Elementary Loki GUI Volume Reduce is not working

Reinstalling alsa-base and pulseaudio did the trick for me.

sudo apt-get remove --purge alsa-base pulseaudio

sudo apt-get install alsa-base pulseaudio

Then, if necessary:

sudo alsa force-reload

and

reboot


Give this a try.

sudo apt-get install ubuntu-restricted-extras

If that doesn't work I'd recommend switching back to the default elementary fonts.


Is there a scaffolding for elementary OS app unit testing?

I should suggest to you to take a look at the elementary OS webpage,  at Developer Section:

Getting Started

You can find there how to get cmake modules to elementary-os development and how to write CMakeList files.


Everything you need is already inside /etc/apt/sources.list.d/ and /etc/apt/sources.list.

You don't need any extra PPA. If you want some interesting programs you can check the following:

Just installed EOS on my Chromebook. Working great! Just wondering about the best tweaks or programs that I may not know about
Apps for elementary
Which apps would you install after installing loki, to make it more awesome?

But be careful! Make sure the program you are trying to install works on your elementary OS version.


Do i need to install again drivers in dual-booting this OS?

You will still need to install the the same drivers on the same computer under elementary OS whether you install two OS (as in dual boot) or only elementary OS (replacing Windows 10).

Actually the system kernel underlying elementary OS is Linux which is completely separated from the Windows kernel and its drivers.

This might help in your case: with a working internet connection by ethernet, tethered or whatever means possible, please open a terminal and do:

sudo apt update
sudo apt install git
git clone https://github.com/kvalo/ath10k-firmware.git
sudo mkdir /lib/firmware/ath10k/QCA9377
sudo mkdir /lib/firmware/ath10k/QCA9377/hw1.0
cd ath10k-firmware/QCA9377/hw1.0
sudo cp *  /lib/firmware/ath10k/QCA9377/hw1.0
cd /lib/firmware/ath10k/QCA9377/hw1.0
sudo mv firmware-5.bin_WLAN.TF.1.0-00267-1  firmware-5.bin

Reboot and your wireless should be working.

If you downloaded Telegram from Telegram's website, it should be safe to run from anywhere on your system, including the home folder.

When you open Telegram, an icon should appear in the dock. You can right click that icon and select "Keep In Dock" to keep it in the dock.

In order to have Telegram appear in Slingshot (the application launcher), you'll need to make a desktop entry and place it in either /usr/share/applications/ or ~/.local/share/applications.

Or you can install Telegram from a PPA and it will do all of this for you.

To install Telegram from a PPA, open Terminal and run the following commands:

sudo apt install software-properties-common

sudo add-apt-repository ppa:atareao/telegram && sudo apt update

sudo apt install telegram

After you install Telegram from the PPA, you can easily add it to your startup applications.


Well... nice to see i'm not the only one having this problem. I installed MS fonts (msttcorefonts) and Calibri is not showing up. Pitty it had to be the most used font for MS Office docs...
Apparently Support for Type 1 fonts has been removed. Not sure if this interferes directly with that particular font, but you can try to paste a copy of the font to /usr/share/fonts.

I'll try to see if it works when i have the time.


elementary OS Freya 0.3.1 Mouse Problems

It might be the drivers (try reinstalling them)

But an OS doesn't care about the "single-click-sensitivity", it only checks if the mouse registers a keypress or not. So its probably a hardware issue.


No, not 0.3.2. The Loki beta does run fine though. You can install 0.3.2, but it probably won't detect your wireless card and you will have video issues, but if you can hardwire in, you can download the hardware enablement stack, then it should work, but even with that, I was still having issues with video performance. I'm sticking with Ubuntu 16.04.1 until Loki stable is released.

Here's how to download the Hardware Enablement kernel in 14.04 (which is what elementary 0.3.2 is based on).

Ubuntu 14.04 LTS - Trusty Tahr

The 14.04.2 and newer point releases will ship with an updated kernel and X stack by default. If you have installed with older media you can use the following to install the newer HWE kernel derived from 16.04 (Xenial):

DESKTOP

sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial libwayland-egl1-mesa-lts-xenial

MULTIARCH DESKTOP

If you run a multiarch desktop (for example, i386 and amd64 on amd64, for gaming or Wine), you may find you need a slightly more involved command, like this:

sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial libwayland-egl1-mesa-lts-xenial libgl1-mesa-glx-lts-xenial libgl1-mesa-glx-lts-xenial:i386 libglapi-mesa-lts-xenial:i386

Installing elementary OS alongside Windows 10

Ok so this got it working for me.

