I'm on dual boot (UEFI) with Windows10 and AppCenter installs work fine here (Installed a fresh copy yesterday)

There was an issue with the appcenter not so long ago (issue description) so you can follow these instructions.

Have you updated the OS

sudo apt update
sudo apt upgrade

Can you install via apt or apt-get?

UPDATE:
I run the upgrades and the appCenter is still working


Distorted sound quality via Bose QC35 headphones on Juno

Had some similar problem with a full bluetooth headphone.. Installed PulseEffects, did some Tweaks and it worked fine.. later on the problem came back but I think you could try that.


I found the workaround here:
https://github.com/elementary/music/issues/391

It crashes on startup if an NTFS partition is mounted.

I unmounted all network shares and it doesn't crash on startup for me anymore.


How to get integrated camera on macbook pro working

I needed to install AppleUSBVideoSupport to Elementary 5.1 (Hara) to get my camera to work on an older 2007 MacBook (2,1).  Your MacBook is much newer and can only assume it's the same issue.

This post outlines the steps.  There is a "isight-firmware-tools" package to install but before you do that, you have to grab (or download) the support file outlined in this article:

https://turanct.wordpress.com/tag/appleusbvideosupport/

NOTE: as of March 6th, in the event you want to use the iSight in Chrome, I am still working with the Chromium team to recognize the built-in iSight.  In Elementary, the default Camera app works and so does Zoom conference software.


Not able to install elementary 64 bit OE 0.3.1 freya on HP 8740w

Keep in mind that this is only a workaround!

  Rob Hartley (8ob): This is only a workaround though. The real question is why this happens in the first place. I did not receive any errors during
  installation that would suggest grub failed to configure the system properly.

Install Elementary 0.3.1 as normal (no special partitioning).Follow: elementary.io - Installation
Boot will end in grub shell. Enter:configfile (hd and press TAB. Select one and add /boot/grub/grub.cfgExample: configfile (hd0, gpt4)/boot/grub/grub.cfg
Open terminal after boot and type:cd /boot/efi/EFI/grubsudo cp grubx64.efi grubx64.efi.backup (just in case)sudo rm grubx64.efisudo cp /boot/grub/x86_64-efi/grub.efi /boot/efi/EFI/grub/grubx64.efi

Can I switch between windows of the same app using plank?

You can either scroll over the icon in plank, or right-click it for a context menu which includes open windows of the application.


Geary set up "other" provider on Asus 1000he doesnt work

A workaround to reach the hidden buttons:
Press and hold Super and drag the window at any position to move it up and reveal the hidden buttons.

You should report this bug to Yorba, the creators of Geary.


I managed to log in in the console CTRL+ALT+F1, where I run:

$ sudo apt install --reinstall elementary-desktop

Then when I reboot the os I could see the desktop and a prompt to login. However after I login, I could only see the  wallpaper. No dock or status bar were displayed.

I switched back to the console, and I installed the plank and reinstalled pantheon, pantheon-shell, reboot it. And that fixed the desktop environment. Still, some programs were lost, as Videos and Chromium, and some settings were also lost, but most of them were still kept.


Just search for Wine on the App Manager that comes default with Elementary OS

Volume key won't push volume over '100%'

So the ultimate solution to this, I was able to figure out how to assign the volume up key to a custom key combination. I used ctrl-alt-Audio Raise Volume to assign to this key. It will not give you a testing volume to show you how loud it is, but it will raise the volume past 100%. I could not figure out how to bind this to the original audio level up key.

Note I did install xbindkeys before I started, so this may have altered what you are about to see. First add a shortcut with the desired key combo through the original system settings -> keyboard -> shortcuts -> custom menu by clicking the little plus at the bottom. Call this whatever you would like.

After setting this up, open dconf Editor, and navigate to org -> settings-daemon -> plugins -> media-keys -> custom-keybindings -> custom0. For me it was custom0, but choose the index of the key binding you need to alter.

Once inside, you need to change the change the command to a version of pactl set-sink-volume 10 +10% that works for your computer. This is PACTL not PACT(one). The 10 is the device id for your audio system,  on my computer it was actually 1. The +10% should raise your volume by that percentage, and take it beyond 100% volume if you have the appropriate sound settings box checked when you run this command.

The best way to accomplish this is to test your command in terminal and then copy paste it later. So copy the command so that the whole line is highlighted as in the image below, and keep that in your clipboard.

After this, you'll need to go back into you dconf Editor window and change the command section of the shortcut for custom0. You need to paste so that when you paste, before hitting enter, there is a special character you can see following the command. Probably a representation of the '\n' newline character. Not 100% sure it's necessary, but this is what worked for me.

One of the things you'll also notice here is I bumped the % up to 750%. I found that when it executes as a key binding, it doesn't change the volume nearly as much per keystroke, so I had to adjust this to my liking.

I was also able to recover functionality of my botched default volume key through this menu in dconf Editor as well.

Hope this helps someone out there


Lock screen on corner action (with timeout)

You can try and play with xbacklight.
Not sure if it's already installed in Elementary.

sudo apt install xbacklight

Add a custom command to your desired corner. Something like:

xbacklight -dec 100 -time 500

This should do the trick.
I can't test it atm, but it should work. If you have any issues, just check xbacklight manual #man xbacklight.


eOS Loki on Chromebook wont start after suspend

AFAIK this is about the kernel issues. In some devices (Chromebooks), a newer kernel will solve the problem, but others no.
I guess you are using BOOT_STUB or full rom firmware. Changing it to RW_LEGACY firmware may help.
Here are some links about this problem:

Is a known issue on the kernel

https://bugs.launchpad.net/ubuntu/+source/kernel-package/+bug/1789252

You have three options:

Demand a good driver for the manufacturer (Lenovo/Elan)
Wait for the kernel devs to release one
Help the devs (or become one) to release the driver

Imagine a Windows without drivers, what you could do. Here at least you have people working in the solution to put it on the kernel, I suggest you to help them at least giving them info and logs if they require


This suggestion is periodically raised but is (so far) regarded as contrary to elementaryos design policy I am afraid.  See for example https://github.com/elementary/files/issues/438

Elementary native apps are intended to open quickly enough to make a preview unnecessary as the delay in generating the preview would be comparable with the delay in opening the app. Native apps are intended be as simple as possible.  In most cases the combination of file name and thumbnail (which can be as large as 256px at maximum zoom) is enough to identify the contents of the file.


Should I use the 32-bit or 64-bit system on a low-end laptop?

It is recommended that at 4GB of RAM and above, users use the 64-bit version, assuming they have a 64-bit capable CPU. You may, however, see a slight performance improvement by using the 32-bit version with PAE (included by default), as it uses slightly less memory.


Please don't follow random internet instructions, especially when they're a couple of years old. The instructions you followed were published on August 20th, 2013. They are likely pointing to what is now an out of date driver, and will have been tested on elementary OS 0.2 Luna, since Freya wasn't released until April 2014.

Option 1: (Re-) Install Freya 0.3.1

Freya 0.3.1 was recently released with an upgraded graphics stack. Installing that and sticking to the drivers found in the "Additional Drivers" module is probably both the easiest and safest way. You should be able to access your hard drive and take off any files you want to keep.

Option 2: Purge the driver

Switch to the TTY using Ctrl + Alt + F1
Login with your username and password.
Uninstall the driver.

The article you linked lists the uninstall command as:

sudo ~/Downloads/NVIDIA-Linux-*-325.05.03.run --uninstall


Elementary Calendar doesn't sync with owncloud 10.0.10

You might want to post your issue here :-)

EDIT: Sorry @Hasan you are right, of course! For better clarification why I post this link and to give a more valuable answer here comes an explanation.

A fail of sync can have many reasons. In this case it maybe is a problem of the client (which in this case is the elementary calendar app), because I can sync my owncloud (10.1.0) with thunderbird lightning and I hadn't any problems beforehand. Still it can be an issue of your server configuration though. However, I am not an expert in this so thats why I posted the link above.

The link I posted above will redirect you the offical github repository of the elementary calendar app. The Github repository holds the open source code of the app and provides an issue tracker. Posting an issue there is a great help for developers, especially when a user can provide a log.

