How to add a package to the live CD (iso)?

A lot of EFI/UEFI issues have been fixed in Elementary os 0.3.2, If you was not using this new update try it.

You shoudn't need to add anything to your iso. Is your linux installed without grub or not installed at all becose of grub ? Can you boot with super grub2 disk installed on a usb? if yes use boot repair from line usb or learn about rescatux witch is a distro able to install and fix grub.

I have performed with sucess an UEFI install or elementary OS, and an other one on external hard drive where grub failed to install but I can boot from super grub2 disk

Can't reinstall Calendar from App Center

Here on elementaryos.stackexchange.com is just a community of users with more or less experience in using elementary OS.

How to install while using my operating system

As a general rule, it is not possible to have two operating systems running natively on the same physical piece of computer hardware simultaneously. You can install two operating systems, but you have to shut one down before you can boot up (or install) the other (AKA dual-booting).
So you have two options:

Run elementary OS in a VM and you can continue using your host OS while elementary is running inside the VM. This is possible because the VM is essentially virtual hardware and elementary OS isn't interacting directly with your real hardware. But, as you've described, there are limitations to running in a VM.
Shut down your current OS and install elementary instead/as-well. You could remove your existing SSD and install elementary as the only OS, or you could attempt dual-booting. Though I don't know how well that would work with "hackintosh", so do so at your own risk.


How do I sync my google photos using the photos app?

I am not aware of any built-in way of syncing however, I would give overgrive a look they've got a 14 day trial and its $4.99 for a license. Basically integrates Google Drive into your desktop and by some parallels possibly your Google photos.


External speakers don't get listed/recognized

Try unplugging and replugging them in or try to find Linux drivers for them


Those icons are .desktop files. You could search for them and delete them manually, but before you do that, install AppEditor from the AppCenter. That should allow you to delete, or at least hide, them from the Launcher menu.


How can I disable "Middle-Click to Close" in Window Overview?

I have a trackpad with a large middle click zone.  Accidentally closing windows is the worst.

So, I disabled middle click in terminal:

xmodmap -e "pointer = 1 99 3 4 5 6 7 8 9"

This takes effect immediately.  Then if I start using a mouse, where again I want middle click to work, I run the reverse command:

xmodmap -e "pointer = 1 2 3 4 5 6 7 8 9"

You can put pointer = 1 2 3 4 5 6 7 8 9 into the file ~/.Xmodmap to setup a persistent default that will take effect when you login.

I'd LOVE to find a better fix.

Proper way of migrating from Shotwell to Photos?

In light of the lack of answer, i eventually went ahead and tried the solution described in my question.
It appears to work fine: copying the Shotwell database located at ~/.local/share/shotwell/data/photo.db in the old home directory to ~/.local/share/io.elementary.photos/data/photo.db in the new ElementaryOS home directory and then starting up Elementary Photos results in Elementary Photos finding the pictures, events, tags, etc..
You just want to make sure you start Elementary Photos a first time before doing the database copy step described above and change the settings to adjust where Elementary Photos should import pictures and whether it should automatically import pictures, in case you want to avoid adding pictures to your library that shouldn't be there. By default, Elementary Photos will scan and add everything located in your user's Pictures directory (~/Pictures).


code text editor problem in elementary os juno

I think this is the solution for your problem

Can't open a new tab or new file on scratch

  To fix this issue:

  Make sure you don't have any unsaved files in Scratch when run as root (with the sudo command). This fix will delete those files.
  Open Terminal and use root permissions to remove the directory.

  sudo rm -rf ~/.local/share/scratch-text-editor
  Open Scratch as your own user (do not use the sudo command)

Scratch is the old name of Code

With Code the command should be: sudo rm -rf ~/.local/share/io.elementary.code

About notificacion icons. Juno dropped the support of the old ayatana

While the software devs implement the new way you can have them back by...

$ sudo add-apt-repository ppa:yunnxx/elementary
$ sudo apt update
$ sudo apt install indicator-application wingpanel-indicator-ayatana

then you need to edit a file (i used nano, use any editor you want - avoiding a holy war)

$ sudo nano /etc/xdg/autostart/indicator-application.desktop

find the line

OnlyShowIn=Unity;GNOME;

and add Pantheon

OnlyShowIn=Unity;GNOME;Pantheon;

that's it, just restart X and you will have the old notification area icons


My top bar hover become blurry after changing theme

Not all of the themes you can find online support elementary OS also not all of the  ones that support the eOS are written well - so if there is no problem with the default elementary theme, usualy the reason is that the theme you use is not good for elementary OS. In this case you can address the issue to the theme developper or change the theme with a compatible one.


How to delete Elementary OS without another OS installation?

If you wish to delete everything you can achieve this by an eOS USB flash drive. Just boot your computer from the usb flash drive, choose 'Try elementary OS without installing' and use GParted application to format the drive you want to clear.


This is a bit technical, so let me know with a comment on anything you get stuck with but here goes:

Your 32 bit games might not be failing because of your driver but because 64 bit Ubuntu doesn't ship 32 bit libraries. there used to be an easy metapackage for 32 bit support called ia32-libs but for whatever reason it was removed.

To work around this go to your game's folder in terminal eg ~/games/foobar and in it type ldd foobar using the output to find the missing libraries. You can then install the 32 bit versions of them. As an example for sdl2 you'd type libsdl2.0:i386 the :i386 denoting the architecture. You could theoretically install arm libs this way but they won't run on your processor.

apt-cache search foo will probably help you alot here.


How do I install this program: libQtGui.so.4

elementary OS 0.3.2 Freya (64-bit) (Ubuntu 14.04) black screen after Update

It may be due to kernel issues. Try to boot with an older kernel from grub menu as below.

Select Advanced options for elementary os
Select the kernel which u think is suitable

If that works, you can remove the new kernel while retaining the older one. But be sure to check which kernel u currently using by

  uname -r

and try not mess with it.

To remove kernel, replace X.XX.X-XX with kernel version as below

  sudo apt purge linux-image-X.XX.X-XX-generic linux-image-extra-X.XX.X-X-generic linux-headers-X.XX.X-XX linux-headers-X.XX.X-XX-generic

Then update the grub

  sudo update-grub

Reboot ur system.


Yep, it seems you're using a different icon theme. That should be the culprit.
Change the icon back to Elementary and that should solve it.


Show new opened apps icons in Plank to the left?

As far as I can see it's not possible.
The only way I found to preserve the position of the dock items, is to set the plank alignment to left-aligned or in panel mode with items aligned to the left.

But because you want to have your apps aligned to the right, this is probably NOT the way you want it.

If you still want to try it, here is how:
Option 1:

Press Ctrl and perform a right click on the plank
Open Settings
Set alignment to left-aligned OR select panel-mode Not sure if it's called like that, because I'm using a different language
If you selected panel-mode you'll have to set the alignment of the items to left-aligned.
Now the plank should be aligned to the left and new apps don't move the apps which are already in the plank.

Option 2:

Open ~/.config/plank/dock1/settings with a text editor
Change Alignment=3 to Alignment=1 (for left-aligned) OR change  Alignment=3 to Alignment=0 (for panel mode)

If you choose panel mode, set ItemsAlignment=3 to ItemsAlignment=1

Now the plank should be aligned to the left and new apps don't move the apps which are already in the plank.

How well will Elementary OS run on a 5-yr old Acer netbook?

The System Recommendations are:
    Intel i3 or comparable dual-core 64-bit processor
    1 GB of system memory (RAM)
    15 GB of disk space
    Internet access

That being said: I run freya on a Dell Laptop from 2003. While it is slow, it's still faster than anything but LXDE.

There is also a way you can turn off animations in pantheon, which will speed up performance on older systems. That video is for Luna, but I am pretty sure it will work in Freya.


I wonder why I have always failed to add screenshot-tool ppa ? Please help

sudo apt-get update
sudo apt-get upgrade screenshot-tool
sudo add-apt-repository --remove ppa:elementary-os/daily

The installation instructions are outdated. I hope that @Ravan is going to manage to get them fixed by contacting Fabio.


