Applications list and vmware workstation

Maybe you used 'sudo' while editing the .desktop file?
1) Check that the VMWare Workstaion .desktop launcher file it IS still at /usr/share/applications
2) If the file IS there, check permissions of it ('ls -laigh name_of_.desktop').

Make sure you have read and execute permissions, you might need to 'sudo chmod +rx name_of_.desktop')


elementary OS does not use Yelp. Part of the design philosophy is "minimal documentation". In a nutshell, if it needs documentation it's not a good design.


You can fill in 0,-, that way you could download it for free (gratis).

You need to change the sourcelist. Open the terminal and type;

sudo nano '/etc/apt/sources.list.d/appcenter.list'

replace all the hera with bionic

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

Then

sudo apt update

You might as well check rest of your sourcelists;

sudo nano '/etc/apt/sources.list'


How to install programms on the multiple partitions?

You might want to use two ext4 partitions of your HDD, one for programs and mount it as/usr and the second one for user documents and settings and mount it as /home.


The AppEditor seems to provide the ability to change a category assignment of an app. You could use it to put all in the same category.


I will have to investigate further to find an automatic solution, but this problem occasionally happens to me as well.

The solution I use is to run

sudo restart NetworkManager

This restarts network manager cleanly and re-establishes any connections you had.

There was a bug in older Ubuntu systems where this would occur and you had to add a command to one of the files uses by pm-utils, but it seems this problem is not exactly the same as the previous one.


What is the shortcut key to rotate photos in Photos app

[ or ] but it only rotates the image right, so you need to press the key 3 times to rotate it to the left. Alt Gr 9 does the same thing. Ctrl [ or ] also rotates the image to the right. Ctrl Shift [ or ] doesn't work.


Cannot detect secondary monitor via HDMI, Intel GPU

Have you recently installed updates?

It's always possible there was an issue / conflict in a new package. Installing new updates could help. You could try booting up to live USB and see if the HDMI works in that setup? Then at least you'll know it's not physically broken hardware or cable.

You can use AppCentre or on the command line type:

sudo apt-get update
sudo apt-get full-upgrade

See if this helps, otherwise checking with live USB is option.

If you have added any additional PPAs they could also have produced a package conflict. Hope this helps.


Dual boot redirecting to windows 10 instead or OS choice

Well, the simpliest way is using Boot-Repair utility.

You can find the instructions on official website.
There are several options such as preparing bootable stick with special image, or installing it on live session and using from there.

P.S.: be careful with advanced options.


Mail application resets watch for new mail

It sounds like you've encountered a bug in Pantheon Mail. I've experienced a somewhat related issue: when I turn off "always watch for new mail" and close the application, I still get mail notifications.

You can report a bug by following these instructions.


You can use killall <process> in the terminal to completly stop the background processes of the applications.


How to install nvidia graphics driver for nvidia 820m on loki?

First, check what drivers are avaliable for your system:

sudo ubuntu-drivers devices | grep -o nvidia-[[:digit:]]*

Then install the one you want (replace XXX with the correct number):

sudo apt install nvidia-XXX

In case you have Optimus Technology you would also want to install this:

sudo apt install nvidia-prime

In case you want to fine tune your settings, is recommended to install nvidia-settings as well:

sudo apt install nvidia-settings


You ll have to do a clean install. I would recommend it regardless to be honest. Good luck! Juno seems quite fresh in colours and slim in responsiveness!


Open your terminal, and add a new PPA to your repositories, then install it.

sudo add-apt-repository ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install conky-manager

To run conky at startup, you go to Applications -> System Settings -> Applications -> Startup -> Click the + icon at the bottom left corner, enter conky in the the bottom text input and hit enter.

I use conky with elementary OS 0.3 Freya with no issues.


Grub2 unknown filesystem after apt dist-upgrade

Based on you comment I have a possible solution:

I saw a comment on another forum of another distro (Archilinux) that having the external drive connected caused this. Disconnect it and try again by running the command

sudo update-grub

A side question (use comments to answer), what format has hat external drive?


How do I set a custom screen resolution as permanent?

You can run the command each time you log in by adding it to ~/.profile. See this answer for more info.

I'm assuming here that this resolution doesn't appear in Display settings because it isn't a native resolution of your monitor. (If it does appear in display settings, using that would be the easiest way to make the change.)


Lots of updates but don't know if they are working

If you go to the terminal prior to updating you can use

sudo apt list --upgradable

it will show you the list of packages that are available for update.


Did you enable the wingpanel notifications? By default elementaryos doesn't allow notifications to third party apps.

In order to enable it for third party apps I recommend you to use these steps.

This community is the wrong place for reporting issues, sorry. If you want to report an issue with the developers, you can do that as described in How can I report an issue with elementary OS to the developers?

Unfortunately, elementary OS Luna is not actively developed anymore. While the operating system is still secure (as the Ubuntu base still delivers security updates), there are very few elementary OS developers still working on delivering bug fixes and updates for elementary OS software on Luna. Therefore, reporting this issue will most likely not result in any fix.


How can I "disable/enable" my laptop's touchpad on Elementary OS Loki?

Do xinput list to see the name of the touchpad. Let's say it's "SynPS/2 Synaptics TouchPad".

(the number after id= can be used instead of the name of the device, but id may vary between systems and can even be changed after reboot in some cases. Using the name is safer, as the wrong id can disable the keyboard, etc)
The command to disable would then be
xinput set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 0

Enable:
xinput set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 1

Change accordingly to YOUR device name.
These two commands can then be associated with shortcuts under Keyboard > Custom > Add

These two commands can also be run through the Applications launcher:
Having Gedit as text editor:
sudo gedit ~/.local/share/applications/disable_touchpad.desktop

With the lines:
[Desktop Entry]
Name=Disable touchpad
Comment=Set your touchpad preferences
Exec= xinput set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 0
Icon=touchpad-disabled
Terminal=false
Type=Application
StartupNotify=true
Categories=GNOME;GTK;Settings;HardwareSettings;X-GNOME-Settings-Panel;System;

Also:
sudo gedit ~/.local/share/applications/enable_touchpad.desktop

With the lines:
[Desktop Entry]
Name=Enable touchpad
Comment=Set your mouse and touchpad preferences
Exec= xinput set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 1
Icon=input-touchpad-symbolic
Terminal=false
Type=Application
StartupNotify=true
Categories=GNOME;GTK;Settings;HardwareSettings;X-GNOME-Settings-Panel;System;

Now, just use the Super-Space launcher and type the first letters of 'touchpad', 'enable' or 'disable'.

Once created, those launchers can be accessed in different ways, like added to the dock etc.


I had to upgrade libinput to fix some touchpad issues on my laptop, I detailed the process in another answer: https://elementaryos.stackexchange.com/a/10213/8179


Currently running Ubuntu and Windows dual boot - will installation overwrite both partitions?

You can choose how you install elementary OS. In the installer, you will probably have these choices :

Erase Ubuntu and reinstall : Install elementary in the ubuntu partition
Erase disk and install : Take the full disk only for elementary
Something else.

Something else will bring you in a partitionning tool. You have to reduce one of your existing partitions and create a new one if you want to install elementary OS + Ubuntu + Windows (I personally don't recommend this, if you do, be careful with grub.)


Loki 0.4.1 - How to change home folders names on the left pane?

Try deleting the offending bookmarks and then recreate them.

To delete:  Choose "Remove" from bookmark context menu, or just drag them out of the window.

To recreate:  Show the home folder and then choose "Bookmark" from the folder context menu, or drag the folder onto the sidebar.

When first created they will appear at the bottom of the list (above Trash) - just drag into the desired position.

This assumes you have not changed the default user special directories (ie they are still in your home folder).   If you have changed them, just navigate to the appropriate places to recreate the bookmarks.

You could also try renaming them using the bookmark context menu.


Skype won't launch on Elementary OS Loki

Will Elementary OS 32 bits performs better then 64 bits on Intel Atom N455 processor?

While it probably won't result in a noticeable difference, a 32 bit install will use slightly less RAM overall as the OS addresses it differently and you don't need to load both 32 and 64 bit libraries into memory if programs require them. Use the free -m command to see if you are running out of RAM when these stutters occur.

If you have a little to spare you could look in your BIOS to see if you can allocate more or less RAM to the integrated graphics card.