For posting an issue in an elementary repository there are some things you can do things easier for everyone:

First check if there is a similar or even the same issue already posted
If so you can give a thumb up in the error description to mark that you have exactly the same issue
Add valuable information, maybe an additional description which also triggers the issue, provide logs
If not: Try to provide a description that makes it easy for devs to recreate the problem, provide logs and a system configuration.
Be nice and patient :-)

How can i remove and prevent a trojan on freya?

Are you running wine? If so, try clearing out your virtual C drive. If you have one, it's incredibly unlikely it's anything but a Windows virus hijacking a wine installation. Linux viruses are exceptionally rare and those that do exist typically target the larger server based distributions rather than smaller desktop distributions.

I would say more than likely, you were the victim of a phishing scam. Ensure you only ever enter your bank log on information into the site if you've typed the site's URL directly into your browser and never when linked to it from another page or email. For more information, research the topic "online phishing".


When PIA is running, you can no longer access the application to connect to a different VPN. It's no longer in the notifications panel

I found a solution for this

Install PIA as seen on the site.

Then edit pia_manager.desktop

sudo nano ~/.local/share/applications/pia_manager.desktop

And alter the line Exec=/home/bats/.pia_manager/pia_manager/run.sh

So it becomes like this:

Exec=env XDG_CURRENT_DESKTOP=Unity /home/bats/.pia_manager/pia_manager/run.sh

The icon will then appear on the panel.

Go to system settings user and click on the user account settings. click on your own account (original account) en enter the new password. Change after that my own account's password to the old password of this account I used before I had the problem. logged out of the test account.The login sacreen appears. logged in with my own account with old password. Voila!

Dear elementary os developer, can this be a bug? I only chose a different password in the gui to have this problem. It seems after changing the password by using elementary os gui, i changes the unix password in terminal but somthing goes wrong.

This kind of situation is very bad for any user with a encrypted home folder.


elementary os opens tty terminal at start

You can try to resolve the problem by typing:

sudo dpkg-reconfigure lightdm

Perhaps there is a confusion between display managers. To show the current one, type:

For other solutions, you have to investigate further.


My keyboard completely freezes after halt/suspend (Loki 0.4.1). How do I fix this?

it's possibly a power management issue.

does removing the keyboard and plugging it back in resolve the issue?

As for resources I find the Arch wiki pages to be well written, some of the information needs to be changed because ubuntu uses a different folder stucture, but most of the info still applies.  https://wiki.archlinux.org/

There's also the Ubuntu manual pages. http://manpages.ubuntu.com/

Wifi down after waking up from a long suspend

This seems a rather frequent problem in ubuntu 16.04 on which Loki is based (askubuntu question: 16.04 LTS wifi connection issues) and it happened very often on my system.

You can try other answers under that askubuntu question, but for me it got less frequent (I guess) after following this answer .

What it says is:

  Get details of your PCI wireless card by running sudo lshw -class network
  Get your card model info according to the product line. For instance, as you can see in the question description it says product:
  RTL8723BE PCIe Wireless Network Adapter so the model of my card is
  RTL8723BE
  Open or create /etc/pm/config.d/config and add SUSPEND_MODULES="rtl8723be"(replace rtl8723be with your own model
  number) Then run echo "options rtl8723be fwlps=N" | sudo tee
  /etc/modprobe.d/rtl8723be.conf and reboot.

It rarely happens now and when it does I use the command service network-manager restart.

That can be associated with a shortcut key. I prefer a desktop launcher to run from Slingshot:

gedit ~/.local/share/applications/restart_wifi.desktop

with:

[Desktop Entry]
Icon=urserver
Name=Restart Wifi
Type=Application
Exec=bash -c 'service network-manager restart'
Categories=Network;


calendar app never asks for google password

Oh I got it to work. I put in my full email name@gmail.com in both the name and user section and it finally prompted me for the password. Yay!


How to access desktop on a headless Loki machine

Did you try making it run at start up, make sure you've done all of this first to ensure the service is running.

You can also try running sudo service lightdm restart after ensuring that the VNC server is running.

If you are not able to make it work, you can also look at logs:

ls ~/.local/share/xorg/
cat ~/.local/share/xorg/Xorg.1.log (or whatever recent log is called)

Also, what is the output of xrandr when VNC is running? I'm assuming at some point the virtual monitor should appear...

Is there a hotkey to switch through the windows of the current application? (as Alt + ` in Ubuntu)

I think there is no such specific shortkey - but it might not be needed if you consider the range of options available without trying to get exactly what you know on other desktops.
Especially considering the workflow:
I think Pantheon workspaces are rather intelligent in that there is no new empty workspace and any fullscreen window can get its own workspace (Super-F); use the shortkey that shows workspaces (Super-S, Super-DownArrow, those can be customized) and there you can drop windows of the same application onto the empty desktop (the + button) to have a separate workspace for them.

You achieve the main purpose if you use the multi-window application (and only that) in its own workspace and then switch windows there with Alt-Tab. If you need more than one multi-window application, use separate workspaces for each app, and switch between apps by switching workspaces (Super--Tab).
The quickest way for me is this: starting first window of my application, then Super-F to get a new workspace, and any new window of that app will stay in that particular workspace; if I need a new multi-window app, start the app, Super-F again to get a separate workspace for that and then open the second window etc. If the fullscreen window is taken out of fullscreen (again Super-F) it might go to the previous workspace but it can be easily moved as desired either by going to the workspace switcher (Super-S, Super,DownArrow) or by using the shortkeys that move windows between workspaces.

Is it better?
This may seem complicated at first, but in fact it may prove easier than what you ask: if you had the shortkey that you mention and you used more than one multi-window applications (let's say Libreoffice Writer and Evince), that shortkey would only work for the selected application; to go from LOWriter to Evince you would either use the mouse or set separate workspaces for the different apps in the first place, in which case your ubuntu shortkey is useless.
I think this is just a matter of using workspaces or not.


elementary OS installer crashed at choosing partition screen

I just bought a new Laptop (Lenovo IdeaPad 330S) and was having exactly the same problem as you. After many frustrating hours of research, I discovered that it's a compatibility issue between Linux and the laptop's default storage controller.

Basically from what I understand, Linux needs it to be in AHCI mode in order to properly access the partitions, and by default the laptop was configured for RAID (using Intel Rapid Storage).

You can change it to AHCI easily by accessing the BIOS, but since Windows 10 was installed with RAID enabled, doing so would make it unbootable. There are a few ways you can try to change it without breaking the windows installation (check this blogpost) but since it was a new laptop, I made a bootable Windows usb stick from the official ISO, formatted the drive and made a clean install after changing the storage controller settings to AHCI. Afterwards I was able to install ElementaryOS Juno without any problems.

You can read more about the dual boot problem with RAID here (check the most upvoted answer for a step by step description).

TL;DR

Get a bootable Windows USB stick and back up any data you may want to keep
Check BIOS for Storage Controller
Change it to AHCI
Boot from the Windows USB stick
Format drive with current windows installation and do a clean install
Try again to run the ElementaryOS installer


The configuration was changed from org.pantheon.cerbere to org.pantheon.desktop.cerbere:

http://bazaar.launchpad.net/~elementary-pantheon/cerbere/cerbere/revision/49

So I just modified the monitored-processes from there and I was able to disable Plank no problem.


Keybindings, specifically using the Super key in IntelliJ Idea

This is lame but most of linux distros comes with prebuilt keybindings for people who quits windows, so... that explains your problem.

Have you tried using CNTRL key instead of SUPER ?
if that doesn't work you should read this.
And change the keymaps for your use.

Another solution is to change the keymap of the system for Mac support, maybe the kernel doesnt configure that well, have you checked that? Let me know

UPDATE

So i investigate more and found this method if not try this other one.


Disk space fill up with kernel and firewall logs

This is likely caused by a firewall misconfiguration (which is what ufw is), which can be modified to run in low-logging mode with this simple command:

sudo ufw logging low

Then you will probably want to clear up some space.

1. Rotate your Logs

sudo /etc/cron.daily/logrotate

2. Remove old Logs

sudo rm -Rf /var/log/*.1 /var/log/*.gz


I had the same problem with Visual Studio Code, except that I'm using Loki, but I don't see why it won't work with Freya.

Go to /usr/share/themes/elementary/gtk-3.0 and add this inside apps.css :

.header-bar.default-decoration {
    padding-top: 2px;
    padding-bottom: 2px;
}

.header-bar.default-decoration .button.titlebutton {
    padding-top: 2px;
    padding-bottom: 2px;
}

Just play with the padding to get the desired height.