How to install Tor browser on elementary OS

You need to get the Tor Browser Bundle (I'm not sure if there's a version of this in the repositories).  Extract to a convenient location, and in a terminal window execute

Shortcut to change keyboard layout doesn't work

With Alt+Space may be problems, but you can change Win+Space in System Settings (Switchboard). This combination does not fail, and works without problems.

Also you can set some other combinations that are not available from Switchboard.

Shift+Alt:

gsettings set org.pantheon.desktop.gala.keybindings switch-input-source "['<Alt>Shift_L', '<Alt>Shift_R', '<Shift>Alt_L', '<Shift>Alt_R']"

Shift+Ctrl:

gsettings set org.pantheon.desktop.gala.keybindings switch-input-source "['<Ctrl>Shift_L', '<Ctrl>>Shift_R', '<Shift>Control_L', '<Shift>Control_R']"

Caps Lock:

gsettings set org.pantheon.desktop.gala.keybindings switch-input-source "['Caps_Lock']"


System Settings (code named Switchboard) is populated using extensions (called plugs). You cannot add an arbitrary app here. A Switchboard extension must be written.

To remove the sound plug, use the command:

sudo apt remove switchboard-plug-gcc-sound

Please be aware that some system components may depend on certain plugs to provide functionality. Generally, removing default plugs is not a good idea.


Why doesn't elementary OS include an Office suite?

Current Stance

The official stance currently that they don't really need a full suite themselves, nor do they want to ship an office suite that isn't theirs. Until then, there are several third party options (see below). For my personal opinions, taking the near-ubiquitous Microsoft Office as an example, it comes with:

Word
Excel
PowerPoint
OneNote
Outlook
Publisher
Access

Each of these require individual analysis, so let's get to it.

Word

The writing application is probably the most conventional piece of software, and yet surprisingly rarely used. Simple documents are written occasionally, but not regularly enough that it was a major issue this cycle, although it has been looked at by the community (see below), the issue of compatibility (which permeates this question) will no doubt rear its ugly head.

Excel

Spreadsheets are commonly used in the workplace, but far less at home (unless you log every transaction you make, like some kind of weirdo), and elementary is definitely not targeted at the business market right now. Definitely not a priority.

PowerPoint

Another predominantly business application, and certainly something home users (if not everyone, who likes those meetings?) could do without.

OneNote

I'm not entirely sure what OneNote does, but it isn't used on any of the hundreds of machines I administer. It seems to be searchable sticky notes, and it's been opened 3 times by people so far this year, 2 were auto-launching at startup, and one was because they were curious what it did.

Outlook

I have two things to say about this:

The only use for desktop mail as far as I can tell is for reading or composing (but not sending) while offline. As we rapidly move towards always-online (I personally am very rarely without an internet connection, and certainly don't want to be composing emails during those times), they become more and more defunct.
We have Geary for this, a technically-third-party-but-built-with-elementary-in-mind piece of software.

Publisher

Yet another "business" application, back in the days where you needed to design leaflets and posters, I think this is mostly a bygone as well, plus extremely specialist, speaking of which..

Access

Access is a format for what is effectively a proprietary version of SQLite, a is a system often employed for quick-and-easy databases that rapidly move into multi-user territory that it is simply not designed for. A poorly defined piece of technology is worse that a buggy piece of technology, and most users will have no user for this. Microsoft do not even include this in most Microsoft Office versions.

Alternatives

Microsoft Office Online

Stable
Proprietary
Free +

Many people seem not to know this, but Microsoft provide free online versions that do almost as much as local ones do, notably lacking macros but not much else.

Paid upgrades and subscriptions available. Requires a Microsoft account.

Google Drive

Stable
Proprietary
Free +

Google provide a wide array of tools for working with documents, spreadsheets, and slideshows and support converting to and from Microsoft Office format, and is now being recommended by some universities. A major upside is you don't need to install or even save things, it's all just online.

Google Apps is paid and provides more features, but nothing noticeable and it doesn't bug you to upgrade.

LibreOffice

Stable
Open-Source

LibreOffice has come to be the de-facto option for open-source office tools, and for very good reason. If you want offline software, with the option of theming it's way into elementary, this is the one for you.

Kingsoft Office

Unstable
Proprietary
Free

Kingsoft Office 2013 is very Microsoft Office like, but alphas are available for native linux use and provide reasonably good compatibility, but very little elementary tie-in.

Writer

Unstable
Open-Source
Designed for elementary OS

There is a great mockup for a Writer on Deviantart by spiceofdesign that is absolutely gorgeous, and did have some code written as a third-party application, but was never official. There's been nothing done there for a couple of months, but it seems to have a significant amount of the groundwork laid.


One of my apps has a second, fuzzy icon in Plank. How can I workaround this?

Edit Oct 14th, 2015

Apparently this issue is fixed in Google Chrome v46. If you are still experiencing it, try upgrading Chrome.

To fix this issue, you can follow the steps outlined in this post:

Make a copy of the .desktop file of Google Chrome to your user's local applications folder:

cp /usr/share/applications/google-chrome.desktop ~/.local/share/applications

Open the copied .desktop file with:

scratch-text-editor ~/.local/share/applications/google-chrome.desktop

Once the file opens, paste the following line:

StartupWMClass=Google-chrome-stable

somewhere for each of the three sections in the file: [Desktop Entry], [NewWindow Shortcut Group] and [NewIncognito Shortcut Group] (for example, at the end of each section).1
Save and close the file.
Remove the Google Chrome launcher from Plank (unselect Keep in dock, if it's checked), and open the browser using the Slingshot launcher.
Select Keep in dock for the new Google Chrome icon that appears in Plank (should appear not fuzzy).

1 If you are fixing this for a different program, you can find out which WM_CLASS your window has got when you type in a terminal:

xprop WM_CLASS

and then click on the window. In case of Google Chrome the output is as follows:

WM_CLASS(STRING) = "Google-chrome-stable", "Google-chrome-stable"

For a different application it will be different, so the line to add will be  like:

    StartupWMClass=Name-of-application

After adding the line, be sure you removed the previous launcher  then start the application and right clicking on its dock icon check 'Keep in dock': just dragging & dropping the .desktop file onto the dock may still lead to a second launcher/icon appearing in the dock.

It looks like you're missing xfonts required to launch steam. You can install them with  sudo apt-get install xfonts-75dpi. Then log out, log back in, and launch steam again.

If that fails try sudo apt-get install xfonts-100dpi or sudo apt-get install xfonts-75dpi-scalable.


Turn off keyboard backlight automatically

You could script something using xprintidle. It will tell you how long it has been since some interaction has been done. Put it in a while loop with a sleep command so it only checks every 5 seconds or so.

You can set the backlight to 0 using this line:

echo "0" > /sys/class/leds/smc::kbd_backlight/brightness

So the script would look like:

#!/bin/bash

while true
do
sleep 6
if [[ $((5 * 60 * 1000)) -lt $(xprintidle) ]]; then
echo "0" > /sys/class/leds/smc::kbd_backlight/brightness
fi
done

xprintidle returns the time in milliseconds so you need to do 5 minutes times 60 seconds times 1000 milliseconds. Change the 5 to something else if you want it to run after a different number of minutes. Run this script on startup and it will check every 6 seconds if it should turn off the backlight. It will use hardly any resources. Make sure to chmod +x the script to make it executable.


How can I edit the wingpanel calendar applet?

Hard drive not seen by elementary's installer

As often happens I found a solution myself:

The problem seemed indeed in Intel Rapid Storage Technology.
If you log into Windows and disable acceleration of the hard drive with SSD, then reboot into elementary installer; the installer seem to be able to detect the laptop's hard drive. At least it was in my case.
I installed elementary into the target partition (150 GB on the pics above) on the HDD successfully.

After this you can even re-enable IRST and Windows partitions of the HD will still be browsable from elementary.

It is probably not specific to only elementary installer. Debian's installer also could not see the hard drive. Albeit I did not try installing Debian after disabling IRST.

First off, grub supports rebooting in to a specific OS, so you might want to use that instead. See https://unix.stackexchange.com/questions/43196/how-can-i-tell-grub-i-want-to-reboot-into-windows-before-i-reboot for more details.

To add an extra button would require to edit the source code of Pantheon, which would require that you manually compile Pantheon for every update. An easier way to get a 'Windows 10'-button would be to make a script that automatically configures Grub and reboots. So here's how to do that:

(CAUTION! If you don't know what this is, don't blindly copy this code!)