Where possible, it's recommended to not use PPAs at all. Adding a PPA is essentially giving the owner of the PPA root (administrator) level access to your system. It is possible for them to maliciously or accidentially replace system packages with broken/unpatched/malicious versions.
PPAs by trusted vendors are probably fine (Ubuntu, Libreoffice, etc), however, always be aware they run the risk of breaking your system if they are misconfigured.
If the software you want is available from flathub.org, then I would recommend getting it from there instead as Flatpak is a much more safe and secure packaging format.


How can I completely unbind the default "switch windows" keyboard shortcuts?

I discovered a workaround via this answer to a related question.

First, use gsettings to find the internal configuration setting we wish to change:

gsettings list-recursively | grep -i switch
# ...
# org.gnome.desktop.wm.keybindings switch-applications ['<Super>Tab', '<Alt>Tab']
# ...

Then, change the individual setting as necessary. In this case:

gsettings set org.gnome.desktop.wm.keybindings switch-applications "['<Super>Tab']"

As suggested by Daniel in the comments above, I have reported this as a bug.

'packages.elementary.io/appcenter xenial Release' does not have a Release file

Error 521 on the Host (https://packages.elementary.io)! Just wait, the error will be fixed soon


That is a System Tray, and the answer you link to is somewhat contradictory.

  elementary OS does not have a system tray
  ...
  Currently (in 0.3 Freya), only the Ayatana Indicator API is respected.

Ayatana Indicators do exist in a system tray in Freya, however they will not in Loki.


How good of a support does elementary OS offer for development?

If you try:

apt-cache policy nodejs

You will know that nodejs is the same one used in Ubuntu and it is downloaded from Ubuntu official site.

For bugs, you can report them to bugs.launchpad.net.
If you have questions, they are off-topic in Ask Ubuntu, it does not support derived distributions.

You better ask here in Elementary OS (Stack Exchange) or answers.launchpad.net.

You should ask in Stack Overflow if it is a generic programming question.


It turned out that it wasn't the fault of Evolution. I had to trust my friend's GPG keys (CC461E31) for encryption to work. This would be a solution. Another will be, and I quote from mailing list,

Configure evolution not to check that and instead assume that if you
have a OpenPGP key in your keyring for a given email, it should encrypt
the messages for that recipient using that key:
Edit → Preferences → (Choose your account) → Edit → Security → Check
Always trust keys in my keyring when encrypting

Nothing but wallpaper shows up after login

I know it's pretty late already but I had the same problem and I solved it by uninstalling and reinstalling pantheon. You can access terminal at login screen by pressing ctl+alt+f1. Then login.

Uninstall pantheon:

  sudo apt-get remove pantheon

Reinstallation:

  sudo apt-get install pantheon

and the reboot

  sudo reboot


this is what worked for me.  Now, I can set the screen brightness with my function keys, or the gui, and when I plug in the AC adapter the brightness remains constant.  The computer also starts up with whatever brightness level I had set it to, prior to shutting it down.

In the terminal, run (replace gedit with whatever you're using for your text editor):

gksudo gedit /etc/default/grub

Look for the line that looks like this (there may be other things within the quotation marks, but what you are looking for, specifically, is the 'acpi_osi='):

GRUB_CMDLINE_LINUX="acpi_osi= (there may or may not be other things written here, but don't worry about them)"

After the "=" simply type: linux

So, now the line should look something like this:

GRUB_CMDLINE_LINUX="acpi_osi=linux (again, there may be other stuff here)"

Save the file

In the terminal run:

sudo update-grub

restart your computer and your problem should be solved.

How do I make all window corners to be rounded?

In what looks like a forward-looking change according to issue #5 on the stylesheet's GitHub repo, apps have to request the rounded corners via a class in elementary's GTK+ stylesheet. See pull request #20 for the relevant code. I'm not sure the apps have caught up with this change, though.

There's probably a way for you to modify the stylesheet so that the apps you desire have rounded corners (check out /usr/share/themes/elementary/gtk-3.0/app.css), but you'd need to know the class for each app's window frame, to which you'd add a border-radius value -- it looks like it isn't really standardized at the moment.


This was (and is) a Gnome application that you can run with the gnome-power-statistics command (if neeeded, it is in the gnome-power-manager package).


Stuck at ip_tables (C) 2000-2002 Netfilter Core team when install

I resolved this problem with deleting efi folder, try this if nomodeset is not working


Solution by Demelza:

Open a terminal and type the command: rfkill list

It will list all your network hardware available, and you should notice one that's called "acer-wireless". Looks like Linux kernel loads an Acer module, which conflicts with our Wi-Fi chip.
You can deactivate it for the current session with the command:
sudo modprobe -r acer-wmi

Your Wi-Fi should now be working as intended.
If you want to make it permanent, just edit your /etc/modprobe.d/blacklist.conf file and add the following line at the bottom of the file:
blacklist acer_wmi

It'll blacklist the conflicting module and you'll have fully working Wi-Fi.


Securely Wipe/Shred Files in Pantheon via Right Click menu

This should be possible with a contractor, something like this:

[Contractor Entry]
Name=Shred
Description=Securely delete a file
Icon=
MimeType=!inode/blockdevice;inode/chardevice;inode/fifo;inode/socket;
Exec=shred -f -z -u %f

Place this in /usr/share/contractor/shred.contract and you should then get an entry when you right-click on a file.


First read this article just to learn the basis. https://www.redhat.com/sysadmin/sysadmins-dont-sudo
Then the best idea is to type sudo visudo and add yourself to the root group or wheel (Red Hat, CentOS, Fedora).
You must read about the visudo command and how to make a user as an additional root admin in the system.
I do not want to write an elaborate.
Just for your information that it is not secure. Probably, I did not check it, there is a need to edit a .profile file or .bashrc file to make it work. But I need to check it.
Anyway it this is really bad idea, because you may just screw your system. Root is God and God can create and destroy.
There is no need to run as root every day with elevated permissions. This way you will run every app as root and simple java script during browsing the Internet with any browser will be able to harm your system because of elevated level.
We use su or sudo. I usually use:
sudo su -

or
sudo -i

To work as root in terminal.
But this is for experienced users. I do not recommended to work as root for inexperienced user.

Elementary OS (as most other Linux distros nowadays) comes with a Live Image. That means you can "burn" the ISO image to an USB Stick (hint: use the programm "Etcher" for that), plug that stick into your laptop and boot off from said USB stick.

No modifications are made to your existing OS. You can try out nearly all the features like WiFi support, keyboard hotkeys, sound, ...

Once you are certain that everything that is supposed to work actually does work you can fire up the installer and make the OS your permanent choice. During the installation you can even select between wiping the entire harddrive (and thus effectivly removing Windows) OR you can resize the existing partition and install Elementary OS alongside Windows.


Tried to install E OS on my dell xps 9550 and found the solution for your problem while searching for mine (how ironic)

2 Boot windows

3 Run command 'msconfig '

4 Tab 'boot' and tap 'safe mode'

5 Restart, enter BIOS and switch RAID to AHCI

6 Restart and windows will boot in Safe mode.

7 Run msconfig and untap safe mode.

8 Restart,  insert USB and boot ubuntu.

9 This time it will locatie your SSD drive.

Pls note that this will not work for a HDD


how to define a grid and snap windows to it?

This is generally a feature associated with a tiling WM. Gala is a floating WM and does not support anything more advanced than window snapping.

An alternative would be to 'fake' tiling features using something like Stiler, which lets you bind keys to resize / move windows, emulating the behaviour of a tiling WM.

Save and try starting eclipse. : - )

How to fix elementaryOS touchpad problem

Thanks for providing the necessary information, after a lot of googling and reading bug reports, it seems the main solutions are as follows, I'll start with the easiest although I know you have already tried it.

Adjust the touchpad settings using synclient. synclient -l will give a list of options, for your problem in particular I would start with pressure settings, in particular synclient PressureMotionMinZ=25. Changing synclient settings is not permanent so when you work out which ones to change you will need to add some start up commands but on the other hand if you mess it all up you can just reboot to start again.
Update your kernel. The bug reports reported bugs in kernels 3.3 right through to 4.2 with various issues with the alps touchpad, although I couldn't find anything specific to your problem. Kernel v4.4 is available however in the standard repos so you could try:

sudo apt-get install linux-image-generic-lts-xenial

Build your own Kernel Module (driver). I wouldn't try this unless your comfortable with building from source code but you can find instructions by googling 'dkms alps touchpad'. Don't forget to update your initramfs after you build your own module.

sudo update-initramfs -u

Sorry I couldn't be more help but with these types of bugs and without the ability to sit on the computer and run various tests it's hard to diagnose it down to one specific problem.