Do not forget to restart Gala, after you've edited the file.
Not sure why, but some apps such as Terminal and File Manager won't get affected.

Why is dns not working with my new Elementary Os Juno install working?

Hay How are you.

can you send a screen shot of your network settings.

settings > network > advanced >

sounds like you have IPv6 turned on > go to the ipv6 tab and change the drop down method from automatic or what ever it is to ignore > save

What is the IPv4 tab showing?

your DNS should be set to your internal GW (router) which is normally used for DNS internally and to the outside world.

the 127.0.0.0/24 subnet is usually used as an internal ported range and not for use on a network.

what the supplied resolve.conf output is telling you is that the DNS network should use the computers internal route for DNS.

Does your router use DHCP to assign an IP address, GW and DNS?

You may have a manually set IP address in your IPv4 settings then you will need to manually set a static entry for DNS and GW.

If this is the case set your router as the DNS server or change to DHCP and let your computer grab an IP range from the router.

send those screen shots and lets see what is currently setup.

""Cheers

How do i delete the elementary OS boot on my USB?

SilverWolf is correct.  As long as Elementary OS is installed on your hard drive (or SSD) you can safely reformat your installation USB drive.

One way to do this is through GNOME Disks

a. Go to AppCenter, search for GNOME Disks.
b. After GNOME Disks has installed go to
Applications -> Disk
c. You will see your drive list on the left column.
d. Select your USB disk (make sure you choose the correct disk).
e. In the middle column, click on the stop icon (square).
This next step will clear all of the data on the USB disk.  Be sure you want to proceed before continuing.
g. Click on the minus icon to the right of the stop icon.
h. Press the Delete button to delete the partition.
i. Press the plus icon, then click the Next button to continue.
j. Enter the volume name and leave the type as FAT.
k. Now click the Create button.
NOTE: With a USB disk you do not need to erase the media.
l. Finally, click the play icon to remount the device so it can be used by Elementary OS.

Your USB disk will now be blank and ready for use.
Good luck.


Dock does not switch back to primary display

I had a similar problem with using two docks when connected to external display. I wrote a small script that I have to execute each time I (dis-)connect to external display. I don't know any other solution then to restart plank. Just type in terminal:

If you did not change any settings in cerbere, plank would instantly restart with default settings ("show on primary") and should appear on the external display (if this one was automatically set as primary display).

I tried downloading elementaryos 3 times but is it ever so slow

When you click "Download elementary OS" button on the download page, there is a magnet icon near the download button. Click on that icon to get the torrent magnet link and use your a torrent downloader like uTorrent to download it.


.deb installation worked for me, and this is how I've done it:

Visited the Lazarus website, went to downloads (either 32bit or 64bit Linux), and then downloaded all three (as hinted) files that were there, and installed them via Software Center. Note that the order of my installs were:

FPC-src package
FPC package
Lazarus package

For people new to Ubuntu that don't understand why didn't we just download it directly from Software Center: Most of the packages in Software Center are outdated because 0.3 Freya is based on Ubuntu 14.04 (two years old now), and the packages in it are just as old. Packages will be refreshed when the next version of elementary OS launches, presumably based on Ubuntu 16.04.


Does elementaryOS works with hybrid graphics?

YES, the Linux kernel and elementary OS supports hybrid graphics technologies.

For your specific model you may get a black screen when you boot after installing elementary. If that happens you'd need to add nomodeset to the boot options on the grub menu. You do this by pressing e on the grub menu and then adding nomodeset in between quiet splash, like quiet nomodeset splash.

Then you'd need to install the nvidia driver from the terminal with sudo ubuntu-drivers autoinstall. Or you could also install them from AppCenter.


I had this problem also. Running

alsactl restore

fixed it for me, as suggested here: https://askubuntu.com/a/859931/405972


How can I prepare to install elementary OS before installing a new hard drive?

Go to elementary.io and download the Image file(.iso). Once it is downloaded just right click on the .iso file and windows should give you the option to burn it to dvd. You can then boot from that dvd to test out and or install elementary OS. It comes up with a very easy to follow prompt to install the OS. You may need to look elsewhere to find out how to boot the DVD though, that depends on the maker of your computer, and if it has bios or UEFI.


Are there open source app/programs to turn backlight on and off in Elementary os?

How do I access the photos on my SD card on elementary OS?

All connected media (CD, flash disk, SD) should automatically appear in this section in Files:

Try to be patient, it can theoretically take somewhere around a minute if your computer has a bad day

If it doesn't appear, chances are you're missing a driver for the SD reader. Try running lspci and look for the model of your reader. It's probably Realtech RTS#### (where # are some digits). Then search for a corresponding driver on the Realtech website.

If the correct driver isn't there, you're in a bad luck. Now you're allowed to swear and be disrespectful of those Windows-centric manufacturers that can't even provide proper drivers for their hardware.

If you're feeling adventurous, there is an issue on AskUbuntu which solved the same problem for a different model of HP Envy. You can follow the instructions there and compile the driver yourself. Which isn't exactly easy for a newcoming user, luckily there's a sort of tutorial available.


unable to login starting session failed returned error code 1

This looks like greeter is having trouble but that means your computer is booting properly.
Can you login using a different TTY?
Press Ctrl+Alt+F1 or possibly Ctrl+FN+F1 on a Macbook to access a different TTY.
You can finish your update from the command-line with sudo apt upgrade.
To reboot after finishing the updates you can run systemctl reboot.
If you still have issues it appears that many people have solved this by changing the ownership of the ~/.Xauthority file to the appropriate user.
You might have already tried this but I'll include in just in case.
You can reference the solution here and I've included it below.

Login to your user account through a different TTY by pressing Ctrl+Alt+F1 or possibly Ctrl+FN+F1 on a Macbook.

Set the permissions on the ~/.Xauthority file so that you own the file.

sudo chown $USER:$USER ~/.Xauthority

Reboot.

systemctl reboot

How can I hide the advertisement blocker button in Midori's headerbar?

You can turn off the advertisement blocker extension in preferences:

Open the gear menu
Select "Preferences"
Select the "Extensions" tab
Un-check "Advertisement blocker"


Is this your CPU? If that's the case you only have 2 cores not 4.
Otherwise update your question with your CPU model.

I doubt your laptop has it, but some computers allow to unblock the CPU to have more cores or to enable hyperthreading. Check inside the bios/firmware to see if there's such option.


This means you don't have enough permissions. You can try this:

Right click properties. Go to the more tab and make sure you are the owner. Then enable read and write access for the owner.

If you aren't the owner then it becomes a bit more complicated:

You don't care about the file and just want to delete it: Right click on an empty space -> open in -> terminal. Then type "sudo rm filename" (without the quotes)
You want to keep the file: Right click on an empty space -> open in -> terminal. Then type "sudo chown username filename" (without the quotes, replacing your username and the filename)

You should now have access or be able to give yourself access by going to the more tab in properties.

Edit:
Another way to achieve the same result would be right clicking the Files application in the dock and opening as admistrator. You should then be able to change the permissions back to normal by opening properties and accessing the more tab. Make sure you are the owner and have read and write permissions.


How can I Delete a users(not just disable)

You could try old school, text terminal approach:

deluser [options] <user>

Try man deluser first to get more information.

Certainly one should remove users while having administrator privileges, so either su - or sudo would be handy, too.


I recommend creating a new USB live using Rufus on Windows machine using a freshly downloaded ISO from the elementary website and try again.


How to revive pantheon files? Hung, reinstalled, unresponsive

Files is known to struggle with showing very large folders (with >10,000 items) in IconView.  Large, deep, git repositories are even worse since Files tries to determine the status of each subfolder based on all its children. If the folder is remote or on a slow device then it is even worse. Showing large folders in List View is much faster but the git problem remains.
If Files is closed with a tab showing such a folder then startup will be delayed as it tries to restore it.  You can turn off restoring by turning of "History" in System Settings/Security & Privacy (but that affects several apps) or with the commandline  gsettings set io.elementary.files.preferences restore-tabs false or using dconf-editor.


GRUB: Is there a way to pre-determine which OS to boot to, before the reboot?

I think you are looking for the grub-reboot command, it sets to which operating system it will reboot the next time. Someone asked a similar question here and it seems you have to configure some stuff for this to work correctly. After you do this you just type grub-reboot <entry>, if you press tab before typing the entry and it will show you the list of entries on GRUB.