1. Make a script that looks like this:

#!/bin/sh

efibootmgr -n 000E
# OR
grub-reboot '<boot entry name of windows 10>'

reboot

2. Make a Windows 10.desktop file like this:

[Desktop Entry]
Type=Application
Name=Windows 10
Comment=Reboot into Windows
Exec=pkexec /path/to/script.sh

Move this file to /usr/local/share/applications to put it in the application list.

The freedesktop specification for *.desktop files

3. Make the script executable

Run this in a terminal:
chmod +x /path/to/script.sh

4. Test it.

Double click the Windows 10.desktop file and check that it works.


How can I clear the cached settings for Mail?

Well, you can see the content in the Pantheon Mail folder with:

ls .local/share/pantheon-mail/

You going to see a folder with the names of your e-mail accounts, something like my_name@example.com, so you can delete that folder with:

rm -rf .local/share/pantheon-mail/my_name@example.com

Of course you can delete completely the folder of Pantheon Mail:

rm -rf .local/share/pantheon-mail/

And that is all, i suppose that is what you wanna to do.

sudo apt-get install software-properties-gtk

adds the software & updates app into elementary so you can choose an nvidia driver the correct way.


I mean, you could just add a sleep 60 && before your shutdown -P 1, turn that into a shell script, I guess. You would have no visible timer but it should give you 60 seconds before shutting down your pc.

BTW working with a bright displays as the only light source, late at night, up until 60 seconds before literally going to bed, is seriously messing with your sleep cycle, pal ;)

I think have the same issue! I have a MacBook Pro Pro "Core i7" 2.2 17" Early 2011.
I've bought a new usb stick after seeing some usb issues during boot. I've redownloaded the Loki image, I've checked the download with sha256sum. I've flashed the usb stick with both UNetbootin and Startup Disk Creator. I've checked with Gparted that the disk has a boot flag.
Some grub experiments:

No changes: black screen
Adding the nomodeset and removing quiet splash gives a lot of [ok]'s but then a black screen with the one _.
Removing file=/cdrom/preseed/ubuntu.seed and adding live-media-path=/casper/ ignore_uuid, resulted in no errors but a fadeout to black.

Not sure what else to try...

I've been using Freya for months already on the same laptop, I'm just trying to upgrade to Loki.

Update #1: Flashed the USB stick with Freya 0.3.2, removed quiet splash added nomodeset. Worked like a charm, booted just fine...

Update #2: Flashed USB stick with Ubuntu 16.04 LTS, removed quiet splash added nomodeset. Booted with the [ok]'s, but ended in the black screen with the single _.

Update #3: I came the following docs which notes included warnings about bugs in the Startup Disk Creator. https://help.ubuntu.com/community/Installation/FromUSBStick#Install_and_run_Startup_Disk_Creator_alias_usb-creator I wasn't sure which mode I'm in (BIOS / UEFI) so I installed Virtual Box, created a virtual machine with Ubuntu 16, flashed the USB with Ubuntu 16 from there. Booted (for some reason 2 EFI boot's appeared, I tried both), removed quiet splash, added nomodeset. It booted with the [ok]'s, but ended in the black screen with the single _, again.

Update #4: Flashed USB stick with Ubuntu 16.10 (using Etcher this time). During boot 2 EFI boot's appeared, tried both. Removed quiet splash added nomodeset. Booted with the [ok]'s, but ended in the black screen with the single _.

Update #5: Using usb stick of update #4, when I removed quiet splash but didn't add nomodeset it ends with:

fb: switching to radeondrmfb from EFI VGA

Update #6: Tried adding nointremap (from: https://ubuntuforums.org/showthread.php?t=2303621&page=2&p=13547523#post13547523) resulted in same black screen with _.

Update #7: I checked my current grub parameters, from /etc/default/grub, the GRUB_CMDLINE_LINUX_DEFAULT. They where:

i8042.nomux=1 i8042.reset i915.lvds_channel_mode=2 i915.modeset=1 i915.lvds_use_ssc=0

Resulted in

fb: switching to radeondrmfb from EFI VGA

Update #8: Tried the above, with nomodeset. That ends with the black screen with _.

Update #9: Following the instructions on the following page worked!
https://orville.thebennettproject.com/articles/installing-ubuntu-14-04-lts-on-a-2011-macbook-pro/
Checking /etc/default/grub and /etc/grub.d/10_linux I figured out I've done this to get Freya working. (Really wish I had a better memory)
This does however completely disables the Radeon graphical card, which also reminds me to why I couldn't hook up a second screen.

Update #10: In an attempt to get the Radeon graphics card working I re-read the following forum post. One of the last steps it mentions is running the rEFInd install again in OS X. Doing this gave me the proper rEFInd boot screen which then included one Elementery OS option. This option also enabled the graphics card. So I could finally use external screens again and play some more demanding games.

Is there a way to manage multiple devices from a single location

Based on what you're describing, I think you're looking for classroom management software. I used to work for a school district and used LanSchool for this type of thing, but that was a Windows environment. I just did an Internet search and found Veyon is available for Linux.  That might be what you're looking for.

Noise won't import my music from my NTFS partition!

Do you know which files were not imported? This could be an issue of missing codecs and a confusing error message (for example .wma instead of .mp3 or .ogg).

You can try to install additional codecs to play some non-free media formats by installing Restricted Extras via Terminal as follows:

sudo apt-get install ubuntu-restricted-extras

If that doesn't work you could also try to install additional gstreamer plugins.

See also: How can I play .wma files with Music?


Partitioning drives before installing Loki

Create Loki Live-USB
Boot Elementary from that USB.
Open "Application" and run Gparted (There you can change your partitions)
Then click "Install Elementary"
Click on "Something Else" and click "Next".

The next screen may look rather intimidating but it is just showing your current disk layout.

Look at the image above. You will see all partitions on your disk (you can change disks in "Device for boot loader..."
 Choose free disk space there you want to install OS.
You need two partitions.
When you have found the partition with free space, click on it and press the plus symbol (+) under the disk layout. If you want to delete partition, click minus symbol.
First, swap partition. Choose disk space you want to use and create logical partition:

It's recommended to create swap around 1GB or the size of your RAM in case you want to be able to hibernate your system (not possible on some machines).

Then create / partition. Choose your free space, set size you want, when create primary partition with mount point "/" (it's means root) as Ext4 file system.

Press "OK" and then "Install now" to continue.


Which driver did you try? There's quite a few details missing here so you'll have to be a bit more descriptive. From a quick scan of AMD's closed source driver page, they ended support for 5000 series cards with 15.04. If it's the open source driver you're looking for, it should have been installed by default with Loki. Can you post the output of lspci -k | grep -EA2 'VGA|Display'?


Changed login page appears, and after I log in a black, empty screen appears

The login screen was changed after an update of pantheon-greeter and what you describe now it is the new, normal for all login screen. The empty desktop is an issue for a lot of people, including me. I have NVIDIA graphics and reinstalling the drivers helped me, but sometimes its solved by itself.


When upgrading hardware, do I need to reinstall elementary OS for hardware recognition?

The only main issue : your video graphic card. If you want to change your graphic card, do not forget to uninstall your driver.


Will installing elementary OS Juno going to wipe data on other drives?

You will have to chose the good option and take care during installation: selecting the last option in that list - the one that allows you to access and administer partitions - namely: "Something else".

There, you can select the partition you want for elementary, and it will be installed there - and only there. Nothing else will be touched, unless you decide otherwise.

Also here on elementaryos.stackexchange.

This tutorial for Luna is still valid, the installer is the same.


TL;DR: (probably because) the partition is marked hidden.

A dd-copied USB stick booted fine on a few machines I tried. But these were 5-10 year old desktop boxes with BIOS.

The elementary ISO is an ISOHYBRID, like pretty much every distro these days. That means the disk image is both a bootable CD and an MBR-partitioned hard disk; a clever hack. But looking at the partition table, it is marked type 17 (hex), or "Hidden HPFS/NTFS". Of course, that's not what the partition is, hidden or not. Apparently that was the convention for a period of time.