How to install Sublime Text 3 on elementary OS?

There isn’t an official PPA, but you can use webupd8's PPA.

Just try this on your terminal:

sudo add-apt-repository ppa:webupd8team/sublime-text-3
sudo apt-get update
sudo apt-get install sublime-text-installer

Also you can download the .deb file from http://www.sublimetext.com/3 and install it.


How do I scan for and remove duplicate files in Pictures and Music folders?

The best tool I've found so far is DupeGuru. It's free and there is a PPA for Ubuntu. There are also specialized versions for picture and music files.

sudo apt-get-update; sudo apt-get install dupeguru-se dupeguru-me dupeguru-pe


"unable to install grub in /dev/sda. This is a fatal error."

This always works for me :-
1. download & create liveimage of supergrub iso.
2. boot super grub.
3. locate bootable OS  on the pc. ( if more than one OS on the PC)
4. boot you preferred OS.
5. Login & go terminal as root.
6. usually most people prefer grub on "/dev/sda" but that's no always the case.
So select the drive you prefer to install grub on.
7. run "grub-install /dev/sd?" change the "?" to the letter of the drive you wish to install grub on.
8. then run "update-grub" that should do it.

you could also run "grub-mkconfig -o /boot/grub/grub.cfg".

Note:
A. I always suggest installing "grub-customizer", this is a great graphical app to manage your grub. ie. update,add, change the OS boot order   , backup & save grub. Even move to a different drive.

B. Supergrub
 disk or "RESCATUX" are incredible tools to carry around with you.

Support for ibus on elementary is not yet complete, but you can still use it with some inconsistencies I just tested it and the only problem was the indicator on wingpanel that didn't update accordingly when switching between different input methods (not a problem if you are only going to use the Vietnamese layout).

You should have ibus-unikey installed, if you don't do it with this command:

sudo apt-get install ibus-unikey

Now configure ibus through ibus-setup. To do this, run the command on a terminal and go to the input method tab.

Check the box beside "Customize active input methods"

Then click the menu below, scroll all the way to the bottom, and select Vietnamese > Unikey.

Finally click on the add button and make sure you left Unikey as the active input method, then close the window.

Now you should be able to type using Unikey. To switch layouts use Ctrl + Space , ( instead of the default  Alt + Space  ), if you want to change this shortcut then this has to be done from ibus-setup on the General tab and not from the shortcuts GUI on Switchboard.

Failed to fetch updates, Too few items to process when trying to update from AppCenter

You have two problems here.

The first is that something has happened to your http://archive.canonical.com/ubuntu repository as it has loki as the release codename when this should be xenial.

You will need to replace all instances of loki with xenial in /etc/apt/sources.list and the files within /etc/apt/sources.list.d. See another of my answers here for more information: https://elementaryos.stackexchange.com/a/15236/9699

The second issue is you have some PPAs enabled that aren't compatible with loki or that don't exist anymore:

versable/elementary-update is not loki compatible
moka/stable doesn't exist anymore.

So removing both of those PPAs from your sources files should also help resolve this issue.


Firefox 49.0 doesn't show words in italics on Wikipedia

I'm unable to reproduce the error. I suggest right-clicking on the area you want to inspect and selecting "Inspect Element". Look if anything is out of the ordinary or try to toggle the CSS if you don't have the italics element showing like I do above. Page might just need a refresh.

Worst comes to worst, reinstall Firefox. It's likely something off with your configuration. If the issue recurs, it's a bug to take to Firefox's bug tracker.


First of all, the new wingpanel and it's indicators are work in progress and are not ready for productive use.

The keyboard indicator is listening on the org.gnome.desktop.input-sources gsettings entry. Maybe you don't have it. It also depends right now on the switchboard keyboard plug for the layouts file.

Btw. you also have installed wingpanel-indicator-ayatana which only works on ubuntu. Also you are missing some dbus interfaces which the indicators depends on (probably you have the wrong versions since you are on debian).

Alucryd managed to make it work on arch. Maybe you can look up something there.

How to get my elementary laptop to show my quad-core CPU info?

Sorry to tell you but 3217u is a dual core processor. You can see its specifications at:
Intel i3 3217u

However you can add some variables to your .conkyrc to see information about your cores. For example, you can add:

${cpu cpuX}

With x=0 to see total CPU usage in percent, and X>=1 to see individual cores.

For more information about conky variables, you can see:

Conky variables

To start conky on boot you can add it  in Configuration > Applications > Startup .


I might be wrong, but I am almost sure that before I installed Juno I read somewhere that it was recommended to remove older versions of elementary before installing. I had no previous versions, so I didn't put all too much attention to it and went on with the parts pertinent to my installation.
So the question would be: did you remove Loki beofre attempting to install Juno? Once you got Juno, Hera will come automatically, but apparently it's not the case with Loki-to-Juno upgrade.


I found the answer: http://ubuntuhandbook.org/index.php/2016/10/pepper-flash-chromium-opera-ubuntu/
I am sorry that i posted the question.


What are the 404 errors when I run update in terminal and how do I get rid of them?

There aren't packages in Versable PPA for trusty release, in which is based elementary OS Freya.

The last packages of elementary-update in this repository were builded to Luna, based in Precise release.

How can I install Intel HD Graphics proprietary drivers on elementary OS?

There are a couple of ways to achieve it:

Via Oibaf ppa, which is widely used among Ubuntu based distribution users. I use it myself, and everything works fine, except for a minor bug where for some reason libgbm1 is always stopped when updating the system.
Based on this WebUp8 article, you can manually add repository for Ubuntu 14.04

echo "deb https://download.01.org/gfx/ubuntu/14.04/main saucy main #Intel Graphics drivers" | sudo tee /etc/apt/sources.list.d/intellinuxgraphics.list

wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg -O - | sudo apt-key add -

wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg-2 -O - | sudo apt-key add -

Third way is in Saeed's answer.


How can I edit the "New" sub menu when I right click in Files?

This menu is populated from the "Templates" folder in your Home. You can add files and folders here to create submenus and items. If you'd like to remove those items, you must remove them from the "Templates" folder.


Can I enable the desktop to create files, folders and shortcuts? In loki

How can I disable natural copy & paste in Terminal?

The ability to paste clipboard contents into the terminal using the standard Ctrl + V shortcut is called "natural-copy-paste" and you can disable it in the dconf settings.

If you haven't already done so, install dconf editor using this command:

sudo apt-get install dconf-tools

Open dconf editor and navigate to org > pantheon > terminal > settings.
Once you're there, you can untick the option.

Now pasting into the terminal using Ctrl + V no longer works, and the former default shortcut (Ctrl + Shift + V) is restored.


Discord and TeamSpeak 3 clients randomly closing

Did you get them from flatpak? I've experienced problems with Discord when getting it from flatpak before. I usually just get the .deb file from Discord site. I've yet to had a problem doing it like that. Not sure about teamspeak though, sorry.


You can (re)install cups with

sudo apt install cups


Lots of microphone interferance on Freya

If you're still searching for a solution,

I had the same problem of noise from my cheap microphone with Loki. I found the module "module-echo-cancel" which should do the job.

To test it, enter "pacmd load-module module-echo-cancel" in your terminal ; then you should have a new input device with "echo cancelled" in the name.

If you're satisfied, you have to add "load-module module-echo-cancel" to your pulseaudio config file (for me, it's /etc/pulse/default.pa)


You did correct steps, now all you need is to Turn Off UEFI option in BIOS settings. You have enabled Legacy but didn't disabled UEFI. That is the only reason.

Finally, make sure when you boot from bootable USB, select Legacy Boot option.

Good Luck


How to read and write HD formatted with NTFS elementary OS?

Try using the device path:

parted -l

It will show some like this:

Look for the partition you want to mount, 9 in this case.

Try mounting:

sudo mount -t ntfs-3g -o defaults,rw,uid=1000,users /dev/sda9 /media /mount-point

If it works, replace UUID in /etc/fstab (at partition config) with device path like /dev/sdXY.