When you have enabled that setting you can press

AltGr+4

to create a ₹

Just tested it myself, you do not need to restart your computer or even exit the settings window. It just works.

But I do agree that it is a bit assuming to just call the setting "Rupee on 4". Although it is rather intuitive on a Scandinavian keyboard-layout like mine, it might not be on some kind of keyboards I guess.


Just try this on your terminal:

sudo apt-get install ttf-mscorefonts-installer


To install kernel source you have to enable source repositories, that is have a deb-src line that corresponds to the main repository deb line in the /etc/apt/sources.list file. For instance,

deb http://fr.archive.ubuntu.com/ubuntu/ xenial main restricted
deb-src http://fr.archive.ubuntu.com/ubuntu/ xenial main restricted

After you can get the kernel source of the actual running kernel with

apt update
apt source linux-image-$(uname -r)


Pressing the windows key logo + L (locking the screen) resolved my issue. I'm leaving this here in case it helps others.

Update: My issue has returned and locking the screen no longer resolves my issue.

Update 2: Locking the screen resolved my issue again after waiting an hour and just using the computer normally. I'm sure it'll happen again, so I'll continue to provide feedback. I went through the same troubleshooting steps as I had done previously.


I believe you can navigate to your "Documents" folder then right click it. Select "add to bookmarks" or something similar.

Edit: Here you go

Open up your File Manager
Go to "Home"
Right click on "Documents"
Select "Bookmark"

"Documents" Should now be under "Personal" alongside your other bookmarks on the left.


Is there a countdown timer application for elementary OS?

I think you need a pomodoro App
Well there are some that are specifically made for elementary.
Tomato

Tomato App is a time management application based on the Pomodoro technique, specially developed for the elementary OS 0.3 Freya and elementary OS 0.2 Luna systems.
You can use the stable PPA now:
sudo apt-add-repository ppa:tomato-team/tomato-stable
sudo apt-get update && sudo apt-get install tomato

You can find others here.


NFS Shares from my NAS doesn't appear at startup

Try this way. Delete those three entries from nfsdb file and add instead of them these three:
Music       -fstype=nfs4,rw,soft,intr   192.168.1.5:/data/Music
Videos      -fstype=nfs4,rw,soft,intr   192.168.1.5:/data/Videos
Documents   -fstype=nfs4,rw,soft,intr   192.168.1.5:/data/Documents

One below other, probably the first one is working and other two not, because they are not below. If nfs4 will not work, change it to nfs.


I've added the Daily PPA and Appstream causes an error when trying to upgrade

As you can see there is a conflict between two packages (appstream-data-pantheon and appstream-data-pantheon-loki-stable) that both want to install a file (/usr/share/app-info/yaml/pantheon_xenial-main_amd64.yml.gz).

You can try to (in this order, preferably):

wait for the bug to be corrected :)
remove the older package if you do not need it any more

sudo apt autoremove appstream-data-pantheon-icons

choose to overwrite the selected file

sudo dpkg --install --force-overwrite /var/cache/apt/archives/appstream-data-pantheon_0.3.0-0~11~ubuntu0.4.1_all.deb

Other GTK themes:

Another gtk theme (although not satisfying the exigence of being "well-rated") - eOS-milky. Offers transparency but somewhat clunky in other respects (quasi-black color of selection which hides the black text of the file's name).
Flattastic GTK theme.
Numix GTK theme works too. Also, Numix-blue.

Considering icon themes (although that's beyond the scope of the question), they are easier to use with elementary than gtk themes, but even so most of them increase a lot the size of the panel icons (and that size is not editable). A set that doesn't do that and shows the same icon size as the default is ePapirus, from the Papirus suite.


There isn't currently a way to upgrade from one release of elementary OS to another. From the release announcement:

  elementary OS Luna users should back up their data and perform a clean install.

Upgrading to elementary OS Loki will probably require a clean install as well. Upgrade support is planned for a future version of elementary OS, though.


Webcam extremely slow in Snap. How can I fix it?

Hi can you try to turn off the Automatic Light Correction the Logitech C270 uses.

Theres a tool for configure such stuff out for Logtich cameras on Ubuntu its called guvcview

You can install it with sudo apt-get install guvcview

To get into the control panel run
'guvcview -o'

There should be a point where you can turn out Automatic Light Correction.

Installing elementary OS alongside Ubuntu 16.10

Just download iso from elementary OS and make bootable USB or CD.
Boot your computer from USB/CD and choose install elementary OS.
The you'll have an option to install elementary OS alongside other systems. Choose it and the you'll have a simple hard drive manager to make some space for elementary OS.

Finally, follow installing instructions on screen. :)


I've installed elementary many times and always had to install plex manually, but there is an easy way to remove it. First identify a file from plex, any file that is installed with plex would work. If you know where plex is installed his is easy, otherwise you may need to use find. Here is a good tutorial on find

Once you have the name run dpkg -S file to determin the name of the package that installed plex. For example:

dpkg -S /bin/cp
coreutils: /bin/cp

coreutils is the package that installed cp. So to remove it I'd run

sudo dpkg -r coreutils

Obviously, you don't want to remove coreutils, just whatever package installed plex.

This method will only work if plex was installed from a package. It won't work if plex was built from source.


A lot of laptop tools which exist on Windows doesn't exist on Linux systems. You can try something universal like in this answer


This should work:

sudo apt install software-properties-common
sudo add-apt-repository ppa:philip.scott/elementary-tweaks
sudo apt-get update
sudo apt-get install elementary-tweaks

It will add an extra icon in settings.

This can be solved by deleting your program files folder then reinstalling Opera to guarantee that all the program files are perfect and not corrupted. If this does not solve the issue, try renaming profile folders so that Opera creates new ones, and then check if it works fine. After this, you might have to remain with the new profile or try to fix the old profiles, but these two solutions should work.

“Try vs Install elementary” with live USB

most live distros only last one session. there are some images called persistent lives that allow saving your changes, but they are growingly uncommon. try option is meant to try the system before committing to install so you don't have to write your disk. if you plan on using the system on a daily basis then is time to install it. A dual boot setup us quite common and very easy to make. just make sure to pay attention to every step so you don't lose any data during install.


What is the maximum resolution supported by elementary OS?

Ack!  It was a dumb question.  It supports pretty much the same resolutions as other distributions.  I managed to install and it's running just fine.

I was thrown off by a blog post I read earlier about HiDPI screens and resolutions.


How can I identify a PPA is safe or not?

The only way to be absolutely certain is by reading the code and checking if it is not malicious.

If you can't read code or don't have the time to do so (almost no one does :p) you can verify how safe it is by:

Use a search engine to get more information about the ppa.
Check if there are articles describing the ppa (if a ppa has a lot of hype around itself, there is a good change someone did check how safe it is).
The amount of contributors. If there are a lot of different people working on a project, it gets really hard to implement malicious features (unless they work together on the malicious features of course) without getting noticed by the other contributors.

If besides all these options you still don't trust a ppa, you could install it in a virtual machine and test it there yourself. That way, the program(s) can not access your harddrive or hardware, and thus do no real damage.

But to repeat:

The only way to be absolutely certain is by reading the code and checking if it is not malicious.


I'm not aware of a screensaver package that works well with elementary OS.

Other popular screensaver options include XScreensaver and GNOME Screensaver, but I wasn't able to find much information about whether these work well with elementary. There are some reports of GNOME Screensaver messing up the lock screen shortcut.

Here's Daniel Foré, the founder of elementary, on screensavers (see this bug):

  I think the general consensus, last time it was discussed, was that it was better to just turn the display off.

  As stated before, the periodic table has nothing to do with our brand.

  I'm leaning towards this being a wont fix. Screeensavers are kind of an outdated concept, IMO.


is there a way to change the time that notifications take to disappear?

Install "dconf editor"

Change property value of:

  Desktop > ibus > panel > auto-hide-timeout


You have misconfigured your proxy.

Go to Configuration -> Network -> Proxy settings.  Change the actual value ( Automatic or 192.168.1.2) to "Direct connection to Internet"

Save new settings and restart network from terminal with the command :

sudo service network-manager restart

Try apt-get update again


Also, you can configure Zoom to quit the application when closed. That's my default mode.