It also appears that the ISO was built with Debian live-build 3.0, which is now a few versions old. Debian 6 also uses the same partition type. Debian 5 was not ISOHYBRID, and had no MBR. Debian 7 and 8, and other current distros use partition type 00, which technically means "empty". That makes no sense either, but apparently it works better.

One more consistently visible effect of having a "Hidden HPFS/NTFS" partition is that the Files app or equivalent will not show it when you plug in the stick, for you to click-to-mount. But it is visible (and click-mountable) in the Gnome Disks app, for example.

Perhaps the particular BIOS/EFI you have also "honors" the partition type in the same way.

I changed that one partition type byte on the stick, and "elementary OS" appeared in the UI when I plugged it in, as you expected in your screenshots. As I mentioned earlier, it booted fine for me regardless, so I have no evidence on that aspect.

I tried to come up with a "one-liner" for you to patch the same byte so you could try it, but couldn't come up with something good. Maybe someone else might have an idea; or I could come up with a "three-liner" or "five-liner" if you really want to try.

Going forward, I have no working knowledge of the particulars of how elementary builds their distro, so it may not be as simple as "do it like this". But it seems like an issue they can track and prioritize.


There are quite a few password managers for linux. If you search on password in the App Center you'll see some good ones pop up. I use password gorilla myself. It's also cross platform (Mac and Win). As car as secure notes, what were you looking to have as far as features. There are a ton of web based ones. I use Google Keep, which can be used as a web app and act as a real application.


gnome-settings-daemon handles media key presses. Perhaps it is either being started too early or too late. Your best bet is to try and isolate the problem to this service by stopping and starting it again (without logging out and in).


What kind of printing system used by elementary OS?

You have CUPS as printing system, however you have a nice GUI to configure it in the Switchboard (System Settings) as well:


you have just installed the mysql server for client tools you could use the command line tools which are in mysql-client package and mysql workbench for GUI, you can install both packages like this sudo apt-get install mysql-client mysql-workbench.


I had a similar problem. Sound is very intermittent. Check the link below. It seems to have fixed my sound issue, for now.

How to prevent updating of a specific package?

Using CLI: (Recommended, see pastebin and note)

Keeping on hold: (suggest: use dpkg)

Apt

sudo apt-mark hold package-name

Dpkg

sudo -s
echo package-name hold | dpkg --set-selections
apt-get update

Note: Replace package-name with yours, for example, google-chrome-stable

Removing a Hold:

Apt

sudo apt-mark unhold package-name

Dpkg

sudo -s
echo package-name install | dpkg --set-selections
apt-get update

Note: This CLI method can hold/lock packages while updating through apt-get upgrade and also using software-updater.

Here my test with google-chrome-stable. You can clearly identify even chrome update is available but that is kept back.

Installing elementary OS as third dist for testing

Of course you can do it easily !
First of all, you need to create new partitions for eOS Distro (including his own swap if you have one for Mint (if both use the same swap, it's could have effect if you hibernate one and you boot the other one).

When you install eOS, or every linux distribution, by default an installation of grub is part of the linux distro installation. And grub can detect you windows, your mint and your eOS.
If you don't want to risk anything, do not install grub when you install eOS. After that, boot on your mint distribution. Then update your grub list using sudo update-grub and the new eOS will appear.

The best way to install multiple distro without risking anything between them is to use UEFI Bios and GPT partitions. If you do that, you can boot directly from the UEFI bios into your prefered partition which contains OS. But for that, you need to setup your bios as an UEFI bios and all your installation must be in GPT mode (and not MBR). If your current installation is not UEFI, this is a lot of work and risks. But for my PC, I have this installation and I can boot from UEFI bios even I destroy an OS boot, an SSD or whatever.

Advantage :
Boot faster because your boot a partition, not the GRUB Loader. (I boot directly into windows, I press F8 while my BIOS is booting to get more choices (Hackintosh/Windows 10 for me), I press F2 to setup default configuration into my UEFI bios directly.
No dependency between your loader (because there is no loader like GRUB) and your multiple OS installation. Your OS depends directly from your UEFI Bios.
You can add and remove partitions easily with no risks (don't delete the wrong partition, that's all).

If you have more question, you can ask me (my english is poor, sorry for that).


If you mean by sticky edges that windows change their appearance when they are moved close to the edge of the screen (e.g. get maximised), you can indeed disable this in elementary freya 0.3.2. The path within dconf-editor would be:

org - pantheon - desktop - gala - behavior

There you can uncheck the box named edge-tiling.


Windows sets the BIOS clock to the local time while Linuxes (so elementary OS as well) sets to UTC by default. You can set the hardware clock time standard through the command line. To change this default setting and to set the BIOS clock to local time instead of UTC, you will have to use the timedatectl command. You can check what you have set to use by:

timedatectl | grep local

The hardware clock can be queried and set with the timedatectl command. To change the hardware clock time standard to localtime, use:

timedatectl set-local-rtc 1

If you want to revert to the hardware clock being in UTC, do:

timedatectl set-local-rtc 0

(source: https://askubuntu.com/questions/169376/clock-time-is-off-on-dual-boot)


If that particular repository is not needed for anything you can delete it from /etc/apt/sources.list.d by right clicking on Files, selecting 'New Window as Administrator' then navigating to the folder previously mentioned.

Once you've done that, try sudo apt update and all should be fine. It would also be a good idea to apply any updates that are found by sudo apt upgrade or by using the App Center.

Again, this is only a solution in the event that this repository isn't needed.

Good Luck!!!


Youtube won't play in Chrome on Elementary OS Juno

I think I may be able to answer my own question.  I have the YouTube Flash Video Player extension installed.  If I change the video player from "Flash Player" to "HTML 5 Player" then videos play fine.


How to enable Wifi in elementary OS Loki?

It is likely you need to use the wapf parameter in asus-nb-wmi.  The kernel source code tells us this about wapf
/*
 * WAPF defines the behavior of the Fn+Fx wlan key
 * The significance of values is yet to be found, but
 * most of the time:
 * Bit | Bluetooth | WLAN
 *  0  | Hardware  | Hardware
 *  1  | Hardware  | Software
 *  4  | Software  | Software
 */

Using wapf=4 seems to work for most computers with hard block issues and we can apply this with
echo "options asus-nb-wmi wapf=4" | sudo tee /etc/modprobe.d/asus-nb-wmi.conf

Reboot and see if wireless works


HP 3520 has stopped working. Which print service does eOS use?

Running the following resolved it for me:

sudo apt-get install hplip --reinstall

I also removed and re-added the printer in System Settings. When selecting the driver via the add printer wizard, ts easy to miss that the right hand driver pane is scrollable so I think I may have previously been selecting the incorrect driver. There is a driver for the 3520 series further down the list


Go to terminal and type:

sudo apt install adobe-flashplugin

Now, the videos will play.

Does anyone know a program that does this?

xrandr is what you're looking for. I use it to tweak the gamma of my screen, but you can use it for all sorts of useful things.

https://wiki.archlinux.org/index.php/xrandr


Under System-Settings -> Language & Region -> Keyboard Settings -> Input Method -> (Plus Sign)
Then you can use whichever shortcut you prefer to switch between layouts/engines. Default is Ctrl+Space.
Hit it twice and you'll see the two keyboard layouts. It will auto-hide if selected as option.
You will also need the Layout changed. Under Keyboard Settings, use the Plus sign (bottom left) to add the English US, it will then bring you to a sub-list of the English US keyboards. There's multiple options for dvorak, left, right, balanced, etc.
Hope this helps!

Reduce the height of the top panel on Elementary OS Freya

You can make the panel shorter by editing your system's stylesheet. If you haven't modified your system, the file you want to edit is /usr/share/themes/elementary/gtk-3.0/apps.css. You can adjust the height of the panel by reducing the padding in the selector .composited-indicator. The current version of the stylesheet doesn't style .composited-indicator directly, so you'll have to add a line for it.

.composited-indicator is a Gtk.MenuItem so it inherits all the style properties defined in /usr/share/themes/elementary/gtk-3.0/gtk-widgets.css under the selector .menu .menuitem


Microphone, not working after a lot of work!