PostData: Mount point must have been created

sudo mkdir /media/some-dir-name


You could install Caffeine from ppa:caffeine-developers/ppa.

It runs as an indicator and can be used to prevent suspension.

You can also try this method, taken from Ask Ubuntu:

  For me it is important to just disable the "automatic Suspend" Because
  I still want to be able to do the "manual Suspend" in
  /etc/polkit-1/localauthority/50-local.d/com.ubuntu.disable-suspend.pkla

  So, I used:

[Disable suspend (upower)]
Identity=unix-user:*
Action=org.freedesktop.upower.suspend
ResultActive=no
ResultInactive=no
ResultAny=no

[Disable suspend (logind)]
Identity=unix-user:*
Action=org.freedesktop.login1.suspend
ResultActive=yes
ResultInactive=no
ResultAny=yes

[Disable suspend when others are logged in (logind)]
Identity=unix-user:*
Action=org.freedesktop.login1.suspend-multiple-sessions
ResultActive=yes
ResultInactive=no
ResultAny=yes

  Now I can click "Suspend" in the logoff menu. But the PC keeps running
  unless I send it to "Suspend".


Icons in Files are huge now and I can't figure out how to make them default size again

One possible solution:
Hold down the Ctrl key and using your mouse wheel.


"Erase disk and install elementary" partition defaults

This is what "Erase disk and install elementary" have done in my virtual machine:

One large primary ext4 fromated partition for / (boot and home altogether).
One more extended partition with swap partition inside.

It will be the same on real hardware but with larger partitions size.


You can fix the issue with the command line (in a terminal window):

sudo nmcli radio wifi on


Are you in Files? If so, that sounds like you need to open Files by right-clicking on it and selecting "Run as Administrator," or something to that effect (I'm not on my elementary machine right now.).
Then try opening the file.
On a side note: if it's a theme, and it's in the proper folder, can you just change the theme by ctrl+right-clicking on plank and changing the theme in the dropdown?


You can try this:

First open Terminal and type the following command:

sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8

Second logout and login again or reboot your machine.


Displays failing to set a resolution on a triple monitor setup

Not sure it will going to work, but if I am in your place I will do a backup of ~/.config/monitors.xml, open it in some editor (elementary Code for example), change the resolutions there and restart the computer. If this leads you to a problem, you can delete the file into recovery mode or tty and restore it from the backup.

To create a copy of the file:

cp ~/.config/monitors.xml ~/.config/monitors.xml.bak

To restore the file from tty:

pres Ctrl+alt+F2, login with your username and password and execute:

rm ~/.config/monitors.xml && mv ~/.config/monitors.xml.bak ~/.config/monitors.xml

To restore the file using Recovery mode:

Select advanced options for elementary OS from the grub boot screen, then the first option with (recovery mode) into the name. Wait until the menu appears, choose Root shell. There you have to navigate to your user folder and restore the file, replace YOUR_USER_NAME below with your username folder.

cd /home/YOUR_USER_NAME/.config && rm monitors.xml && mv monitors.xml.bak monitors.xml


How do I reduce the gap between the icons on the system tray?

Padding doesn't work anymore, for some reason, on Wingpanel 2.2.6.
There is however a solution and you can find it here:

https://github.com/mdh34/elementary-indicators/issues/1#issuecomment-546731215

Big thanks to Marcus André (https://github.com/marcussacana) who made this fix.


Please beware of building new kernels as if you don't get all the correct options for your hardware, your computer could stop booting. Though it should be possible to recover. The latest version of elementary now ships with kernal 4.10, so see if that meets your needs before building another.

However, if you still want to continue:

The apt-get source command will be failing because the Ubuntu source repositories are disabled in elementary OS. This reduces the network traffic needed when performing updates and does not affect 99% of users.

If you wish to re-enable those repositories, open /etc/apt/sources.list and remove the # symbol from the deb-src lines. You should only need to remove it from the two lines near the top of the file that end with xenial main restricted and xenial-updates main restricted.

Once you have done this, run sudo apt update and then the apt-get source commands should work as expected.


Yes, elementary OS Loki has been released. For the latest version of elementary OS, you can always visit elementary.io.


Try nmcli radio wifi on through terminal

Unable to push latest software update in Loki

Tried via terminal?

sudo apt-get update && upgrade


I fix this replacing juno for bionic on

/etc/apt/sources.list.d/appcenter.list
/etc/apt/sources.list.d/patches.list
/etc/apt/sources.list.d/elementary.list

to find this list of files you can use

sudo grep -R juno /etc/apt


You should be able to just click "Install alongside Windows", without the need for boot repair or any other modification. It's what I did on my most recent installation.


How can I disable transparency throughout the UI?

In order to turn off transparency, open a terminal session and run the following commands, depending on your version of elementary OS:

0.4 Loki

Turn off transparency in WingPanel

gsettings set org.pantheon.desktop.wingpanel use-transparency false

Turn off transparency in Terminal

gsettings set org.pantheon.terminal.settings background "rgba(37, 46, 50, 1.0)"

0.3 Freya

Turn off transparency in WingPanel

gsettings set org.pantheon.desktop.wingpanel auto-adjust-alpha false
gsettings set org.pantheon.desktop.wingpanel background-alpha 1.0

For this change to have an effect, WingPanel needs to be reloaded (log off & log on again).

Turn off transparency in Terminal

gsettings set org.pantheon.terminal.settings opacity 100

Reset to default

Use the gsettings reset command to restore the default value of a setting, for example to turn back on WingPanel transparency in 0.4 Loki:

gsettings reset org.pantheon.desktop.wingpanel use-transparency


There are someways to solve that:

If you're running on 32 bit version of eclipse try to install 64 bit version.
Also It appears on old versions of eclipse try to install latest version. But if you are using older version than Kepler try to adding these two lines in your eclipse.ini :

-Dorg.eclipse.swt.browser.DefaultType=mozilla`
-Dorg.eclipse.swt.browser.XULRunnerPath=/dev/null`

(I didn't try them in Kepler or Luna maybe it works for them)

If you are using OpenJDK try to install Oracle JDK.
Try to increase memory sizes (this way solve my problem before), So adding these lines to eclipse.ini :

-XX:PermSize=256m
-XX:MaxPermSize=512m
-Xms1024m
-Xmx2048m

Also you can read this article for more info.


How should I design a "Create Project" wizard?

Check out The Wizard Anti-Pattern by Stef Walter. It's part of the "See Also" in the Design Philosophy section of the HIG.

The TL;DR is to avoid wizards at all cost. Get as much info automatically as you can, make solid opinionated design/engineering decisions for most other things, and only ask for things that are really essential to ask about.


How to make Maya show events in Wingpanel

You can enable a option to show events in the date time indicator with the following command:

gsettings set com.canonical.indicator.datetime show-events true

Alternatively, you can enable using dconf-editor

sudo apt-get install dconf-editor

Now open dconf-editor --> com --> canonical --> indicator --> datetime --> show-events


How can I remove the password prompt from the lock screen?

Upgraded Nvidia and now have blank screen

This is a common error when the system doesn't know what driver to use.
To install nvidia propretary drivers is quite simple:
-You need a piece of software called Software & Updates;
Apart from being able to control all the PPA installed and repositories, under the additional drivers section you can swap in-between proprietary drivers for nvidia and the open source Nouveau drivers counterpart.

To install Software & Updates:

sudo apt install software-properties-gtk software-properties-common

I always suggest to create the configuration file at the end of the driver installation:

sudo nvidia-xconfig


How can I turn off hardware acceleration in epiphany?

Hardware acceleration can be disabled by setting an environment variable. Run it from the terminal like this:
$ WEBKIT_DISABLE_COMPOSITING_MODE=1 epiphany
See https://trac.webkit.org/wiki/EnvironmentVariables for other environment variables that you'll probably never want to use.
If this environment variable fixes your problem, then there's a good chance it's a bug in your hardware or graphics driver, but there's an equally-good chance it's a bug in WebKit. Regardless, your best hope of getting help is to report the issue on https://bugs.webkit.org.


Are all GTK 2.0 or GTK 3.0 themes compatible with all desktop environments?

No. There are some themes that are specifically for ubuntu's desktop unity for example, and that works on elementary but it doesn't look good, some features aren't shown, some parts look broken. You should look for Elementary themes.. Also you should pay attention if the themes are designed for Freya or Luna because they are not compatible.