Open Zoom configuration (cog icon on the main window) and Under General > Application check When closed, quit the application directly".

With this configuration, Zoom will close whenever you want to be closed. Otherwise, just minimize and keep it running (and accesible via Plank panel).


Force file explorer to open in foreground with keyboard shortcut

I managed to find a solution that works fine for me:

A convenient bash script that either launches a program or brings to front its first window. (Also had to install a little keyboard tool called xdotool, used by the script)

I then defined the bash script to be launched as a keyboard shortcut :)

Its not supported. With a jailbroken iPhone and a 20 dollar tweak it can be done with Rhythmbox. I doubt the tweak works out. 10.1 yet, and I haven't kept up with the current state of jailbreak.

I have 3 suggestions and questions for you. We need to analyze the environment before we fix and come to conclusion.

After freeze, hard reboot your machine. After that open one console, do a sudo tail -f /var/log/syslog on it continue using your machine for a while and observe when it freezes what message is shown on console window.
By any chance do you have bad sectors on your old HDD?
We also need to check if your CPU is over heating. We can do that with hddtemp utility.

How to replace wingpanel's “Applications” text with a icon in Elementary OS 5.1 Hera

Solution which removes Applications name from the panel

If you do not have vim, then install it with below command in terminal:

sudo apt install vim

Then type in terminal for example like below: (bear in mind that Nordic is a name of my theme which I am using currently, the default one is /usr/share/themes/elementary/gtk-3.0/gtk.css)

 sudo vim /usr/share/themes/Nordic/gtk-3.0/gtk.css

hit button with symbol / on a keyboard type .panel.maximized to find this section and hit enter.

hit insert to edit file

comment it out like that for example:

/** .panel.maximized {
    background-color: #000; }
 **/

and then put this into this file below the commented our fragment:

.panel.maximized > .horizontal:first-child > :first-child,
.panel.color-dark > .horizontal:first-child > :first-child {
    font-size:0px;
}

hit esc on a keyboard and then type :x and hit enter to save and exit.

Log out and log in again. Applications text will disappear.

Using the SIdeload app to install *.flatpakref files stuck at Preparing screen during installation

Same issue here, adding to this with more info;

Confirmed:

sideloader is installed
old flathub ppa removed

I'm able to install a flatpak via terminal.
This allows the app to be displayed in applications
Once installed it can be launched from applications but the application fails to run and just sits in the dock > after clicking the app in the dock it disappears.

launching from terminal:

sudo flatpak run org.libreoffice.LibreOffice
Gtk-Message: 19:31:53.802: Failed to load module "canberra-gtk-module"
Gtk-Message: 19:31:53.802: Failed to load module "canberra-gtk-module"

same with any other flatpck.

As a side note AppCentre isn't showing any flatpak apps, performing a cross check between a listed app in AppCentre and the app in flathub there are version number differences so its not the same app as in flathub.

checking many other apps in AppCentre none of them show the drop down to allow to be installed from flathub.

there may be an underlying issue connecting installing flatpak's and not seeing any in the AppCentre.

Additionally to the above ive installed "Discover" flatpak management from the AppCentre.

Attempted to install the same version of LibreOffice 6.3.3 from flathub, this has installed and is working successfully.

Using discovery works, logically there must be an issue with AppCentre and Flathub working cohesively together.

hope the additional information helps.


How is Gnome Software different to AppCenter?

I do not use AppCenter either. It's so buggy but good for update packages. When apt and synaptic works great there is no problem for me. I think there is no advantage at all, but it will be a cool tool in future. It is Ubuntu software center alternative designed according to OS design pattern. It is good to have it but without any bug.


Freya, Samsung Ativ 9, Display Resolution problems

Since elementary OS is built from Ubuntu you might want to check their wiki out.

You can set the resolutions you wish to use in your xorg.conf File or via the xrandr Command:

https://wiki.ubuntu.com/X/Config/Resolution#Resetting_an_out-of-range_resolution

Section "Monitor"
    Identifier      "External DVI"
    Modeline        "1280x1024_60.00"  108.88  1280 1360 1496 1712  1024 1025 1028 1060  -HSync +Vsync
    Option          "PreferredMode" "1280x1024_60.00"
EndSection
Section "Device"
    Identifier      "ATI Technologies, Inc. M22 [Radeon Mobility M300]"
    Driver          "ati"
    Option          "Monitor-DVI-0" "External DVI"
EndSection
Section "Screen"
    Identifier      "Primary Screen"
    Device          "ATI Technologies, Inc. M22 [Radeon Mobility M300]"
    DefaultDepth    24
    SubSection "Display"
        Depth           24
        Modes   "1280x1024" "1024x768" "640x480"
    EndSubSection
EndSection

However, the Xorg configuration is the better choice since it'll most likely be faster on boot.


Getting errors when trying to run sudo apt-get update

The elementary PPAs use the underlying Ubuntu release names rather than the elementary release name (see here).

For some reason your system is trying to fetch packages from http://ppa.launchpad.net/elementary-os/stable/ubuntu/dists/loki instead of http://ppa.launchpad.net/elementary-os/stable/ubuntu/dists/xenial (Loki is based on Ubuntu 16.04 LTS (Xenial Xerus) ). You can rectify this by modifying /etc/apt/sources.list and replacing occurrences of ubuntu/dists/loki with ubuntu/dists/xenial and then re-running sudo apt update.

Quite why this has happened I am unsure. You should file a bug report about it on Launchpad.


Can't type spanish characters in some programs

I guess Telegram expects the wrong input method. You have two ways to fix it:

Tell Telegram (and other Qt apps) to use xim
Just set QT_IM_MODULE=xim before running it

I don't know which one is better. There is a discussion in Telegram's github:

TP-Link does not provide any official drivers for Linux-based operating systems. They do have a download page for the T4U, but the kernel support is limited to 2.6.18 to 4.11. Newer kernels are not at all supported.
That said, you may be able to get by with one of the open drivers. This will be 100% dependent on the chipset in your T4u, though.
If your network adapter is using the RTL8812AU chipset, then this driver from thelinuxguy should work for you.
If you have a European model, which may use the RTL8822A chipset, then you'll need to find something that works. Unfortunately I do not have any experience with that specific chipset, so do not know where you can find a driver.


It is not possible to make opera as in Ubuntu. Because, no menu options available in elementary like File  Edit    View    Bookmarks   Widgets Tools   Help. So the only way to access the menu options is via logo at present.


You can try the solution I provided here: indicators on wingpanel

However I cannot guarantee it will solve your issue. But we can try to figure it out, what causes the issue.


Install TLP

 sudo apt install tlp

Then edit the config file - set the governor to powersave

 sudo scratch-text-editor /etc/default/tlp

Ensure the following lines are not commented and are as show below

CPU_SCALING_GOVERNOR_ON_AC=powersave
CPU_SCALING_GOVERNOR_ON_BAT=powersave

or

Try setting the CPU governor to performance. This will "lock" the CPU to max speed.

Install cpufrequtils

 sudo apt-get install cpufrequtils

Then edit pr create the following file

 sudo scratch-text-editor /etc/default/cpufrequtils

And add the following line to it

 GOVERNOR="performance"

Save and exit

Then disable Ondemand daemon to keep your settings on reboot

 sudo update-rc.d ondemand disable

Check your settings with

 cpufreq-info

If this doesn't work for you, you can try what's listed here

ping: sendmsg: No buffer space available

The error message means that you have hit a maximum value for a system parameter, most likely the /proc/sys/net/core/wmem_max value. This setting is the maximum amount "receive socket memory", but further investigation will be needed.
This generally happens when one of three things is taking place:

the network adapter is broken
the network adapter is using a driver that is not 100% supported
the entire system is stressed out because it is mining BitCoin or something like that

You can look at increasing the wmem_max value, but it is very rarely the correct solution to a problem.


signing certificate authority is not known

I think this is most likely an issue with glib-networking as reported in another related question about SSL handshakes failing.

Try doing a manual connection via the terminal next time this happens using the openssl command as shown below, then share the results.

openssl s_client -host mail.myzimbraserver.com -port 443


Minimal BASH-like line editing at startup

I managed to fix this problem by checking the Purge GRUB before reinstalling it in the GRUB option tab.


Can I run multiple instances of plank with separate settings?

Yes this is possible

Most of the elementary project has settings hard coded to a gsettings XMl file. Gsettings is a gnome daemon to handle settings and manage them.