Somehow I managed to mess up my sound system. After a lot of searching I found that installing DKMS (sudo apt-get install dkms) and then going to the daily builds audio snapshot from the Ubuntu team https://code.launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa-daily/+packages and downloading the latest package for Ubuntu 16.04 more or less did the trick. At least it restored my audio connections. ALSA was still messed up (and I had not used alsamixer before this on this particular machine) so I reset that by running alsactl -d Finally all was restored!

I think I spent about 5 hours trying to get sound sorted and only by rebuilding the sound stack in this way have I been able to use the likes of Skype, Telegram and web based meeting systems again!

This is known issue since long time, even sometimes you just load-module reacts same way, Simple way to fix it make sure your dlna module is disabled in /etc/pulse/default.pa just comment it if not commented. Let me know if that doesn't work I'll provide default.pa file


Can't configure shared google calendar in Maya?

This feature is not available in Maya at the moment. As per your first attempt, you can only sync the application with your main calendar connected to your Google account.

How can I change the font size used by the desktop?

Quick Fix - Text Scaling

You can increase the text size of most interface elements by turning on 'Large Text' in the Universal Access settings.

Applications Menu -> System Settings -> Universal Access -> Seeing -> Large Text

The Large Text slider toggles the value of org.gnome.desktop.interface text-scaling-factor between 1.0 and 1.25.
If you want a little more control you can edit the setting directly via the command line as follows

gsettings set org.gnome.desktop.interface text-scaling-factor <value>

It should be noted that this will only scale text that relies on this setting. Some elements such as browser text etc may have their own in-app settings you will have to look for (from your question it appears you are already aware of this).

Alternative - Set DPI

An alternate method which is arguably 'better' would be to adjust your entire screens DPI setting. If you want to go down that route I suggest having a read of this to get you started or asking a new question.


I connected my earphones now my speakers do not work

open terminal and type alsactl restore then press enter, this should fix the issue


Short answer: edit /usr/share/gtksourceview-3.0/styles/solarized-dark.xml and customize it the way you want. For example, line 29, changing the value of 'base3' from #002B36 to #2B2B2B will get you the desired background color.

Long answer: take a look at Dark theme on Elemntary Code instead of “Solar Dark”


Setting up primary monitor on FHD modified Lenovo x230 on elementary OS Hera

Yes, elementary OS still uses X. I do not have the device you do, but I believe a good start would be to create the files you need, as instructed in the links you provided.

I do have a ~/.config/monitors.xml, so you can safely create it (nano ~/.config/monitors.xml), with the following contents:

<monitors version="1">
  <configuration>
    <clone>yes</clone>
    <output name="DP3">
      <vendor>SHP</vendor>
      <product>0x141f</product>

      <reflect_x>no</reflect_x>
      <reflect_y>no</reflect_y>

      <presentation>no</presentation>
      <underscanning>no</underscanning>
    </output>
  </configuration>
</monitors>

In nano, press Ctrl + O to save, followed by Ctrl + X to close it.

Running a locate xorg.conf will reveal this:

/usr/share/X11/xorg.conf.d
/usr/share/X11/xorg.conf.d/10-amdgpu.conf
/usr/share/X11/xorg.conf.d/10-nvidia.conf

/usr/share/X11/xorg.conf.d/70-wacom.conf
/usr/share/doc/xserver-xorg-video-intel-hwe-18.04/xorg.conf
/usr/share/man/man5/xorg.conf.5.gz
/usr/share/man/man5/xorg.conf.d.5.gz

So, I suggest placing the 20-fhdmod.conf file in /usr/share/X11/xorg.conf.d as well (sudo nano /usr/share/X11/xorg.conf.d/20-fhdmod.conf), containing:

Section "Device"
    Identifier  "IntelCard"
    BusID       "PCI:0:2:0"
    Driver  "intel"
    Option  "DRI" "3"

    Option  "ZaphodHeads" "DP-3"
    Option  "Virtualheads"  "0"

    #Option "kmsdev" "/dev/dri/card0"
EndSection

EDIT: Congrats on the modded X230 by the way, I plan to grab one for myself soon and mod it as well!


Can't find org>pantheon>desktop>cerbere on dconf

as far as I know there is no easy way to enable desktop icons. I recommend do use "Desktop Folder" (https://appcenter.elementary.io/com.github.spheras.desktopfolder)

However, it seems to be possible to use nautilus to get the icons back on the desktop like described here: How to enable desktop icons and right click in Elementary OS Freya?

Cheers!


Is it possible to change the color of folders?

You can, but you need to use a different file viewer - Nautilus works great.

sudo apt-get install nautilus

sudo apt-get install folder-color

You should be able to right click folders using Nautilus and select "folder color" to adjust them. Here's a screenshot of mine running Juno 5.0:

Mouse cursor size and theme not adjustable

Derek, welcome to the Elementary OS forums!

I had a similar experience with Elementary OS - Juno and a Razer Blade Stealth which is equipped with a 13.3-inch QHD display.  The resolution comes in at a whopping (3200 x 1800).  In my case, everything was super tiny.

So I used System Settings -> Universal Access -> Display to change my display text size.

Then, I went to dconf Editor (installed through AppCenter) and followed this path: org > gnome > desktop > interface > cursor-size
I switched off use default value, and doubled my cursor size in the bottom field labeled Custom value.  I saved my selection by clicking the check mark in the lower right hand side of the window.

Then I "waved" the cursor around, tried launching LibreOffice, there was no change with my cursor.  So I tried a reboot, still nothing, the cursor stubbornly remained the same [small] size.

After that experience, I turned to Gnome Tweaks (available through AppCenter).  I noticed that if I went to Appearance > Themes > Cursor and changed it from Elementary to Adwaita (default). My cursor suddenly increased in size. However, and this is where it gets interesting. Wherever the Pantheon desktop environment holds sway, my cursor will revert back to the same small size.  For example, this would include the Dock, Desktop, Window headers, etc...  So, I can not claim this is a 100% fix, but this irregularity may become something that is patched in a future update.

I hope that helps!  Good luck.


Switching wireless card from Killer 1535 to Intel 9260 on a Dell XPS 9550

Well, I went ahead and bought an Intel AX200NGW, the latest and greatest AFAIK, supporting Wi-Fi 6 ax and Bluetooth 5.1.

Just placed it in my XPS, worked out of the box right away, no drivers needed, so upgrade with no worries.


How do you make all updates install automatically?

well i think this gonna work, you can create a archive .sh with root permissions with this comand sudo touch att_sis.sh. run this command on the folder that you know. open with this command sudo nano att_sis.sh, this command will open the archive on terminal and type it this commands sudo apt-get update &&
sudo apt-get upgrade -y && sudo apt autoremove -y save and close the archive, after this in the same terminal run this command sudo chmod +x att_sis.sh after this go to config menu -> apps -> boot on the bottom will have a symbol to add program to your boot click there and select command line and type cd /home/you_user/pathToTheArchive && ./att_sis.sh. Doing this every boot of the system he will search for update, do the upgrade and remove unused packages


How to manage logins, and cash information of "Connect to Server" in ElementaryOS?

There is no in built facility to do this securely at present. But the answer to Save ssh connection pantheon-files shows how to use bookmarks to make reconnection more convenient.  Note using this method the user name and address of the server are not encrypted although the password is stored securely by the system.


Issues with exernal monitor on elementary OS Juno

I'm facting similar issues on HP Spectre x360. Loki worked great, but Juno is terrible.

In response to Unable to disable built-in monitor, I have found a way to turn it off:

Find out the display names:

xrandr | grep conn | grep -v dis

Disable the desired display:

xrandr --output <display> --off

On my machine, first command returned:

eDP-1 connected 1920x1080+0+6 (normal left inverted right x axis y axis) 293mm x 165mm
DP-1 connected primary 2560x1440+1920+0 (normal left inverted right x axis y axis) 553mm x 311mm

Then to switch off the primary laptop built-in display I simply did:

xrandr --output eDP-1 --off

I know it is not a solution but it is a start. I am intrigued by your other problems too so it is a scenario that I will be testing next.


Unfortunately, there is no way to get the old screen. Both screenshots show pantheon-greeter but in different versions - and it's not possible to install older versions on Freya.

It's sad you'd consider to leave elementary OS because of the new greeter though.