No brightness controls after fresh install

Please click on the battery icon from wingpanel(top bar) you will be able to increase or decrease the screen brightness from there.

Also if you go to system settings and then power, you can see another bar to increase or decrease the screen brightness.

Hope this helps. Please do let me know what you find.


For anyone else who ever has this problem, the solution I stumbled upon was to use:

akonadictl fsck


You might want to look at the package redshift (universe packages) or fluxgui (in the PPA: https://launchpad.net/~nathan-renniewaldock/+archive/ubuntu/flux)


Is it possible to display keyboard shortcuts like in Unity?

I did have a update for wpasupplicant:

wpasupplicant/xenial-security 2.4-0ubuntu6.2 amd64 [upgradable from: 2.4-0ubuntu6]

But wpa_supplicant -v still simply says v2.4.


SOLVED: This issue was due to having the SATA mode set to RAID in BIOS. It was resolved by first following this post, then switching SATA mode to AHCI in BIOS and booting to Safe Mode in Windows which seems to install the AHCI driver needed to start Windows in AHCI mode.

After this, I was able to again restart from the elementary USB, choose "Try without installing" and starting the installer from the desktop. When arriving at the "Installation type" screen I was able to see the SSD, hooray! :)

However, after finishing the installer and rebooting it booted straight into Windows, bypassing GRUB - but that's a topic for another thread.


Bluetooth headphones not showing up as sound output on Dell XPS 15

Thanks Jeremy31, I tried the a2dp.py script but I was getting the following error:
`Cannot find

bluez_card.04_52_C7_1B_7B_BC` using `pactl list cards short`. Retrying 8 more times

After trying a few other suggestions I tried https://askubuntu.com/a/836202/519324.
I used the regular Elementary bluetooth discover flow, then I installed Blueman but the Audio Profile didn't have a submenu. Running Setup on my device, selecting Connect to: Handsfree suddenly my device appeared as sound output. So now it sort of works. I still need to restart my bluetooth device frequently to get it to work properly.
When I'm home I'll try this with my other bluetooth device, see if that fixes it for that one too.

Update: In regards to my Bose QuietControl 30, I've had to re-pair a couple of times in the mean time and usually I've had to retry the setup part a couple of times before it would suddenly start working again.
I don't need to restart my bluetooth device that often anymore. I still need to restart it when it was on before my computers boots, then I need to restart for it to reconnect. And if I walk to far and the audio get's off-sync.
I've never been able to get my UE Boom 2 to work.

I've also tried replacing the Atheros Qualcomm Killer with the Intel 8265, which also forced me to upgrade the kernel, but that gave me even more issues. The bluetooth connection would always stop after a few minutes, even after removing tlp.


The share plugin in switchboard seems not to work in Loki

I noticed that running xmodmap works until the system is restarted. In my case it helped to add it to System Settings > Applications > Startup. The paths in the command should be absolute, otherwise they will not be recognized correctly:

/usr/bin/xmodmap /home/{your_user_name}/.Xmodmap

I realize that your problem is different, but this solution might help. You might also consider adding this command to .profile in your home directory (although it didn't work in my case).


I simply ran these commands and it works pretty well!  Nothing else was needed.

Go root first by executing sudo -i or sudo su in the terminal and then execute the commands bellow,

echo -e "\n# applespi\napplespi\nspi_pxa2xx_platform\nspi_pxa2xx_pci" >> /etc/initramfs-tools/modules

And you haven't changed anything? Because I really don't get what's happened here.

The issue is that it's pointing to "hera" in the repository, which doesn't exist. It has to be "bionic". I know there's a way to reset apt, but I'm not sure how it'll handle the PPAs of elementary, meaning, you'll have to edit them yourself.

You'll have to edit /etc/apt/sources.list and every file in /etc/apt/sources.list.d/ and change every occurrence of "hera" to "bionic"

Here's a little guide to using sed. https://www.cyberciti.biz/faq/how-to-use-sed-to-find-and-replace-text-in-files-in-linux-unix-shell/
It might be a good idea to make copies of the files you're editing beforehand, just in case. :)


Once you had installed gpointing-device-settings, did you actually use it? I'm not sure how you'd go about translating them, but the instructions in this post are quite likely to fix the problem you're encountering. It strikes me that the problem you face is that your drivers are not right for your hardware. Take a look, see what you can work out. If you don't make any progress let me know what you've tried in a comment and I'll install on my old Lenovo laptop to see if I can reproduce it.


Is it possible to remove Steam from Plank while running?

Yes, it is possible.

You'll need to set the $STEAM_FRAME_FORCE_CLOSE environment variable before run Steam. There's a couple ways to do that. The easiest I found is to add the following to the end of ~/.profile:

export STEAM_FRAME_FORCE_CLOSE=1

Then end your session and log in again. That should do the trick.


How can I adjust individual icons in the Moka icon theme?

You can try setting the Moka icon theme to inherit from the elmentary icon theme. Edit the index.theme file and add elementary to the Inherits property:

Edit the Inherits property:

Inherits=elementary

You might have to switch themes, before the changes take affect.

Many people have their touchpad that does not work anymore or badly after updating to elementary OS Hera 5.1

Question 1

Question 2

Hope this will solve your problem


I have a booteable usb with elementary OS,  and it's fast, light and with no issues.

I recommend installing it on a single partition / without swap. The swap partition requires so many hits per use, which eventually damaging the USB in a short period of time, and slows down the performance, since the usb access speed is less than a hard drive or ssd.


Laptop goes to sleep on any keyboard key press

Try to update plugging in  external keyboard and mouse. I have solved the problem in this way.

I'm connected to VPN right now.
Hope this helps.


Can I increase the amount of time before I'm asked to force quit an app?

No, this is not possible. The value is hard coded in LibMutter, the programming library behind the window manager in elementary OS.

Even while loading, an application should remain responsive to the window manager. The application becoming non-responsive will trigger this dialog. This is by design. The window manager is behaving properly. You should file a bug report against software that becomes non-responsive to prevent this behavior in the future.


nvidia driver: pantheon doesn't launch after apt upgrade

No idea what happened. Reinstalled the system, apt upgrade again, now it works.

UPDATE

I've just ran into the very same problem on the newly installed system. That happened after I installed some packages. Excluding one after another, I found that it's nvidia-381. I uninstalled it via tty1 and now it boots as it should. To clarify, these nvidia drivers worked well before those system updates.

UPDATE

I've just figured out how to preserve nvidia driver and boot. I think this could be a bug somewhere in that version of the driver, that X server doesn't start because that happened before. However, I'm inclined to think the bug is somewhere else. It used to work without any problems. But here's what you can do:

Log in to another tty: for example, ctrl+alt+F1
sudo prime-select intel
sudo service lightdm restart

Done.

I got this same error when I was not connected to the internet. Looks like it is a bug in the installer but it should install if you have a internet connection


Make sure your system is up-to-date first (there have been updates related to language settings recently):

sudo apt-get update && sudo apt-get upgrade

Then go to System Settings > Language & Region (example screenshot), click on English in the left sidebar and then "Set System Language". You will likely have to enter your password to proceed.


Missing icons in Applications and System Settings in Loki

I had the same problem. I fixed it by doing the command:

sudo apt-get install elementary-desktop

You should get the icons back, but if you were using something like nautilus file manager, then you will have 2 different "files" folders show up in your applications menu.


Third party apps doesn't show on slingshot

I hate when my apps doesn't show up in the launcher too

I think AppEditor can solve your problems, it's a great app for editing our launcher/slingshot entries. Link: AppEditor

I will try to show you a practical example, hope it can help.

Goal: Create an icon to launch the Python Interpreter. As you can see I have no Python Interpreter in my Programming Section.

Step 1. Launch AppEditor.

As we can see there's no Python in Programming here as well:

Step 2. Activate -> Show hidden entries

Wow! Look who's here. Python it self! I will activate the 3.5

Step 3. Activate -> Show in Launcher. Don't forget to Save

Now let's check if it works.

That's it! You can play and change the categories and even edit the myapp.desktop file directly. In most cases this will work, of course we'll find some exceptions.

Manual alternative

Somtimes the .desktop file exists already but there's something wrong in the configs, check if they already exist in your .desktop files directory with the command: ls ~/.local/share/applications Check if there's a myapp.desktop already.

if not, you can create it yourself following the next steps.