Luckily, plank uses a separate file for storing preferences.

First change the settings of the plank which is currently running with plank --preferences. Change the position to the left or the right, because otherwise both planks will overlap.
Then create the new dock with plank -n one --preferences. The one is just a name - you can choose a different one if you wish.
Open system settings, go to applications then open the startup tab. Click on the + icon below and add the command plank -n one.
Then log out and back in, and you have set up two docks.


New important security and hardware support update

There is no need for these changes to be made within Freya, as the update is being delivered via the update manager. You should upgrade there, or the correct way to upgrade to the Xenial Hardware Enablement Stack via the command line like this:

Additionally to enable zoom in Plank:

Two files need to be edited before you can get the zoom effect, copy/paste.

sudo nano /usr/local/share/plank/themes/Default/dock.theme

Add the following in the end of the file;

ZoomEnabled=true
ZoomPercent=150

Save: [ctrl]+[o] and Exit: [ctrl]+[x]

The last file to edit is the schema file of Plank.

sudo nano /usr/share/glib-2.0/schemas/net.launchpad.plank.gschema.xml

Look for (near the end of the file).

                        false

Change false to true

Save: [ctrl]+[o] and Exit: [ctrl]+[x]

Last thing.

killall plank&& plank&
plank --preferences

Now enable Zoom effect in preferences.


Supported content types are defined in the source code found here. In other words, the only way to add additional file types to the library is to download the source code, edit it then build it myself.


Are there any IRC clients that comply with the human interface guidelines?

A good suggestion is probably the IRC client Relay currently in development by agronick and specifically aimed at elementary OS.

You can install it with:

sudo apt-get update
sudo apt-get install relay


Gdebi not installing .deb from within Files explorer

I had the same problem. For quite some time, I used another application called Eddy available on the AppCenter. However, I had some issues with dependencies.
If one doesn't have enough knowledge of dpkg and apt, I'd still suggest using 'GDebi.' I don't know why the GUI front-end gives problems in Elementary OS. I guess this is because if you open GDebi from a regular user account, it freezes since it is somehow prevented from asking sudo permissions.
My solution is to run GDebi from command line under sudo, that is
sudo  gdebi  path_to/file.deb

I never had issues with this approach.


Snap applications start extremely slowly

I've heard of similar issues with Snap apps off and on. One easy alternative is to use Flatpak apps from Flathub when apps exist in both places.

To install an app from Flathub:

Visit the app's page on Flathub
Click the Install button on the web page
Depending on your browser, Sideload may open automatically. If not, choose to open the downloaded file with Sideload.
Read and agree to the implications of installing an untrusted app from Flatpak.

If this is the first Flatpak app you've installed, it might not show up in the Applications Menu until you log out and back in—future Flatpak apps will show up instantly. You can then uninstall the snap version.

It's typically recommended to use Flatpak apps on elementary OS instead of snap because elementary has officially backed Flatpak, elementary OS supports Flatpak out of the box, and elementary developers have put significant work into making sure it's easy to install and update Flatpak apps without having to use a Terminal.


To expand on Peter's answer, many GTK+ themes (elementary included) have a dark variant which can be enabled for any GTK+ application by setting Gtk.Settings.get_default ().gtk_application_prefer_dark_theme = true;. You can find the corresponding line which the Videos app uses to toggle the dark theme here if you're interested.

As to why, it emphasises the actual content and minimises distractions from light pollution. The Gnome developer documentation has this to say:

  Some applications benefit from minimizing the amount of light pollution that interferes with the content. Good candidates for dark themes are photo and video editors that make the actual content get all the attention and minimize the distraction of the chrome.
  Dark themes should not be used for documents, where large spaces are white/light and the dark chrome creates too much contrast (web browser, text editor...).


Open pantheon terminal with starting command

With io.elementary.terminal, which seems to be the new name, you might be able to do this using the -e flag. I've done something very similar with xfce4-terminal -e before, maybe that helps when looking for examples around the web. You can find this option in the manpage.


Default music player in system tray icon?

I'd suggest you follow my advice and pick another application than Music. Lollypop is a good example.

Usually it's very easy to choose another music player.

Open System Settings
Click at Applications
Change default Music Player

Anyway the app volume settings shows in tray when you click the volume icon, when you run the music app (Spotify, Lollypop, Audacity etc.). If you will run the Spotify it will be there, the same for Lollypop. It disappears, when you turn off the music app. Hope my explanation is pretty clear.


Actually I found out how to do it:

The file is in ~/.config/marlin/marlin.db


This is a feature in Loki (the 2016 release). For example, "Restart" is highlighted below as I tab between the Shut Down menu options:


Wireless Mouse and keyboard combo freezing randomly for a few seconds

Try:

sudo su
echo 2 | sudo tee /sys/bus/usb/devices/*/power/autosuspend >/dev/null
echo on | sudo tee /sys/bus/usb/devices/*/power/level >/dev/null

This should disable USB-autosuspend.

Problem with the Network App on Elementary OS

I may be wrong with this train of thought but I believe there is a problem with the driver for the Atheros loading correctly. Also, if the WLAN has been spotty at best and with the App Store not able to connect you may have missed updates. Missing updates may or may not have something to do with this.

First, at a command line, I would try grabbing all updates and rebooting the machine. Open Terminal and do the following:

sudo apt-get update

sudo apt-get upgrade

Then reboot your machine and see if your WiFi (not using WICD) will connect. If not, let's try reloading the driver and restarting the wireless. Again, in Terminal, do the following:

sudo modprobe -v ath9k

Then:

sudo service network-manager restart

If your wireless still hasn't started, try one more reboot and see if it is working. Comment back with the results of the above.

Good Luck and hope this helps!!!!


How do I install Oracle Java JDK 8 on Freya?

You can install it from PPA :

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

Or download it from here then move jdk-8* to /usr/lib/jvm/jdk1.8.x then run these commands:

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.x/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.x/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.8.x/bin/javaws" 1
sudo chmod a+x /usr/bin/java
sudo chmod a+x /usr/bin/javac
sudo chmod a+x /usr/bin/javaws

x in 1.8.x means the latest version of JDK 8

Cannot add Microsoft Precision Mouse (Juno)

I figured out a way to fix this, but you need dual boot to windows.

First pair your Precision Mouse to Ubuntu. It doesnt matter if it works or not.
Then reboot to windows and pair as usual.

After that reboot to ubuntu and run this python script.
https://gist.github.com/Mygod/f390aabf53cf1406fc71166a47236ebf

You need to run it like this python3 ./script.py -s /media/carlos/90C24FB4C24F9D7A/Windows/System32/config/SYSTEM

In this case /media/carlos/90C24FB4C24F9D7A/ is pointing to my mount directory of my windows partition.

After that, the script will create a folder inside your home directory called bluetooth, with a folder with the name of the mac address of your bluetooth adapter and inside that folder there will be folders of each of your bluetooth low energy device. In my case the folder corresponding to the precision mouse is E0:52:2A:96:D2:81.

Now open a new files window as admin. You can do this by right clicking the files shortcut on your dock or on the application menu on the wingpanel.

Then navigate to /var/lib/bluetooth/AdapterAddress/. There you should find a folder with very similar name to the folder created by the script. In my case it was
E0:52:29:96:D2:81. Note that the difference is 29 instead of 2A.

Now you should be able to drag and drop the folder created by the script to the /var/lib/bluetooth/AdapterAddress/ directory, and then open the original folder that was created by ubuntu, in my case E0:52:29:96:D2:81 and copy the attributes file into the newly dragged folder.

Let me know if you don't have a windows partition and see if I can manage to make it work without Windows.

DNS Queries fail to resolve local hostnames and yet NSlookup Works

Machines on your local network don't automatically get DNS resolvable names assigned to them. You'd need to run a local DNS server or use something like pihole for that.

An easier, more immediate fix however might be to simple add an entry into your /etc/hosts file like this:

10.0.0.233      raspberrypi

that will make your pi addressable by name on this particular machine. You'd need to add a similar entry to any other machine you want to access your pi by name with.


Empty /boot/efi after fresh install of Juno

Solved

My main problem was that I was unable to access BIOS, as the normal method for my laptop didn't work (i.e. when laptop is OFF, press & hold F2 and turn it ON, keep holding F2 until bios shows up). However today after some new desperate attempts with boot-repair, I tried enter BIOS the way it's normally done on other laptops (i.e. turning it on and then press F2 like crazy) - and voila - it worked!

