an executable.

For this what I do is install the development version of the plug directly to my system by calling sudo make install after compiling as before, then call Switchboard either from the terminal or from the Dock.

If I ever mess up and want the stable version of the plug back I will reinstall it using apt-get.


Yes, you can set the scaling factor in the system settings.

Open the settings, click on "Displays" and you'll find the scaling factor at the bottom.

Just a little note, this feature has been added just recently, so you might want to update your system if the option isn't there on your system.


Elementary OS doesn't recognize my partitions

What are you using for your partitions???

NTFS?

EXT 2, 3 or 4?

JFS?

XFS?

ReiserFS?

Also, what is your install?   Is it UEFI?    Also, your sentence is confusing as heck.   Are you trying to say:

1) my computer came with Ubuntu originally

2) I installed Windows 8.

3)  Didn't like Windows 8, so deleted it and installed Windows 7.

???????????????????????????????

Do this test: grab/download another Linux OS, and see if its installer recognizes your current partitions.  Hint:  download debian live 8.5 or fedora 24/centOS 7, put it on a USB (via dd command), and see if they recognize your partitions as they actually now exist.  Heck, this test may be even better: download and put the latest Gparted Live on a CD (or USB), fire it up, and see if it recognizes the partitions on that hard drive.   Elementary Loki's installer is the one used by a lot of Linux distros.  If it is not seeing your partitions, I am not optimistic.   And if Gaprted Live cannot see those partitions, well, then, from what I and a few others have seen, your only recourse is going to be dd-ing that whole drive.   Or, you could, like mentioned above, just stick to what's on it right now.  Windows and Ubuntu??...meh, wipe that crapper-stuff off for good and make that HD sing with Loki or Debian or Fedora or....... ;-)


How to remove color tags in pantheon-files?

There isn't a way of removing the color-tag plugin using the UI I am afraid. One way removing it would be to move the file /usr/lib/x86_64-linux-gnu/io.elementary.files/plugins/core/pantheon-files-ctag.plug into a new subfolder of /usr/lib/x86_64-linux-gnu/io.elementary.files/plugins called e.g. disabled.  You would need to open Files as administrator to do this.  You may find the plug reappearing if you update Files and it definitely will if you reinstall. A way of disabling unwanted plugins with a significant overhead might be a feature you want to request at https://github.com/elementary/files/issues


The quality of the image is a nightmare. Prepare bootable usb stick using newest elementary OS iso and balena etcher program instead of Rufus or any other software.


The solution you tried is for Intel displays, hence "Driver 'Intel'", you have Nvidia. Your login loop was a result of forcing X-windows to run the Intel driver.

Have you tried installing the proprietary Nvidia drivers. You can install them by running " Software Updater " from the applications menu, after it has checked for updates click the "settings" button, click the "Additional Drivers" tab.

After you have enabled the Nvidia driver then you can install nvidia-settings from the software centre that will add an application for controlling different aspects of your graphics card.


not sure if this would help but try to boot from a usb using "try elementary" and install skype and check if this issue occured

What is the recommended way to upgrade elementary OS 0.3 Freya to 0.4 Loki?

There continues to be no officially supported way to upgrade between version of elementary OS. This is due to the installer being a patched Ubuntu/Debian installer with no custom elementary support for upgrades, only detection (which I believe has been upstreamed).

Clean installation is the recommended method, this creates a new working environment and removes any config conflicts commonly encountered when keeping an entire home partition.

Upgrading though the update manager is not even possible, the update managers vary between these versions and this will never be made available. Any upgrade offer you see there is for the Ubuntu backend, not elementary OS.

Upgrade from installation media works much like installing cleanly does, only you leave your data on the disk as well as making a backup. This is untested and results will vary significantly. If you experience any issues, the likely response will be "does this happen on a clean install?"

  Back up everything
  Make some Loki installation media.
  Boot from the install disk and select the "upgrade" option.

Source: Me, I wrote most of the installation guide.