In the BIOS I kept only Launch CMS enabled (OpROM disabled).
Boot menu now has "Windows Boot Manager", the hard drive and the DVD drive.
With this combination I boot into Windows 10, install rEFInd and problem solved.

If you don't have Windows Boot Manager in your boot menu you have to disable CMS, save and after rebooting it will go directly into your BIOS again. Go to the boot menu and enable Windows Boot Manager, enable CMS and go back reading the previous paragraph.


grub-efi-amd64-signed package failed to install into /target/ During Installation

I never did find a way to install successfully without internet. But I enjoy Elementary OS so much that I found a workaround. Hint: you're going to need internet.
I had another PC with both wireless and ethernet capabilities. I shared its wireless connection via its ethernet port to the laptop I wanted to install Elementary OS on. Ran the installer and it completed successfully.


Have a look on "Conky". At the beginning it seems not to be easy to configure - but there are many templates you can use. Here you can find many templates - of course you can adjust them to your needs

Also usefull is "Conky Manager" (http://ubuntuguide.net/install-conky-manager-2-0-2-ubuntu-1404).

To have an idea how a conky can look like, see my desktop:

The red recangle shows the current up- / down-speed and the total size of uploaded / downloaded data. These values will be resetted after reboot.

Can not deactivate Alt+F7 XWindows shortcut (conflict with Netbeans)

Let's do it from gsettings:

gsettings list-recursively | grep \<Alt\>F7

This finds all actions set to that keybinding. For instance, mine:

org.gnome.mutter.wayland.keybindings switch-to-session-7 ['<Primary><Alt>F7']
org.gnome.desktop.wm.keybindings begin-move ['<Alt>F7']

Set any conflicts to blank ('') or another keybinding. For example,

gsettings set org.gnome.desktop.wm.keybindings begin-move "['']"

Voilà! And if you ever want to restore the default, use this format:
gsettings reset org.gnome.desktop.wm.keybindings begin-move

I believe that you are looking for Granite.Widgets.AboutDialog.

Nvidia drivers for Loki on an optimus system do not seem to work

The problem was actually something obvious.  I failed to turn off secure boot correctly.  I always thought it was odd that I never seemed to have to enter the password I set, not realizing I was passing over the spot to do it while booting.  The windows was so small on my screen to barely be legible.  When I did enter the password instead of pressing enter and passing over the prompt the drivers worked.


AppCenter - Prevent packages from updating

Have you tried blacklisting some specific versions of the packages? I guess this should help for at least a while!

This goes into the /etc/apt/preferences file.

Black Screen with an underscore at the top left of screen

I get the same thing but mine had to do with adding a 5600 xt and the radeon drivers in 5.3 not working. Installing 5.4 fixed the issue. Too do this boot to 5.1 and install ukuu and use it too install 5.4 I haven't tried 5.5.


Your intuition is right, reinstalling the OS is probably the easiest way out.  You have already made your /home partition separate so as long as you create the same username on the reinstall and point it to your existing /home partition, it should be super straight forward.   As you mention, just be sure to give the root partition 15GB (if not 20GB or 30GB).

If you're feeling adventurous, this is what I would try:

backup your data (and not just in your install, any critical data on this drive)
resize/reduce your /home partition by 20-30GB
create/format a new ext4 partition to hold a clone of your existing install in the 20-30GB freespace
use a tool like clone-ubuntu.sh to perform the clone (UPDATE: there seems to be a bug in "rsync -x" that doesn't make it skip your mounted /home partition. the workaround is to add "home/*" to the list of excludes in the script)

--exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found,/home/*}
verify you can boot to the clone (if your clone gets stuck on boot, this fix to update permissions of yr clone's root directory might work)
delete your old install
reallocate the freespace (perhaps extend your Win10 partition as you seem to be using up the space well)

I admittedly made mistakes using the script along the way (because I was using the script to migrate my install from HDD to SDD and it turns out the script is to clone installs to the same drive and thankfully didn't lose any data in the process - just lots of failed boots which I eventually was able to fix and learned a lot about the low-level pinnings of Linux!)

The only other thing I would watch out for is maintaining your dual-boot configuration.  but I feel if you got as far as getting dual-boot to work, you're good.

and if cloning doesn't work out for you, toss your old install and/or clone and install a fresh Elementary OS you intended.

good luck!


can I add a signature to mail in Elementary OS?