In the BIOS I had to do few things suggested in the link to Linux Mint forum:

Reset Secure boot to factory settings
Erase Secure boot configuration
F10 to save and reboot (this was crucial)
Enter BIOS again and select 3 EFI files from my EMMC drive (from within the ubuntu folder) and give them different descriptions:

shimx64.efi
grubx64.efi
fwupx64.efi
Note: I've used name of each file without "x64.efi" as description. But important was to have the descriptions unique.

F10 to save & final reboot.

After this I was greeted with the elementary logo :)


Uninstall flareget.

This may seem a little hard, but if you're using a third-party download manager and you're having issues downloading things, it's probably the download managers fault. Instead, try using the downloader that comes integrated into your browser of choice.


Problem when triggering the Keyboard brightness with (Fn + F9) and (Fn + F10)

Press Fn and Esc once and try to use it. Fn+Esc is a switcher which allows to use functionality. However it may be related to the hardware rather. I have no idea how to remap it, just because I am not a developer. It seems that part of the code responsible for proper working of these buttons is not properly recognizing your keyboard layout. Hard to say anything more about this.

Loki and GTX 1070: Can't choose anything but 1024x768

The proproetary GPU drivers in the base repo Elementary uses (Xenial)  are too old to properly support the 10 series cards,  try adding the graphics drivers ppa and grab nvidia-370 from there. As I recall,  xenial is locked to the 350 branch,  that branch doesn't support the 10 series line of cards,  they hadn't even been announced back then.


Just selecting gmail as your provider should just work not problem.  See below for settings.


Install Elementary OS on Intel Compute stick/low spec device onto SSD

If it supports Ubuntu then it supports Elementary OS as well (Loki is based on Xenial).

I believe that it should work properly.

However, I see that some models support only 32-bit systems -  Loki is only for 64-bit. (That nmght be the problem)

When it comes to drivers - it is possible that there are no drivers for e.g. Sound card, but in most cases there are all drivers.

As I know these intel sticks have USB ports, so maybe just try elementary live from USB and see if it works properly.

I remember that I had one of these sticks and I had problem with preinstalled windows 10 - after first start it downloaded updates that were bigger than disk space so it got stuck in 'broken mode'. I used ubuntu then to run it somehow, but finally I returned it to the store, because it had a problem that it would reset all the time as if there were some power off cuts.


Since LXLE and elementary OS are both based on the Ubuntu 18.04 LTS release you shouldn't have much in the way issues when it comes to compatibility.
Keep in mind that incompatibilities may arise for anything coupled to LXDE since Pantheon is the desktop environment used on elementary OS, though this may not be an issue for you given your server-oriented use case.
Since elementary OS is intended for desktop use, it doesn't come with as much out-of-box support for running server-side applications such as Plex Media Server.
AppCenter is meant for discovering and installing desktop applications, third-party drivers, and managing system updates.
That said, its based on Ubuntu so you can easily add support for snaps and the Snap Store just like you'd find on a stock instance of Ubuntu Desktop.
In fact, installing the Plex Media Server snap is as easy as three commands according to the Snapcraft Website's instructions.
I can't think of any known issues you'd need to be concerned with given what you've said.
If you're current system is based on Ubuntu 18.04 and is working fine then you can reasonably expect the same.
You can always test elementary OS from the installation media as a way to check.
You shouldn't need to worry about hardware compatibility issues like you had with CentOS as that would have had a different and almost certainly older kernel.
Welcome to the community, by the way.
Glad to have you hear and best of luck!

How do I make elementary OS Freya not lead me to the Grub on boot?

Change the grub boot time out.

First, open a terminal and run this command:

sudo -i scratch-text-editor /etc/default/grub

You will see something like this:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

Change the GRUB_TIMEOUT number 10 (it was line 9 for me) to any number of seconds (on my main computer I have it set to 2 seconds).

I'd advise against 0 seconds, because if you ever need to access grub, you will struggle - 2 is a good amount to chose.


Have you tried editing your /etc/systemd/system.conf file?

sudo gedit /etc/systemd/system.conf

Uncomment the #DefaultTimeoutStartSec line and set it to 5 seconds:

DefaultTimeoutStartSec=5s

Then save the file, reboot and see if it helps.

The pmi action suspend not working, so

To create keyboard shortcut key see here.

Reference here


Keep GRUB_TIMEOUT_STYLE=hidden and set the line GRUB_TIMEOUT=0.0
You need to set 0.0 instead of 0 because the grub developers wanted to avoid any problem caused by people disabling grub that way.

Juno printer error: cups missing filter warning

I know this post is a bit dated, but I experienced this issue today with the latest Elementary OS and an HP Envy 5660 printer.  I tried installing HPLIP but no joy.

What did work, however, was:

Then:

Maybe try something like Data Crow?

I was never much satisfied with the "iTunes" approach to this, wherein you get an app to "Import" some "Library" of items that you can then tag and search and comment on.

So I always ended up hacking together my own solution. Except on Haiku or OSX > 10.8, which get tagging right (in my opinion).

Poor man's solution

You can make a folder named "Tags" in your Home folder.

Then make some sub-folders within for actual tags.

And sym-link whatever you need there.
The act of sym-linking (or use TMSU) can be automated with a Contract for Files, so that "Tag this @Work" shows up in the context-menu.

That would work for a few tags, like "areas" in a GTD system, or "genres" in a music collection.

Back when I used Xfce with Thunar (the file manager), I used a Python script with a package I got out standard repos -- it displayed a simple dialog box. Let me see if I can possibly dig that up for you...

Also if the devs are reading this, Thunar had a fantastic feature -- a "Templates" folder, which populated the "New File/Folder" context-menu.


When searching for Gwenview I came across Eye of Gnome (eog).
https://wiki.gnome.org/Apps/EyeOfGnome
It doesn't have as many editing tools, but it also doesn't have most of the issues I ran into with Photos. (The file order is wrong, but you can open a slideshow. And you can open multiple images in the same window, which makes that less painful).

You can install it right away with Sideload: https://flathub.org/repo/appstream/org.gnome.eog.flatpakref

Update from Loki to Juno VS reinstalling the OS?

I think we'll be able to directly upgrade.

as you can see in the schema "Our OS section" (previous release means Loki for example)" we could do a clean install, custom, "upgrade"

however. we're still not sure if it's the new system that will be used.
as they say in this article :

System76 is aiming to ship the new installer as part of the Pop!_OS 18.04 release in April. For elementary OS, we’d love to ship it in Juno (and are working toward that goal), but we do have a backup plan to ship the existing installer if we don’t feel the new one is ready yet. So, When It’s Ready™ as you might expect.

It might be that your network manager needs restarted.

Try

How to you install Adobe Air on Loki 64bit

Ok, after much effort, I finally got this to work.  Here's how:

sudo apt-get -f install

sudo dpkg --add-architecture i386

sudo apt-get install libxt6:i386 libnspr4-0d:i386 libgtk2.0-0:i386 libstdc++6:i386 libnss3-1d:i386 libxml2:i386 libxslt1.1:i386 libcanberra-gtk-module:i386 gtk2-engines-murrine:i386

Note: the above command is similar to other tutorials, but without lib32nss-mdns:i386 as it couldn't be found.  This was a huge PIA and a lot of googling to find the answer, so the replacement can be installed with:

sudo apt-get install libnss-sss:i386

Then, as with other tutorials, create the symbolic links with:

sudo ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0 /usr/lib/libgnome-keyring.so.0

and

sudo ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0.2.0 /usr/lib/libgnome-keyring.so.0.2.0

Then finally, make the Adobe installer executable with:

sudo chmod a+x AdobeAIRInstaller.bin

Then install it:

sudo ./AdobeAIRInstaller.bin

Now, it takes some time for the dialog to show after the above command, so give it a while.  But when finished, you should see Adobe Air in your applications.

Then for completeness, delete the symbolic links with

sudo rm /usr/lib/libgnome-keyring.so.0

and

sudo rm /usr/lib/libgnome-keyring.so.0.2.0

So after all that, I tried to install Scratch 2.0 Offline (which was the whole point of the exercise) and it didn't work!  Then I changed the permissions of the .air file to full read write execute for both current user and sudo and voila, it worked!