Create a .desktop file in ~/.local/share/applications/myapp.desktop (you can use AppEditor to create a new one and it will give the same result)

Manual Ex: touch ~/.local/share/applications/chrome-browser.desktop
this example command would create a chrome-browser.desktop or you can use any text editor and just save there.

The contents of the .desktop file:

[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=Python(v3.5) #Application name, Chrome for example
Comment=Python Interpreter #This will show up on mouse hover
Icon=/usr/share/pixmaps/python3.5.xpm #icon full path or the application name ex. chrome
Exec=/usr/bin/python3.5 #path to the program executable
Categories=Development;  #the category it will show up
Terminal=false
StartupNotify=true

Example2. My manually crated netbeans.desktop launcher, in ~/.local/share/applications/netbeans.desktop

[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=Netbeans
Icon=/home/felipe/Downloads/apps/netbeans/nb/netbeans.png
Exec=/home/felipe/Downloads/apps/netbeans/bin/netbeans
Comment=Netbeans IDE
Categories=Development;
Terminal=false
StartupNotify=true

The executable is located in my Downloads/apps/netsbeans/bin directory


Says laptop battery is 100% but its not completely

A lot of laptops(like mine) have a BIOS configuration which sends the information as charging done when the battery has charged >=98 %. In Windows there are specific chipset drivers which correct this disparity to indicate exact values(as of Windows 7 they have to be installed). However, in Linux, they are often shown to be charged. So that is not an issue. AFAIK, this small error has been corrected in newer versions of Ubuntu.

# Install
$ sudo dpkg -i chrome-remote-desktop_current_amd64.deb

# Install dependencies
$ sudo apt install -f

You can also install Google Chrome Desktop in Chrome Web Store

https://chrome.google.com/webstore/detail/chrome-remote-desktop/gbchcmhmhahfdphkhkmpfmihenigjmpp

After activate the service chrome-remote-desktop.service

$ systemctl status chrome-remote-desktop

elementary OS boots into the command line interface

I had the same problem after having installed bad drivers for my graphic card, so in my opinion it's a problem related to some not working open source driver that are being installed by elementary. You can try downloading the correct drivers from your graphic card's producer's website and install them manually from the command line interface, this should solve the problem.
In my case I had to reinstall the system, if you have nothing to lose, also try to install elementary again.


How to switch screens if I only have one

You can manage displays (change resolution, choose primary, rotate ...) from System Settings -> Displays. Connect all your available displays and then click on Detect Displays (although they should be detected automatically).
You should now have multiple rectangles, one for each active display. All that's left to do now is to set their preferences, pick a primary one (click on the small star in the top left corner), and disable the ones you do not need (untick Use This Display). The rectangles can also be moved around to reflect the real arrangement of your displays.
After setting up everything (in your case, set TV as primary), unplug all the other displays (if any connected) and reboot, just to make sure your settings are preserved.


No, it's not installed by default. You can check if it's installed by entering in the address bar of your browsers about:plugins or here https://helpx.adobe.com/flash-player.html


you upgraded the version geary with a PPA right?
If that is the case you just need install ppa-purge, is an utility that remove a ppa and revert the changes that the ppa made to the system

first, install ppa-purge with this command

sudo apt install ppa-purge
after, use ppa-purge to remove the ppa of geary 0.11 (I'm using the PPA that is shown in all the webs with the note of geary update for this example, please check if is the same that you used), this is the command.

sudo ppa-purge ppa:geary-team/releases

just wait until the process end and your geary  would be the default of elementary.

Loki AppCentre updates page blank, can't do 1 update

I had this issue also and tried everything, including removing/purging appcenter, reinstalling, updating, upgrading, etc. but no suggestions that I found worked.
Finally, I looked through as many logs as I could and tried:

sudo apt-get remove appcenter
sudo apt-get purge packagekit

... as I had seen some errors thrown up regarding packagekit which seemed related.
Rebooted. Then reinstalled packagekit and appcenter, and everything works again!
Edit:  Interestingly, and sadly, this fix only lasted until my next reboot.  Then the problem is back.  This leads me to believe that for whatever reason, the problem might be related to appcenter's relationship with packagekit.
I have replicated the fix by removing packagekit again, and reinstalling, which so far is lasting.


Cannot turn off Caps Lock on lock screen

Try hitting CTRL + ALT + F1 to switch to TTY1 and then hit the caps lock key to see if it lets you change it then. If that works you can log back in by hitting CTRL + ALT + F7 on your keyboard.

If that doesn't work, there is something else you can try. I was having a lot of issues and kernel panic problems with some of the recent Linux 4.4.x kernels that were being pushed through updates. Updating to kernel 4.8.x fixed pretty much all of them. To update your kernel try the following:

sudo apt update
sudo apt upgrade -y
sudo apt install --install-recommends xserver-xorg-hwe-16.04 -y

Hope that helps. Good luck!

Is there a pantheon-integrated encryption utility?

Use Gnome Encfs Manager.  It's not an official elementary app, and it doesn't work from within Files, but it's worked really well for me.  You can have the program launch at startup, or you can just summon it from slingshot whenever you need it.  The interface displays a list of your encrypted stashes, so you don't have to hunt them down.  I like that I can have folders on my computer that are protected by a password so I don't have to worry if someone borrows my computer.
Be sure to use a strong password for the stashes, if you want to keep them secure.  Also, although Encfs is a really good and convenient way to quickly encrypt certain files or folders, be aware that it isn't without flaws.

Is it safe to upgrade to a new ubuntu base with the Software Updater?

Installing this "upgrade" will not update your system to Loki. It will set up elementary OS 0.3.x with the Ubuntu 16.04 base, which will probably not work properly. When Loki is released, you can upgrade by downloading the ISO from https://elementary.io/ and doing a fresh install.

From this answer about a similar 15.04 upgrade dialog:

  No, do not upgrade to the 15.04 base. Freya is built upon 14.04 LTS and only that. elementary OS' repositories do not even contain packages for 15.04 (or 15.10, for that matter). You will end up with a broken installation.

This dialog definitely is confusing, and hopefully future versions of elementary OS will get rid of it.


Those settings you refer to are not available in Elementary. I've tried changing icon size without success. But i use Elementary Tweaks to change text size and that works perfectly. It's enough for me. Try it and see if it helps.

No system tray icon for Ibus in Elementary OS Juno

Knumber10

From your screenshot it would appear that you have a few extra icons in your wingpanel so this solution may be redundant.  However, let's give it a shot!

There is a site maintained by mdh34 that is the unofficial guide to restore indicator functionality on Elementary OS.

The TLDR boils down to this, if you want to install the prepackaged .deb packages then you would follow these steps:
1. Download the patched Ubuntu indicator-application package here.
2. Download the latest wingpanel-indicator-ayatana package here.
3. To install the packages, you can use a .deb installer or enter the following command in Applications -> Terminal (or Win+T):
Type: cd ~/Downloads
Type: sudo dpkg -i indicator-application-patched.deb
Type: sudo dpkg -i wingpanel-indicator-ayatana_2.0.3+r27+pkg17~ubuntu0.4.1.1_amd64.deb
NOTE: The command above should be entered on one line only.
4. Once you've installed both packages, a reboot should get your indicators working in Pantheon.

What I like about mdh34's site is that he shows you the process of patching the files on your own.  That appeals to the security conscious side of my nature.  However, I understand that this is not for everyone.  If you are comfortable with the pre-patched files, go ahead and use them!

I hope that helps!  Good luck.


Odin beta screen freezes on boot but computer still working after installing NVIDIA drivers

I did it! I now have NVIDIA 460 drivers working perfectly on Odin beta 1.
What I did was:

Installed kernel headers with:
sudo apt install linux-headers-$(uname -r)

Installed nvidia drivers with:
sudo apt install nvidia-drivers-460

Recreated grub config (thanks for the tip u/Ashtefere)
sudo grub-mkconfig -o /boot/efi/EFI/ubuntu/grub/grub.cfg


Images are not displayed in background selection

Open terminal and run the command:

sudo apt-get install --reinstall elementary-wallpapers

You can reinstall from software center.

If not working, update to 0.3.2 would solve the issue.


Name of elementary OS terminal (to open new terminal window from within Terminal)

I know this is an old thread, but the approved answer is now incorrect and this is still the top Google link for this question, so in new versions of Elementary OS, the terminal is called io.elementary.terminal


Custom keyboard shortcuts dont work after reboot

Please consider asking your question on an Arch forum (like bbs.archlinux.org), because I'm not sure if these commands apply on Arch.
On eOS I can use gsettings to change the keybindings via terminal.