StartupWMClass is only used to group windows with the same class name. You need to look at changing the class with the exec command if the program supports gtk options.

Try running the executable with --class="Popcorn-Time". Worked for me.

How should I type elementary OS? With a lowercase e or an uppercase E?

elementary is the name used for the entire project (operating system and everything else related to it). elementary OS is just the name of the operating system, not the entire project.

elementary's team prefers typing its name with a lowercase e for consistency. So, you should always type elementary instead of Elementary (even if it's in the beginning of the sentence).

elementary's team prefers that you do not refer to elementary OS as eOS because that kind of mimics Apple's iThings, KDE's KThis and GNOME's GThat trends, which they're trying to avoid.

Bluetooth no longer works after system update

I am also using Lenovo Ideapad. Had the same issue.
Turn ON bluetooth from panel, open Terminal and copy-paste this:

rfkill unblock bluetooth

see if this works for you!


On a 2008 MacBook Pro I would suspect a failing hard drive, or at least multiple bad blocks. The 2008 should have come with a bootable DVD. You can boot from that and run Disk Utility to check the hard drive.

An SSD is a very worthwhile upgrade, as well as additional memory. I would consider these upgrades, even if the drive tests OK.


Ir you have only one drive with Windows 10, you have to resize it and leave for example 50 GB of unallocated space for Elementary. Then during the Elementary OS installation you will be able to use unallocated space to create partitions there.


Error editing connection - Did not find a connection with UUID

Open terminal and type

I would keep SD cards fat32 format. You can install gparted and format it. unmount it first than format the SD card. I do not know what you would gain from ntfs on a SD card.


'Kickstart'-style automated installation for Elementary

elementary OS currently (5.1) uses the Ubuntu Ubiquity installer. So if you have a method of producing automated installs for Ubuntu images, then this should in theory work for elementary OS images too. Though this isn't a use case the development team tests or verifies, so it's possible you may hit snags along the way.
However, the currently unreleased elementary OS 6.0 version will use a different installer, so your method probably won't work in future versions.
The usual way to do this kind of thing is to install the OS once with the desired settings and then produce a disk image from this that you can deploy to other locations.
In theory, if you delete the user you created during installation (so there are no users left), the login screen should guide you through creating a user and doing initial settings. Though I wouldn't recommend testing this on your production system! So it would be possible to create an image of elementary OS in this state to give a fresh "first run" experience.


This is controlled via a dconf setting in Loki:

gsettings set org.pantheon.desktop.cerbere monitored-processes

It should contain plank (the default is ['wingpanel', 'plank']). If plank is not listed, you can just add it:

gsettings set org.pantheon.desktop.cerbere monitored-processes "['wingpanel', 'plank']"

"Installer crashed" during install process on a dual boot UEFI Windows 8.1 64-bit laptop

Fixed it. I found a bug reported on launchpad that described my problem, it is apparently due to the installer (ubiquity) trying to open a file that it needs super user permissions for. The work around is to run the installer under sudo.

To do this I selected "Try elementary without installing". Once booted there is a shortcut with the title "Install Elementary OS", I decided to just modify this shortcut by opening a terminal (command + T) and issuing the following commands:

cd /usr/share/applications
nano ubiquity.desktop

Now scroll down and add 'sudo' to the beginning of the execution property.
Save the file. Click it (you may have to look in the application launcher to find it).

Alternatively you may be able to just open a terminal and execute sudo ubiquity, but I've not tested this.


Elemantary OS Touchpad not Working on Lenovo Ideapad 330s?

Did you tried this?

sudo apt install xserver-xorg-input-synaptics

ref: https://askubuntu.com/questions/1031940/how-to-switch-from-libinput-to-synaptics-in-ubuntu-18-04

https://www.dell.com/support/article/cl/en/clbsdt1/sln308258/precision-xps-ubuntu-general-touchpad-mouse-issue-fix?lang=en


After my install i believe i had the same problem.  When i installed my drivers a message popped up saying i needed to disable secure boot, i clicked the check mark and restarted and had a black screen with a flashing dash in the upper right corner.  What i had to do was reboot into BIOS, find the "Secure Boot" section and manually disable it, after that no more black screen for me, goodluck!


How can I upgrade from the beta to the stable version of elementary OS?

First install the package that provides add-apt-repository if it's not already installed:

sudo apt-get install software-properties-common

Next, remove elementary OS Beta PPA and replaced it with the stable PPA:

sudo add-apt-repository --remove ppa:elementary-os/daily
sudo add-apt-repository ppa:elementary-os/stable

Refresh the repository information:

sudo apt-get update

Remove the elementary OS pre-release packages:

sudo apt-get remove elementary-os-prerelease

Update/install the Linux kernel packages for the stable release:

sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-lts-xenial libgl1-mesa-glx-lts-xenial libegl1-mesa-lts-xenial

And finally upgrade the your system

sudo apt-get dist-upgrade

It's a good idea to restart your system too.


I have a Fritz!box and I didn't use the NAS, until now.

This is how I got into the NAS today.
Just click on "Entire Network".

Open the FRITZ-NAS, and a "Wifi"-icon appears.

And when you open this, a dialog box appears and you can fill in your credentials.
These are the credentials you gave in the setup of MyFritz.

After login, your files on the NAS appear.


elementary OS Freya not detecting partitions

Well, I had to reinstall windows and then get Elementary OS. It worked. If anyone tries this, make sure you back up your files so you don't lose anything important.


Some techs have pointed fingers at Dell's wifi card choice. I have had flaky wifi work when I switched to a Broadcom card from the Intel card.


Cannot boot Freya after installing alongside Windows on UEFI

Finally I found my answer.

First I installed Freya in Legacy Mode, after that I converted it to UEFI using boot repair.

After installation, I switched bios configuration to UEFI and boot in UEFI mode using Ubuntu Live (or other live media) and I do these steps:

In Ubuntu first thing we need to do is remove bios_grub partition using GParted (Just find bios_grub in Flags column in GParted and delete it).
Then type the following commands:

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

It will automatically scan systems and detect EFI.
After scanning finishes, you will see this dialog box.

Just press Recommended Repair, it will apply changes (while boot repair is working, it will ask you to run some commands in Terminal).
Now boot the successfully repaired system and enjoy elementary OS on UEFI.


Disabling networking stops the network manager which is responsible for connecting to WiFi and using Ethernet while disconnecting just disconnects from the internet. You don't need to disable networking unless you have changed configuration or something.

So if you haven't changed any networking settings they should do the same thing


I fixed the issue by using my iPhone as a personal hotspot (plugged in not wireless). Then I ran the software updater, it picked up on the Broadcom drivers. I installed it, rebooted and now my WiFi works.


Do you need to put the whole code here.

[Desktop Entry]
Version=1.0
Name=Telegram Desktop
Comment=Official desktop version of Telegram messaging app
Exec=env QT_IM_MODULE=xim /opt/Telegram/Telegram -- %u
Icon=telegram
Terminal=false
StartupWMClass=TelegramDesktop
Type=Application
Categories=Network;InstantMessaging;Qt;
MimeType=x-scheme-handler/tg;
X-Desktop-File-Install-Version=0.22

But you need to delete the TryExec line, otherwise it will not open.

But this is a palliative. Other applications running on QT will need extra settings. Try to do the following:

setxkbmap -model abnt2 -layout br -variant abnt2

And:

sudo printf 'XKBMODEL="pc105"\nXKBLAYOUT="br"\nXKBVARIANT="abnt2"\nXKBOPTIONS=""' > /etc/default/keyboard

And reboot. This should resolve permanently. Then tell me if that solved it.


How to get GNU Emacs from Flathub work on elementary OS?

You can run it with env XLIB_SKIP_ARGB_VISUALS=1 flatpak run org.gnu.emacs.
I used AppEditor to make a new menu entry.


I flashed my usb with etcher and everything went smooth. Give it a try.


How can I regain required privileges and resolve the authentication problem?

I suspect one of the following:

logind is not correctly assigning your session a logind session
you are not in the adm group
polkit is broken for some other reason

You can make sure that the second case is not causing an issue by adding your user to the adm group: sudo adduser @USERNAME@ adm (replace @USERNAME@ with your username).


How to fix broken icons in elementary os?