Ok, apparently after looking for some specs on the ethernet controller, some questions about similar motherboards on hardware forums and then some questions on the Ubuntu forums, I could narrow down the issue to the "forcedeth" driver, attributed to the nVidia nForce part of my motherboard (I assume it is some sort of I/O controller, as it also controls onboard audio, hard drives and whatnot). [EDIT: This seems to be a problem on most, if not all, ASRock motherboards running AM3+ CPUs, so if thats your case, the following solution might work out for you.]

Here is the solution that worked for me:
Booting into Recovery mode through GRUB.
Then on the recovery options, I had to select GRUB to change my system from "read-only" to "read-write".
Then I went on ROOT and did the following commands:

# rmmod forcedeth
# modprobe forcedeth msi=0 msix=0
# exit

And Ethernet is now working.

But, that only worked until I rebooted, so after a couple of hours looking into articles on my phone, I reached the following solution to make it so ethernet is working every time (also, I was having issues shutting down/restarting, those were fixed too).

Insert the following on terminal:

echo "options forcedeth msi=0 msix=0" | sudo tee /etc/modprobe.d/forcedeth_options.conf

Insert your password, and then

sudo update-initramfs -u

And bam, it is working.

So after trying everything I could think of and not being able to find help from anywhere I decided to install Linux Mint on a separate partition.
To my surprise Mint recognised all the screens no problem but encountered an error when trying to activate the third screen from the display settings. Again, I think the Dell Family Card just doesn’t have enough juice but I’m a tech noob so don’t quote me.
I configured it the way I wanted it, TV as the main screen and laptop monitor as the second and it worked great.
Swapped over to Elementary and surprisingly whatever the issue was, installing Linux Mint fixed it. There’s a bug somewhere it would seem within Elementary but Mint doesn’t have the bug.
If others are stuck with the same issue and another install is an option I would do it, get your setup working as you wish then delete the OS you don’t want.


Ubuntu maintains the Firefox package that elementary OS uses (both in apt install and in the AppCenter). Ubuntu is pretty good at keeping it up to date.

In this case 49.0.1 is only an update for Windows, so it shouldn't be of much importance. But you can download the binary and install it over your old release if you want.


There is no regional restriction for downloading elementary OS and you can download elementary OS for free by typing in $0 in the "custom amount" field, you don't need to donate every time (although it's greatly appreciated, thank you very much).

That being said, the download doesn't start for me either. I'd assume there are some technical problems with elementary's download servers right now and this will be fixed as fast as possible.

edit: The web team worked on this issue and the download should be back up without problems (works again for me, at least).


How can I enable alt-spacebar window menu?

Try disabling Alt-Spacebar as a hotkey for toggling maximized or any other entry, this should revert Alt-Space behavior to what you are accustomed to.

By default for me Alt-Spacebar was mapped to Next Keyboard Layout in Keyboard > Universal Access, by disabling this the window menu took over properly.


Can't do dualboot with Windows 10, options missing

You're booting elementary OS in BIOS/MBR/Legacy mode, which allows only up to 4 primary partitions per disk drive. Booting in EFI/UEFI will allow you to install both OSes in UEFI mode, but you need to recreate the disk's partition table and use the GPT one for this to work, because GPT or GUID Partition Table supports up to 128 primary partitions.If Windows is installed in Legacy mode, you'll have to reinstall both OSes. If your machine doesn't support UEFI/EFI, you'll have to fit in 4 parts max. Good luck!


How to type in Hangul(Korean Alphabet) in elementary OS Juno?

Since this is the first result when searching for "korean keyboard elemntary os", I would like to add this answer, as Hasan commented, as well as for my own future reference.
My use case is: I have a US QWERTY keyboard using elementary OS 5.1.7 Hera and I want to type in 한굴.