First get the current binding with your logged in user:
gsettings get org.gnome.settings-daemon.plugins.media-keys terminal
The output is something like:
'<Primary><Alt>t'

To change this, you can use:
gsettings set org.gnome.settings-daemon.plugins.media-keys terminal "YOUR-KEYS"
Use the same syntax as in the output earlier and put it in quotation marks. As far as I know, gsettings doesn't check if these keybindings are already in use, so to be sure just try them, before hitting the set command.
After that you can rerun the get command, to check if it worked or hit the keys you specified.

EDIT: I think, I misunderstood what you want..
In the case you want to change the default terminal-application, the commands would be:

Get the current value and the correct syntax:
gsettings get org.gnome.desktop.default-applications.terminal exec
Example output: 'pantheon-terminal'

Set gnome-terminal as default:
gsettings set org.gnome.desktop.default-applications.terminal exec "'gnome-terminal'"


Packaging system broken: Error with libqtcore4 package when installing krita (Freya)

To install the latest and correct Krita on Ubuntu and derivatives (elementary OS) run the following commands

sudo apt-get update
sudo apt-get install krita

This will add the PPA and install Krita.


Should i use Elementary OS for developing applications?

If you don't like other distros' UX/ergonomics then you won't like Elementary OS. If your issue is more aesthetic then you might like Elementary OS. The polish is largely surface level, but the core applications and feel are going to be reminiscent of other Debian based distros.
I, for one, can't stand development in Windows and don't choose to pay the Apple tax. I like Ubuntu, Mint, and Elementary for user-friendly distros.


Enable notifications for VLC:

Open menu Tools > Preferences.

Now, under Show settings, select the All radio button. Then, from the left sidebar, choose Control interfaces. There, check the LibNotify Notification Plugin checkbox, then click the Save button.

By default the notification appears for 4000 ms, i.e. 4 seconds. You can change this duration in the same preferences window, by selecting the Control interfaces > Notify option in the left sidebar.


How to change the date format across the entire system

I do not think it is possible to enforce one custom date-time format on every thing unfortunately.  If you search for "format" with dconf-editor you will find 8 or 9 different settings for different apps that control date and/or time format they use and most of those do not provide for an arbitrary custom format. For example for the wingpanel the time can be '12h', '24h' or 'ISO'.  In the 'Language and Region' plug in Switchboard you can use the "Format" selector to choose a set of pre-set formats suitable for different locales but no customization.  It is not part of elementary philosophy to cater for much customization, which may not please some users.


Wireless and Internet settings disappeared from system settings

Run this command line

sudo apt install switchboard-plug-networking


Elementary OS hangs when using libreoffice

This also happens on AMD desktops too. I cannot seem to pinpoint it, and it is rather annoying. I don't really have a solution, but try adding these repos to keep up to date with your software.

sudo add-apt-repository ppa:libreoffice/libreoffice-5-3
sudo add-apt-repository ppa:ubuntu-x-swat/updates

Those will keep LibreOffice Stable and you video drivers up to date. If the problem continues, try using your computer with your previous kernel. I had to lock mine at 4.11.12 last week as the update made my system unusable.


Nothing wrong in your steps, it happens to me as well, might be a bug.

But we need to install

  language-pack-gnome-ja
  language-pack-gnome-ja-base
  language-pack-ja
  language-pack-ja-base

While installing from terminal using apt-get getting dependency errors as in the bug.(I missed the bug page, I will add the link later)

I manually installed all the .deb packages,

First download all .deb files,

language-pack-ja

language-pack-ja-base

language-pack-gnome-ja-base

language-pack-gnome-ja

Now install in the order either from Software Centre or from terminal,

From terminal (I suggest use terminal, If you got errors use Software center)

cd ~/Downloads
ls #to avoid errors with file names
sudo dpkg -i [language-pack-ja deb]
sudo dpkg -i [language-pack-ja-base deb]
sudo dpkg -i [language-pack-gnome-ja-base deb]
sudo dpkg -i [language-pack-gnome-ja deb]
sudo apt-get update

EDIT:

If still not able to change to japanese, Again follow the procedure,

1) Hit + in Language&Region settings.
2) Find japanese or 日本語.
3) Double-click (This time should work, as shown in screenshot)

After that hit set language and set system language

You need to restart system to apply changes.

After restart, your language settings will be changed,

Any suggestions for a good laptop that runs well with Elementary?

Currently (2018), any new gen intel laptops have a good support with debian based distros (like Elementary), so it will run flawless.

The AMDs processors will run... well, the new ryzen is having a little trouble with debians distros as you can see here, but not something that would trouble (only if you are a dev or want go into advanced mode).

For video cards, I have a better experience with Nvidia (and it's drivers), but RADEON cards are good too.

  Anywhere to purchase one with Elementary installed?

I saw a laptop in the begin of the year, it was an Elementary OS powered laptop with some additional programs installed by default, but if I was you, I would buy something more powerful and plug it with a bootable elementary usb for a clean install.

  do I need to buy a Windows machine and dual boot?

No you don't, you can test it with a bootable USB drive without installing it OR you can install it in dual boot OR wipe it and make a full elementary os laptop.

I've found that this is caused by ibus-daemon program. If you have ibus running on startup, remove it or add a startup item to kill the ibus-daemon. You should be able to search in Slingshot launcher.


missed workspace manager on Version: 0.2.1 "Luna" ( 32-bit )

In Luna, workspaces are only accessible with a keyboard shortcut Super+S or by setting up hot corners. The multitasking view (and its shortcut) was added in Freya.

As an aside, Luna (0.2.x) no longer receives updates from elementary. You should upgrade to the latest release (0.3.2) to continue receiving updates from elementary.

How do I add support for the "hevc" format to VLC?

sudo apt-get update &&
sudo apt-get install vlc-plugin-libde265


From what I've recently read, Pantheon is able to be installed not only on top of Arch but also Fedora and OpenSUSE with a certain level of success.

The one thing to keep in mind is, that in some cases, the results of installing Pantheon on top of other distros may not give an end-user experience at the same level as using elementary OS. Until a distro like Antergos (Arch based) or Gecko Linux (OpenSUSE based) create an official or community spin, I personally, would stay away. Finding support within a user forum of a distro that does not officially support Pantheon or support it via a community release may prove to be difficult when the time to troubleshoot issues arrives.

If you're thinking of moving forward, doing an internet search using 'Pantheon Desktop Environment' plus the distro of your choice will get you moving in the right direction.

Good Luck!!!

Installing Juniper network connect in 64 bit elementary OS

Hi Have you tried the following mentioned on a ubuntu forum:

down vote
accepted
Solution for Ubuntu 11.10 or Later
Since Ubuntu 11.10 it shouldn’t be necessary anymore to use getlibs or some other workaround. The package system on 64 bit systems is now able to manage 32 bit libraries in parallel to the 64 bit libraries. You can even easily install complete applications with all their dependencies now!

Simply add :i386 to the name of the package you would like to install.

For example, I needed a 32 bit version of Java 7 and could install it (along with all its dependencies) simply by running:

sudo apt-get install openjdk-7-jdk:i386

How can I hide a user from the Welcome Screen?

I've had exactly the same question and I don't really understand the purpose why that user appears. But I just simply deleted it from the user accounts (hit the "-" button in left bottom corner).
The user is totally deleted - however I checked if that doesn't impact my virtualization after that : everything is OK (I'm using VMware workstation and GNS3).
Stupidly I didn't check some other possibilities (such as checking login shell, cf. https://askubuntu.com/a/906997/1148936 or https://askubuntu.com/a/940069/1148936) - which seems to be the preferred way to get rid of that.


Ahhh sorry, I was already able to find the solution. As long as I disable the setting that windows do not get maximized when its above 70%, the last size is now remembered !!

Solution:

To really launch Flameshot after successful installation:

Go to Applications menu > Graphics tab.
Locate Take Graphical Screenshot flameshot icon.
Right-click it and click Add to Dock menu item.
Right-click this icon in the Dock and click Keep in Dock menu item.
To launch Flameshot, use this icon. (You can delete 'Launch Flameshot' icon from the Dock.)