It looks like a broken icon set. This could be caused by a wrong translation / language pack and / or changed theme.

You can try to set the Language and Region back to default (English) or try to reinstall the desktop.

Unfortunately I do not have a elementary OS running right now, but I think it can be done with

sudo apt-get install elementary-desktop


Where do I find drivers for elementary OS?

Difficult to say without knowing what your laptop is. You could look up how compatible your laptop is with ubuntu 18.04, or install elementary on a flash drive and boot your laptop from it to see if everything works.


Disable the check box in the file manager?

I usually press an Esc key when I am working with large number of folders or files and want to make sure that I only have 1 selected.
If you press Esc, then all highlights are reset and you can select whichever file you want. You can get used to it very quickly, took me 1 file sorting session to master it :)


As already said in the comment, using a live-system suspend won't resume. The cause is the missing swap partition (or file) with an appropriate filesystem (i.e. not tmpfs). If you insist on using a live-system, you may:

config your live-system to never go to sleep and to not suspend when closing the lid, or
add another writeable drive (USB, SDHC), format with e.g. ext2 and create a swap file there.


Is it possible to search directories in slingshot?

No Slingshot does not search files or folders. It searches apps, actions, and settings


You have to download and install the 0.4.0 loki iso. There is no dist-upgrade option available from older versions.


I had this problem last night in my laptop and even tho I could solve it I don't have a technical explanation for you.

If you force install in UEFI mode it won't boot. As simple as that. I was looking for the reason behind this but all I could find was related to dual boot with Windows.

What I did was to force the installation (just click continue) and then get into my BIOS config and turn Legacy Mode on. After that your OS will boot without issues. If you don't turn Legacy Mode on the BIOS will throw a message at you saying that it couldn't find an OS.


Can I set list view as the default in Pantheon Files?

I'm planning to Install Elementary OS, I just have a few Questions

Welcome to Elementary! I can respond to a few of your questions.

PPAs: They are not enabled by default. This is alleviated by running:

sudo apt install software-properties-common python3-software-properties python-software-properties

Themes: Yes themes can be installed. Keep in mind, many elementary apps have client side decorations that don't play well with 3rd party themes. But to use themes first you need to install elementary Tweaks:

sudo add-apt-repository -y ppa:philip.scott/elementary-tweaks
sudo apt update
sudo apt install elementary-tweaks

Then create a folder called .themes in your home directory and copy the theme folder there. Use elementary Tweaks to enable the theme.

Hibernation: Yes I believe elementary has a form of hibernation (someone correct me if I am wrong on this)

Updates: There is no telling when elementary OS will shift to 17.04. Could be with the next release, Juno. But there is no information on that. elementary doesn't tend to follow regular release schedules but follow a pattern of "it will release when it's ready".

"You need 220 M on disc /boot" What I have to do?

You haven't allocated enough space for your boot partition (where the kernel goes).

and magically, in sound settings is gonna be like this.

I hope this can help.more detail about pactl command use this command:

Brightness adjustment broken - Lenovo Yoga 6 13ARE05

I recommend experimenting with some of the kernel command-line options mentioned in Ubuntu's Backlight Debugging Wiki and the ones listed in the Arch Linux Wiki's Backlight page.
If you still can't get the backlight to work, I recommend sending a bug report to Ubuntu's kernel team as outlined in Ubuntu's Backlight Debugging Wiki.
You can also try color correction with xrandr, but this is more of a hack that simulates brightness adjustment without actually controlling the backlight.
This won't save power or accurately preserve colors.


Update with terminal instead of AppCenter

elementaryOS natively supports two different packaging formats, deb packages and Flatpaks.
The system's deb packages are managed via the Aptitude package manager while Flatpaks are maintained separately with Flatpak's own command-line program.
Aptitude
Aptitude has multiple command-line interfaces available.
The new apt tool has been in Ubuntu since 14.04. apt(8) describes it thus:

The apt command is meant to be pleasant for end users and does not need
to be backward compatible like apt-get(8).

To update your system with apt is as simple as:
sudo apt update
sudo apt full-upgrade

apt-get is functionally very similar to apt, so there is nothing wrong with using it. Prashantc's answer is mostly correct, however will fall short if an updated package requires additional packages. If you are using apt-get, unless you have a specific reason for not upgrading certain packages, you should use:
sudo apt-get update
sudo apt-get dist-upgrade

The classic example, being that sudo apt-get upgrade will fail to update linux-image-generic as this needs to bring in a new dependency (i.e. linux-image-3.16.0-25-generic). dist-upgrade on the other hand handles changing dependencies with new versions of packages.
If you want something a little more interactive, you can use the Ncurses-based aptitude (installed by default), which is a frontend to apt:
sudo aptitude

Press u to update the latest package list, and then g to install updates.
You can find more information about aptitude here.
Flatpak
Flatpak is a packaging format for distributing desktop applications on Linux.
Flatpak updates are not handled by Aptitude but instead require using the flatpak command.
Flatpak keeps separate installations for each individual user while also maintaining a system-wide installation.
Individual user installations are separated from each other and also separate from the system installation.
This requires each one to be updated separately.
To update the current user's Flatpaks, use the following command.
flatpak update --user

System-wide Flatpaks are updated similarly.
sudo flatpak update --system

You can find additional information about Flatpak here.


Cannot boot to Windows 7 after dual installing Elementary

The blue screen was simply because Windows did not have the drivers installed for the mouse and keyboard I had connected (which ironically, was the Microsoft Sculpt mouse and keyboard). Once I disconnected them, I was able to boot without error. Once booted, I re-connected the mouse and keyboard, and the drivers were automatically installed. Now I can boot with and without the mouse and keyboard connected.

How to use the "Public" folder to share files between users on the same computer?

If you want one folder for all users, yes it is possible.

Before you start, please empty both the Public folders in order to prevent data loss. I will use into the command lines below user1 and user2 but you have to replace these strings with the actual usernames you want to manipulate. The Public folder's icon of the Public folder of user2 will be changed, with an arrow sign informing that this is actually a simlink. All the commands have to be typed (or copy-paste and edit the user1 and user2) into Terminal application line by line and pressing Enter. You have to do this logged in into user1 account. You will use the sudo command, which gives you administrative rights and that's why you will be asked for a password, probably only the first time you are using it.

1. create a custom group for both of the users

sudo addgroup sharedfolder

type your password and hit enter

2. add both users into the group

   sudo adduser user1 sharedfolder

   sudo adduser user2 sharedfolder

3. Change ownership of the Public folder to the new group

sudo chown user1:sharedfolder /home/user1/Public

4. Change folder permissions in order to achieve the effect:

sudo chmod 2775 /home/user1/Public

Explaining the permissions 2775 in the chmod command above:

2 – turns on the setGID bit, implying–newly created subfiles inherit
the same group as the directory, and newly created subdirectories
inherit the set GID bit of the parent directory.
7 – gives rwx permissions for owner.
7 – gives rwx permissions for group.
5 – gives rx permissions for others.

(r=read, w=write, x = execute)

5. Rremove the Public folder of user2:

sudo rm -rf /home/user2/Public

this will delete the folder with all contents and there is no easy way to return them back so you better not having there anything.

6. Navigate to user2 home folder:

cd /home/user2/

7. Create a symlink into the user2 home folder to the Public folder of user1:

sudo ln -s /home/user1/Public

Now any file you copy and paste or create into the Public folder will be with  2775 permissions and a sharedfolder group.

If you cut some file from somewere and paste it there, the permissions will not be changed and probably will be locked for the other user unless you change group (sharedfolder) and permissions (775) before you log in into the other account.
You can do this using your file manager, right click over the file or folder > Porperties > Permissions tab. See the folowing images for info, but much more easier is to copy/paste and delete source.

Bootable backup solution for elementary juno

Winston,
I used Clonezilla to maintain bootable images of both Mac and PC workstations in an enterprise environment.  Although, to achieve a bootable image I booted off a USB drive with the latest version of Clonezilla specifically created for that purpose.  Then I would save the image to an external (read: USB) drive.  Since that time, we have moved away from "monolithic" imaging and have turned to OS imaging and managed software installation (see Munki).