Why on a single partition drag & drop is 'copy' instead of 'move' in Pantheon-Files?

Loki is still a new release so there are still a lot of bugs worth reporting. Even in attempting to reproduce your situation, I ran into all kinds of non-standard behavior: files that refused to drag, files that copied when they did not show a green "plus" indicator, and so on. It's possible that what you observed is a bug to file. I don't see any bugs like this filed right now.

Long story short, I was not able to replicate your issue (file, when dragged into folder at same level, creates copy instead of move). I tried several drives, formatted each with NTFS and Ext4 partitions, and dragged a text file around. Pantheon Files consistently copied between partitions and moved within a single partition, no matter the format. Without more context, we would not be able to know whether this is an issue with permissions, NTFS, its interaction with the system, etc. I'd start with comparing the permissions on the two NTFS drives and filing a bug report with screencaptured video.


How to type "ë" using shift+e? (as in US international layout Windows version)

In Linux the layouts are not exactly the same as in Windows, I think, but for English US (if that is what you need) you have English US alternative  International, English US International with dead keys, English US International Algr dead keys.
Dead keys are symbols that in order to be used have to be followed by Space; followed by other keys, they add diacritics to these keys; the dead-keys resemble the diacritics they trigger, and therefore are easy to remember: "+a=ä, ^+a= â, etc.

English US alternative  International and  English US International with dead keys seem almost identical.
", which is a dead key, followed by e gives ë

If you don't want to switch keyboards and use one that doesn't have those dead keys, you can try English US International Algr dead keys, where dead keys appear only with Altgr. There ë is done with  Altgr+Shift+r, as seen here:

As for ë made with Shift+E I have not found any English US QWERTY layout that does that.

How do I optimize my SSD with Trim in Freya?

Setting up a trim job on Freya
You can add the TRIM command to /etc/rc.local. Then this command will be executed automatically on system boot. This hardly slows the boot process down.
You can do that as follows:

Type in the terminal:
sudo -i scratch-text-editor /etc/rc.local

Above the line exit 0 in that file, you now add the TRIM command
fstrim for every automatically mounted EXT4 partition.

Note: not for partitions that aren't mounted by default! And also not for the swap partition, as that's already being trimmed automatically by the system by default, during the boot process.
Your rc.local should look like this:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
fstrim /
exit 0

If you have a separate home partition, then you add the following line as well, above exit 0:
fstrim /home
Note: if you have a separate partition for /boot/efi, don't add a trim command line for that in rc.local. It's useless, as that partition is seldom being written to. And it may even cause malfunctions.

Save the modified file and close it.

Reboot your computer.

Disable the now useless weekly trim
sudo mv -v /etc/cron.weekly/fstrim /fstrim
With that command you've transferred the script file fstrim to the root directory, thus disabling it.

The sha256sum in the Installation page is for elementaryos-5.1-stable.20191202.iso

But if you go ahead and download the new iso file, you'll get elementaryos-5.1-stable.20200204.iso, an updated one. My guess is the Installation page has not been updated yet with the new checksum.

For the new iso file, I get

Yep, the hibernate option in Power panel doesn't work indeed (checked that myself). As it was mentioned here, it's possible to hibernate your PC via sudo systemctl hibernate command, but impossible to do that via the elementary's power control panel. Long story short, after some discussion the devs have decided to remove Hibernate option from elementary OS.


Contacts app not showing in Applications

Open terminal and paste

  sudo nano /usr/share/applications/org.gnome.Contacts.desktop

Look for

  OnlyShowIn=GNOME;Unity

and add Pantheon after Unity

  OnlyShowIn=GNOME;Unity;Pantheon;

Then click ctrl+x and then y and Enter to save it.

Now search for contacts in Slingshot.


I think didn't recognize you wireless so try:
sudo lshw -c network
and find driver then google you wireless drive and install.


I'm going to answer with "No", as in I can't think of any good reason you shouldn't be able to use Nautilus or Nemo or any other file manager that you'd like.

The only thing I think you would lose by using Nautilus is that it doesn't use our Contractor API. So apps that install Contractor extensions (also known as contracts) won't be able to expose those extensions to Nautilus.

Be aware that some apps may try to make themselves the default upon installation. You can configure your default apps in System Settings > Applications


If your question deals with Microsoft Windows OS you are in the wrong place as this forum deals with elementary OS (a Gnu-Linux) distribution.

In any case if you search "batch in windows 7" (something similar to scripts in gnu-linux) in the search engine you use in your browser you will get an idea of what you are asking for.

If you have more questions refered to Windows 7 you should try:

or look for other forums with the search engine you use.


Transparency in pantheon-terminal disappears after half a second

You can edit the transparency level in Elementary Tweaks. Give that a shot, see if it sticks.


Due to US patent law, elementary is not able to freely distribute codecs for many popular media formats. You will likely need to purchase a license for the codecs from Fluendo on their website.

However, if you're in a country where you are not affected by this patent law, you can install a set of codecs provided by Canonical with the following command in Terminal:

sudo apt install ubuntu-restricted-extras

VLC is outside of US jurisdiction, so they are able to distribute codecs in accordance with French patent law.


Dell XPS 13" (9360) arriving soon, downloaded Loki - any issues / tips?

I'm working on a XPS 15 (with Skylake cpu) for a month now, Elementary OS works great even with the high DPI screen.
When I run into trouble I usually search on "ubuntu" (for example "ubuntu dell xps 13") since most of it applies to Elementary OS. You can also find a lot of information on bugs etc on the Elementary Launchpad pages: https://launchpad.net/elementary

I'm a web developer, also using projects like Node, Docker, Atom etc, and using custom ppa's works fine. I'm looking forward to Snaps, looks like that will be way easier for users and application developers.

When I was still using Elementary OS Freya (Ubuntu 14 LTS) I did run into a few support limitations in the end, but with custom ppa's you get very far. Since I switched to Loki I didn't experience support limitations.

I think users interact here, on Redit, Twitter and there might even be a Slack channel these days.
Welcome and have fun with Elementary OS.


Installing elementary OS in asus zenbook flip ux360

So it's been about 2 months since I have been using elementary OS on an Asus Zenbook Flip UX360. I will write down my experience so that it helps anyone else who is planning to buy this laptop.

Installation:

I created installation media using Rufus and it worked perfectly.
Initially, I tried to install using unetbootin but it did not work.

After Installation

Font size: Font looked tiny at first. I changed font size by using universal access menu and then choosing text size to be large. I could have also used dconf editor (org>gnome>desktop>interface)  but did not.
Gesture Support:  I used libinput-gestures.
Disable Bluetooth at startup: For some reason, Bluetooth gets started during startup (probably a 16.04 issue). I disabled it by adding rfkill block bluetooth in /etc/rc.local .
Chrome zoom: I set Chrome zoom level to 125% by default (Search for zoom in Chrome settings and you will get it).

Experience so far

It has been really good. I am in academia and this laptop is my daily driver.
Touchscreen works but not sure about tablet mode. I don't use either of those, so it is not an issue.
Battery life is less (about 6-7hours) than what I was getting with Windows 10 (about 9 hours). But still good enough for daily work.
There is a bug (not specific to elementary) where a process takes a lot of CPU at the start. It goes away after you touch the screen once.

I will add more things as I notice them. I think it will be good if there is a place where people can write down their experiences with different laptop models. This makes life easier for a new user who wants to buy a new laptop.


Dave, Elementary os is very secure, all the security updates are passed on as soon as they are released, Linux in general is more secure than windows.
But please remember to still be safe on the net, don't go to risky sites.

unable to login using standard user from GUI in elementary 5.1.3 hera

Try removing the password from terminal and logging in without entering a password from GUI.


As a workaround, you might want to try to install 4.11 from the Ubuntu mainline kernels.
You can download and install from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11.4/ the following packages:

sudo dpkg --install linux-headers-4.11.4-041104_4.11.4-041104.201706071003_all.deb \
linux-headers-4.11.4-041104-generic_4.11.4-041104.201706071003_amd64.deb \
linux-image-4.11.4-041104-generic_4.11.4-041104.201706071003_amd64.deb


Mouse pointer bounces around when using touchpad

Try this:
Go to the app called "System Settings", then go to the option "Displays" at the hardware section.
If you see a display called "Unknown Display" you can try to disable it and then click on the button Apply.
Maybe this can solve your problem.