Go to Keyboard Settings (CMD + SPACE + keyboard)

Go to "Input Method" tab (enable it if not yet enabled) and click the bottom  left plus (+) sign and type "hangul" then click "Add Engine"

Configure input method to use ibus by default (see also https://elementaryos.stackexchange.com/a/18660)

# open terminal (CMD + t)
im-config

# in GUI
# click Ok
# click Yes
# select ibus
# click Ok
# click Ok

reboot

Try typing in 한굴 by toggling via the Right Alt key. If that doesn't work try Shift + Space.

(I found out about the right alt key in the Layout tab of the keyboard settings, there is no need to set Korean keyboard in Layout, just in Input Method).


XPS 13 (9350) wifi issue in Loki (but not in Ubuntu 16.04)

After several hours trying to figure this out, switching kernels, drivers, etc. I just found the solution!

sudo apt-get purge bcmwl-kernel-source
reboot

This worked for me and now i have Wi-fi :).


Yes that is typical. That is the way the login screen is setup. I use the arrow keys to switch between accounts.

I'm currently making a list of small things like this that need tweaked to give Elementary OS more polish. It's just the way it is for now.


You can view and submit bug reports here. I recommend searching the submitted reports before submitting a new one, because your issue might already have been documented.


there is a bug in the latest kernel

this will fix it for you

sudo modprobe -r peaq_wmi

sudo modprobe -r eeepc_wmi


Well, the installation worked once I opted to manually choose my partitions and changed the boot loader to my swap partition rather than /dev/sda. This seems to be a problem facing Ubuntu users in general: https://askubuntu.com/questions/459620/unable-to-install-grub-in-dev-sda-when-installing-grub


It's not in the appcenter or in synaptic, which is a gui for all the sudo apt-get commands. It is on the realVNC website.

The viewer: https://www.realvnc.com/download/viewer/

The server: https://www.realvnc.com/download/vnc/

Download the .deb files. If you just want a client that connects to a display on another pc then just get the viewer. If you want to screen share into your elementary machine then get the server too.

I'd install these with gdebi. It will look for any software that RealVNC is dependent on and install it as well. You can get gdebi from the appcenter or just run these commands in the terminal after downloading the files:

sudo apt-get install gdebi

cd Downloads

sudo gdebi name_of_realvnc_viewer.deb

sudo gdebi name_of_realvnc_server.deb

That should get it installed. There may be some setup required after install. I haven't used Realvnc in a few years. Switched to nomachine, personal preference and ease of setup, but hopefully thats enough info to get you there.


You can save as pdf. Print > Print to File actually saves the email as pdf.


Can not able to get exact value of `%u` in Vala program

You're assigning the return value to age. The return value for scanf is documented as:

  On  success,  these functions return the number of input items successfully matched and assigned; this can be fewer than provided for, or even zero, in the event of an early matching failure.

Since you're attempting to read 1 value, if the input is read successfully the return value will be 1.

Try something like

if (stdin.scanf("%u", out age) < 1)
  GLib.error("Unable to parse age");


I have checked the source you're referring to. There's no package for ubuntu 18.04 and up. It havn't been updated in 3 years. So you have to find other means to try Albert.


change username on elementary OS properly

This has been answered in another question on another StackExchange site but this is basically what you need to do:

While the user you need to modify is logged out and you're logged in as another sudoer user, do the following:

sudo usermod -l newUsername oldUsername

This changes your username but not your home folder. If you're okay with having a different home folder name from your username, you're pretty much done. Otherwise, refer to the linked answer for more details.


Thank you for sharing your code, looks good!
Took me while to look over it (needed to set up a new elementary OS virtual machine), downloaded your code, built it, and indeed got the same error when trying to install it.

That error led me to look into your post_install.py file, and noticed a typo on the first line (read more about shebang), a space had made its way where no space should be present:

After changing it to #!/usr/bin/env python3, deleting the build folder, and running the build & install commands again, the schema was parsed successfully:

And the app runs as expected:

Vala is a nice programming language, and I wish you great success in your learning process. Never hesitate to ask for help when needed, and help others when you can.


I think you (or the system) have been created a new user. The following command list all users:

sudo awk -F':' '{ print $1}' /etc/passwd