In the end, Clonezilla is the only product that I have encountered that will create bare metal (read: bootable) images for Windows / Mac / Linux clients.  I believe the one exception maybe Apple's new APFS file system (that replaced HFS+), but I'm sure a solution is on the way...

In my test network, I am backing up to a server through the SMB protocol and the Deja Dup Backup tool (available through AppCenter).  This is not a bootable backup but a selected backup of the critical areas of my Elementary OS (Juno) system.

I hope that helps.

mate-system-monitor won't show in Application menus, plus errors when launched in terminal

You need to realize that when you choose to install ElementaryOS, you choose Wingpanel+Plank+Gala and NOT Mate, not even Unity

when you read inside the file

/usr/share/applications/mate-system-monitor.desktop

you can find the following line

OnlyShowIn=MATE;

pretty clear

you can try removing that line but that app is part of the Mate environment not Elementary, you should go to their website to ask them how to run it outside Mate

Elementary won’t boot after successful install

For whatever reason, GRUB isn't working properly. I don't know why. I wasn't there when it was installed. So, we're going to fix it.
First, adding PPAs to eOS is a pain. It's possible, but let's just skip that step for the sake of simplicity. So we'll go ahead and download Ubuntu.
Once you've done that, you need to write the ISO to disk. You can write it to USB or DVD. If you're going to use USB, I recommend Balena Etcher.
Now, you'll need to boot the live instance of Ubuntu. As you've already installed eOS, you should know how to do this.
Once you're into the live instance, it's time to install the boot-repair PPA. Open your terminal with CTRL + ALT + T and:
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt update

You probably don't need to update, it should do that automatically. If it doesn't, then do so and then run:
sudo apt install boot-repair

Let that install and then start it from that same terminal window:
boot-repair

Just go ahead and click the recommended repair and it's almost certainly going to fix this problem. If you have a more complicated problem, or if it doesn't work, then create a summary and share the link when you're asking a new question on this site or on other sites.
As always, backup any important data. And, you don't have to use Ubuntu. You can use any distro that enables you to install boot-repair. We're only using Ubuntu for the sake of expediency.


Why are apps out of date in the App Center?

That might be because those non-curated apps come from the Ubuntu apt repositories. Elementary OS is based on a Ubuntu LTS release which in turn is based on Debian Testing at the time of the release.

At the time of writing the Elementary OS 5.x is based on Ubuntu 18.04 LTS, released in October 2018, which came with the GNOME 3.28 desktop environment and associated apps like GIMP that you mention. This may explain the outdated, non-curated apps.

Having said that: I do see the latest versions of many apps in the AppCenter however as well as outdated ones. GIMP has both 2.10.14 (current release) and the 2.8.22 versions at the time of writing. The more up-to-date one must be a Flatpak from Elementary's custom Flatpak-repositories. The flatpaks are usually up-to-date with the latest version of the developers.

The same goes for LibreOffice: the latest version is available in the AppCenter as is an older version.

If you are not seeing those up-to-date apps in the AppStore first check if you are using the latest version of Elementary OS. You need to be on Elementary OS 5.1 (Hera) to get the flatpaks in the AppCenter. If so, try updating the repositories. Right-click on the AppCenter icon and "Check for updates" or update the repositories from a terminal (Super+T):

sudo apt update

then check the AppCenter again.

You can also get flatpaks from Flathub but that is not the "official" way to get apps in Elementary OS.

Correction

I recently learned that the flatpaks that I see in the AppCenter are actually from Flathub. They got in there because I once "sideloaded" an app from Flathub.org which then adds that repository to Elementary's store.


Short answer (if this was your question): Yes it is possible to mount the user folder, system folders etc. on different disks.

First of all for a better understanding of the directory structure:

/bin : All the executable binary programs (file) required during booting, repairing, files required to run into single-user-mode, and other important, basic commands viz., cat, du, df, tar, rpm, wc, history, etc.
/boot : Holds important files during boot-up process, including Linux Kernel.
/dev : Contains device files for all the hardware devices on the machine e.g., cdrom, cpu, etc
/etc : Contains Application’s configuration files, startup, shutdown, start, stop script for every individual program.
/home : Home directory of the users. Every time a new user is created, a directory in the name of user is created within home directory which contains other directories like Desktop, Downloads, Documents, etc.
/lib : The Lib directory contains kernel modules and shared library images required to boot the system and run commands in root file system.
/lost+found : This Directory is installed during installation of Linux, useful for recovering files which may be broken due to unexpected shut-down.
/media : Temporary mount directory is created for removable devices viz., media/cdrom.
/mnt : Temporary mount directory for mounting file system.
/opt : Optional is abbreviated as opt. Contains third party application software. Viz., Java, etc.
/proc : A virtual and pseudo file-system which contains information about running process with a particular Process-id aka pid.
/root : This is the home directory of root user and should never be confused with ‘/‘
/run : This directory is the only clean solution for early-runtime-dir problem.
/sbin : Contains binary executable programs, required by System Administrator, for Maintenance. Viz., iptables, fdisk, ifconfig, swapon, reboot, etc.
/srv : Service is abbreviated as ‘srv‘. This directory contains server specific and service related files.
/sys : Modern Linux distributions include a /sys directory as a virtual filesystem, which stores and allows modification of the devices connected to the system.
/tmp :System’s Temporary Directory, Accessible by users and root. Stores temporary files for user and system, till next boot.
/usr : Contains executable binaries, documentation, source code, libraries for second level program.
/var : Stands for variable. The contents of this file is expected to grow. This directory contains log, lock, spool, mail and temp files.

During a new installation choose custom install and create a new partition with the mounting point /home on your hdd.
For the ssd choose '/' as a mounting point.

To backup and restore your programs you can follow this guide

Hope that helps a bit...


Can I use TLP for power management (Dell XPS 15 9560)

You can use TLP on elementary and it does a lot on my Inspiron machine to save battery.

sudo add-apt-repository ppa:linrunner/tlp
sudo apt update
sudo apt install tlp tlp-rdw
sudo tlp start


The easiest way is to install gnome-disk-utility
sudo apt install gnome-disk-utility
which you can run as gnome-disks in the Terminal or as "Disks" from the Applications menu. Then simply select the drive and in the "Type" selector, choose the LUKS encryption option. It will prompt for a password  (for the drive, not necessarily your login password) and you're good to go!

You'll be asked on your next reboot how you'd like to unlock/mount the drive in the future. If you'd like to compare the options, look here.


You can get rid of notifications by going to preferences (the gear icon) and unchecking "always watch for new mail." This will prevent Geary from running in the background. For good measure, you can also turn off notifications for Geary in System Settings --> Notifications --> Geary.

To remove Geary completely, open Software Center and go to Installed --> Internet --> Geary Mail and click the "remove" button.


What are the keyboard shortcuts in Photos?

The ones I could find so far:

Ctrl + A Select all
Ctrl + I Import from folder
Ctrl + S New smart album
Ctrl + F Search
Return View photo

Function keys:

F9 Toggle showing sidebar (left panel)

F11 Full screen mode

When viewing an image:

Shift Zoom out (while holding the key)
← / → Previous or next photo
Shift + ← / → Jump to previous or next photo (while zoomed in)
Space Next photo
Ctrl Swap "rotate" button to "left", and swap "flip" button to "vertically"
/ Flag photo
Ctrl + + / - Zoom in or out
[ / ] Rotate photo CCW or CW


How do I change the wallpaper through the command line?

Thanks to the Set Wallpaper Contract there already is a convenient way to set a new wallpaper: set-wallpaper

Example:

set-wallpaper ~/Downloads/coolpicture.png

set-wallpaper some-name.png will set as wallpaper the file ~/some-name.png.

If there is no such file at that location, it will create a black desktop: for example a command like set-wallpaper x.


If make uninstall does not work, your're probably out of luck. You can still search for the installed files in the jhbuild folder, and delete the from your filesystem manually.

For future installs: use sudo checkinstall instead of sudo make install, to install the files as a deb managable by your package manager.

You probably have to install checkinstall first:

sudo apt install checkinstall


The software is free and open-source, donations are optional.


Geary crashing when looking through emails

I found a temporary reprieve from this issue by disabling the 'Always show remote images' option in Reading preferences, it was driving me nuts!!

Hope that helps.