You can select Accounts/Edit account (crayon icon) at the bottom of the dialog. There is a checkbox to set a signature and a textbox to type your signature in:


Windows 10 no longer boots after dual installing elementary OS

Can you get directly into the boot menu directly when you reboot?  It might be F8.  If so, you should see windows boot manager as one of the options.  If you don't see it then something is not good.


How can I select a file without it opening?

Selecting files / folders works fine for me in Pantheon Files by either:

Using and clicking the checkmark at the top left of an icon to select one or multiple entries.
Clicking and dragging the mouse on an empty area to make a rectangular selection area.
Pressing the control key (ctrl) before clicking on an icon also allows to select one or multiple files.

If you only want to select one file you can also just do a right click and choose the action immediately.

To trash an item just press delete (del).

If you have problems with selecting files / don't like the default behaviour you can change the behaviour to open items on double click.


How to remove third-party icons from wingpanel in Elementary OS Loki?

I installed Dropbox from the AppCenter and it didn't fly. When I removed it, the red dash sign went with it. It was only after I tried to launch Dropbox and didn't fly that I removed it, so the indicator might be there for something you installed and is not working. I'm a newbie too, but I hope this helps.


How to prevent computer from sleeping or suspending

Figured this out.  The settings in System Settings->Power don't seem to make any difference, at least on my particular BIOS or motherboard or whatever.  However, this command will fix the problem and prevent the machine from ever sleeping:

You can install eOS Tweaks and there is a section called Cerberus. Wingpanel is added by default there so that whenever wingpanel is closed or crashes, it starts automatically.

You can create a custom theme that disables the bounce animation by following these steps:

You will first need to create a new directory for the custom theme. It is important that you give it a unique name that does not conflict with any existing theme names.

mkdir -p ~/.local/share/plank/themes/no-bounce

Assuming that you are using the default theme (elementary), make a copy of the theme to your user directory. Other default themes are located in /usr/share/plank/themes.

cp /usr/share/themes/elementary/plank/dock.theme ~/.local/share/plank/themes/no-bounce/

Edit the theme file.

scratch-text-editor ~/.local/share/plank/themes/no-bounce/dock.theme

Look for the line that starts with LaunchBounceTime. Modify it to LaunchBounceTime=0. Save the file and exit the editor.
Open your dock settings to change it to the custom theme.

scratch-text-editor ~/.config/plank/dock1/settings

Look for the line that starts with Theme. Modify it to Theme=no-bounce. Save the file and exit the editor.

Your dock icons should no longer bounce when you launch them.

The terminal plugin in Code follows the settings of the main Terminal application. To edit these settings:

Close Code and open Terminal.
Run sudo apt install dconf-editor, then close Terminal once the package is installed.
Open dconf Editor from the Applications menu.
Navigate to /io/elementary/terminal/settings

You can now edit any of these settings by clicking on them. If you're interested in changing the colors of the interface, you'll probably be most interested in background, foreground, and palette. Background is obviously the background color, foreground is the main text color, and palette is the colors of various other features (this might require some trial and error to figure out what each of them actually controls).

Note that to get these changes to update in the Code plugin, you may need to Disable it and Enable it again in Code's settings.


Fonts looks weird at Loki (and just in my user session!). How do I fix it?

I solved it after googling a while; this applies to all gnome based enviroments (at least according to this)

Just run the following lines on terminal, then reset the system normally. Done.

gsettings reset org.gnome.desktop.interface font-name
gsettings reset org.gnome.desktop.interface document-font-name
gsettings reset org.gnome.desktop.interface monospace-font-name
gsettings reset org.gnome.desktop.wm.preferences titlebar-font
gsettings reset org.gnome.nautilus.desktop font
gsettings reset org.gnome.desktop.interface text-scaling-factor

Only thing I don't understand is why the screenshot app (named just screenshot-tool) causes this. Seems like a bug to me.


Update error - signatures couldn't be verified because the public key is not available

For example, sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32. And run sudo apt update.

If that doesn't work or end up with error, please try to download and install keys manually from keyserver.ubuntu.com. Search your key string like this,

and copy every thing from the BEGIN PGP PUBLIC KEY line to END PGP PUBLIC KEY line. Save the text in a text file. Then please execute sudo apt-key add <file_name.txt>. For example if save the key contents in a text file name key, then sudo apt-key add key.txt. Now run sudo apt update from the terminal or go to appcenter and check for updates.