Indeed, for some reason, the icon named 'Launch Flameshot' apparently doesn't do anything at all, except for joyful jumping. (At least in v0.5.1 from Ubuntu's depository.) If this behavior is not a bug, then it is definitely a UI design flaw. If you'd like, you can report this issue to the developer @  https://github.com/lupoDharkael/flameshot/issues .


How do I fix/calibrate my screen colors?

I installed a custom colour profile, my blog about eOS has a section on that, https://medium.com/@SamMorrowDrums/elementaryos-one-week-in-f512553adde4#ecab

If you are happy with the colour profile in use on Xubuntu and Windows, you should be able to look at the settings to discover what profiles they are using, probably you can then export it to USB key / shared drive, and then use it on Elementary OS too. You can't screw things up too bad though, as you can just switch to another profile!

If you want to do it yourself, you can try installing gnome-color-manager or else you can look up your monitor and see if somebody has made a colour profile for your exact monitor, and try it out. If you want near-perfect colour replication, you will probably wish to avoid eye-strain reduction and night time profiles, as they will make changes to that might be less true, but more comfortable for those use cases.

A major producer of commercial colour profiles is Laptop Media you might also find ones on forums etc.

I don't have the reliability of light conditions, nor the trust in myself to get it right, so I have used a commercial one, and it has really improved things.

Hope this helps - installing a profile made a world of difference. I'm really enjoying looking at neutral white again!

About testing one desktop environment (DE) along another.

It will not give you a real experience of any of them.

Some DE are related to each other and may work together better than others.

As a general idea there is the Gnome-GTK family and the Qt-KDE family of DE.

KDE is one of its kind and I would not mix it with others.

But elementary OS-Pantheon, although GTK-based and Gnome-related, has become so specialized and special that I would never think installing a different DE on top of that. And even less would I install KDE, which is in itself so different.

About testing a desktop environment by itself.

Even installing a secondary DE and removing the first is a worst idea than installing in the first place an operating system having as default the very DE that you want to test. A default DE is already streamlined, adjusted, better put together, harmonized, complete.

If you want to test Pantheon, install elementary OS. If you want Unity, try Ubuntu. If you want to test KDE, try Kubuntu, Manjaro KDE, or even better Linux Mint KDE (my favorite KDE, considering what I said above).

About testing a different DE when I want to keep elementary OS.

There are a few options for testing a new OS or DE without touching your main elementary OS installation:

Use a virtual environment, through VirtualBox or VMWare inside elementary OS (as mentioned by a previous answer). CPU and RAM power is needed for comfortable use.
For the short term: make a live USB of the testing system and boot from that. Download the ISO and use a tool like Mintstick or UNetbootin. That USB can also be 'persistent' to remember changes made to the system. (After a while such persistent live installations may become instable, but they can work fine for enough time to satisfy your testing goals.  A good tool that I tried for that is LiLi in Windows.) -- It is a very good idea for any Linux user to have a few OSes at hand on live USB sticks for testing and emergency purposes.-- A live environment on USB (or even CD) is the ideal environment for testing in the sense of just taking a look at a system or desktop, especially for assessing the compatibility with your hardware.
For the long term:  do a separate installation on a new partition.

A separate partition of about 20-30 GB  can be created for the tested OS/DE. That's what I do, and that means using a multiple boot.

I find more easy to "test" a new Linux or desktop in this way than installing a DE on top of my favorite OS because I find it easier to get rid of it if I don't like it by formating the partition altogether than by removing the dependencies installed with the second DE.

Using Gparted from a live USB to shrink an old partition and than create a new one is not very difficult, but be sure you know what you do when you do that, and back-up your important data from your machine.

Also, keep in mind that removing the partition of the last installed Linux will normally remove the boot menu, which can be restored with a live USB using Boot-Repair. - On that, take a look here.

All this may seem tricky and indeed it needs some experience (which may come by small catastrophic occurrences :) but on the whole this will represent a much better and sane Linux experience than mixing elementary OS and KDE.

(If you select the new-separate-partition solution and need help, create a specific question on U&L, post the link under here and I will gladly try to give you a detailed answer.)


When you turn your computer on, press the esc key repeatedly after the bios screen until the grub menu comes up, use the arrow keys to highlight elementary os, press e to edit the boot command. Delete the words 'quiet splash $vt_handoff' from the line near the bottom that starts with 'linux' and press f10. This won't change it permanently and now you should see the error that is causing the problem.


kernel panic-not syncing: VFS: unable to mount root fs on unknown block(2,0)

Have the same problem and found out that page: https://www.linux.com/learn/how-rescue-non-booting-grub-2-linux

I used the commands from there:
during grub-menu just enter c for commandline, than do that:

set root=(hd0,1)

linux /boot/vmlinuz-   (now press TAB many times to find out whats the newest kernel-version. use that) and add root=/dev/sda1 at the end, the full-line should read as the following (but with the right kernel!!)
linux /boot/vmlinuz-3.13.0-29-generic root=/dev/sda1

to the same with the initrd (use the same init-rd-version as the kernel version!!)

initrd /boot/initrd.img-3.13.0-29-generic

boot

Now you should even be able to boot into Elementary OS


Cycle through all applications, across workspaces

Nope, without custom scripting, the OS only supports switching between windows in a workspace ("Switch Windows" in Settings > Keyboard) and switching between workspaces (org.pantheon.desktop.gala.keybindings cycle-workspaces-next), but not apps across all workspaces.

What you can do, however, is set "Show All Windows" in Settings > Keyboard > Shortcuts (also org.pantheon.desktop.gala.keybindings expose-all-windows), which will display every open window across all workspaces so you can choose the window you want.


Cannot use CTRL + X/C/V in Files on Dvorak layout

There was a commit a while ago to fix this but it has not been released yet.

Screenshot tool messed up system wide fonts

There is a feature that obscures the onscreen text for screenshots by switching the font, taking the screenshot, and then switching the font back.

The font obviously hasn't been switched back in this case and can be done manually with the following commands in the terminal:

gsettings reset org.gnome.desktop.interface font-name
gsettings reset org.gnome.desktop.interface monospace-font-name
gsettings reset org.gnome.desktop.interface document-font-name


In the terminal type this command and see what error or output it gives..share the result also

Single finger trackpad dragging inconsistent

If libinput driver installed by default feel too sensitive to point and click a small part of the screen,
 you can install synaptics driver instead.

sudo apt install xserver-xorg-input-synaptics

logout/in after package installation.


When booting into Elementary OS...NOT from a hard restart...no wired internet connection

The descripted issue might be caused by a lot of things.
I would like to suggest to start with setting the nic as managed by NM.
See here for some instructions.


The driver of your wifi card is problematic (almost all of Realtek are)
you can try this driver https://github.com/lwfinger/rtlwifi_new

This way:

# Make sure you have the needed tools
sudo apt-get install linux-headers-generic build-essential git

# Close the driver
git clone https://github.com/lwfinger/rtlwifi_new.git

# Enter in the driver directory
cd rtlwifi_new

# Compile
make sudo

# Install
make install

# And finally, reboot
sudo reboot

Can you start the system while holding down shift. Select your kernel and press e. Then remove quiet splash from the kernel parameters. This will allow you to see the boot output.


First install on a MacBook Air: black screen

That's probably a bug in nouveau driver introduced in kernel 4.15. It's still not fixed in 4.19 release.
Loki was on 4.14 which is working good.
See this: https://bugs.freedesktop.org/show_bug.cgi?id=106512

Could you specify which GPU exactly do you have?

Could you boot with nomodeset kernel parameter?
See: https://askubuntu.com/questions/38780/how-do-i-set-nomodeset-after-ive-already-installed-ubuntu

There are several workarounds:

To achieve these workarounds you'll have to boot with nomodeset kernel parameter.

Build and patch kernel with provided patch from source.
How To: https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
I have did it so If you wan't use nouveau, don't want to compile it by yourself and are ok with mine .deb binaries of patched kernel 4.15 I can upload them. Ask me If you are interessted. I recommend to do it by yourself.
Use nvidia's proprietary driver. Unfortunately the one in ubuntu repos is also bugged and you have to install official one manually which works without issues:
How To: https://github.com/elementary/greeter/issues/166#issuecomment-437144185

If you will be using nvidia-340 then you will be probably interessted also in this issue: https://github.com/elementary/gala/issues/253