If this also didn't worked, please execute cp /etc/apt/trusted.gpg{~,} to  restore trusted.gpg from APT automatic backup. And then run sudo apt update to check if the issue still persists. If yes, please  execute sudo rm /etc/apt/trusted.gpg && apt-key update to delete and re-create it with the keys for the Ubuntu archive. Run update now.

If you face problem with appcenter, maybe there's no curated apps there, then please verify if your source list has elementary OS ppas. If your sources list don't have these,

[patches.list] ppa:elementary-os/os-patches
[elementary.list] ppa:elementary-os/stable
[appcenter.list] deb http://packages.elementary.io/appcenter bionic main

Please add them,

sudo add-apt-repository ppa:elementary-os/os-patches
sudo add-apt-repository ppa:elementary-os/stable

And add http://packages.elementary.io/appcenter bionic main at the end of the source.list file.

Please execute sudo nano /etc/apt/sources.list to open sources.list.
Hopefully this will fix your problem.


App store is only showing non-curated apps

It looks like planner is not only a Non curated app but it is free (no payment option) if you click on the icon there is an option for an Appcenter app and non curated (flathub) version of the app

Is syncing the photos library database between computers supported?

The Shotwell FAQ does not recommend it:

Can I access a Shotwell library across a network, possibly from multiple machines?
This is not recommended. Shotwell was not designed to support this use case, and the database can get into an inconsistent state. See this SQLite page on network access of a database file, in particular the problem of file sharing protocols not properly locking the database which can cause corruption.

Ticket #715764 tracks progress on making library network synchronization available in the future.


How can you install elementary OS without installing the bootloader?

To install elementary OS without installing the GRUB boot loader:

Boot up an installation media an select "Try elementary OS". This will load a live session instead of loading the installer directly.
Open Terminal and enter the following command. This will launch the installer with the option to not install the boot loader:

ubiquity -b

Continue installation as normal. The GRUB boot loader will not be installed.


No way to lock the CPU-frequency to a specific value

sudo apt-get install linux-tools-common

or set min:

cpupower frequency-set -d clock_freq

More in-depth information about cpupower can be found here: https://wiki.archlinux.org/index.php/CPU_frequency_scaling

You may also have to install additional kernel related packages since cpupower is only installed automatically in 3.4 and above.

While it used to be possible to scroll horizontally while holding down the Shift key while scrolling, that unfortunately doesn't work anymore.
There is a workaround that might do the trick for you using xbindkeys and a small script, though (as originally described here).This would allow you to toggle back and forth between vertical and horizontal scrolling by pressing Control + Right mouse buton.
Open a terminal and do the following:
1.Install xbindkeys:
sudo apt-get install xbindkeys

2.Create the toggle script and open it
>> ~/.toggle_script.sh
scratch-text-editor ~/.toggle_script.sh

3.Paste this into the file and save
#!/bin/sh
on()
{
  xmodmap -e 'pointer = 1 2 3 6 7 4 5 8 9 10'
}

off()
{
  xmodmap -e 'pointer = default'
}

if xmodmap -pp | grep -q '4.*6'; then
  off
else
  on
fi

4.Make it executable
chmod +x ~/.toggle_script.sh

5.Create the config file for xbindkeys and execute xbindkeys
echo $'\"~/.toggle_script.sh\"\n\tcontrol+b:3' >.xbindkeysrc
xbindkeys

You should now be able to toggle back and forth between scrolling modes by pressing
Control + Right mouse click
Please tell me if this works for you :)

As far as I know there is still an "Amazon App" pre-installed by default on current Ubuntu versions. However it is really just a link to the website and can be easily uninstalled. What you're referring to in your first quote is the Shopping Lens. It could also be easily uninstalled and in later versions of Ubuntu there was a setting to disable it, IIRC. However with 17.10 Canonical killed Unity and with it its lenses. Current Ubuntu uses Gnome Shell and there is no respective piece of software that does something similar. In Gnome Shell there is a similar concept called Search Providers, but there is no "Shopping Search Provider". It seems Canonical learned the lesson from the uproar that followed the introduction of the shopping lens.
elementary OS seems to be very concerned about the privacy of their users and doesn't come with anything like that pre-installed. elementary OS has an indexing service, but the collected data is only used for things like search and does not leave your computer / account. This can be disabled alltogether or on a filetype basis. See screenshot below.
elementary OS may come with some proprietary firmware files that are needed for some peripheral devices (like printers) to work at all. This is done by most Linux distributions nowadays. Other than that the OS itself should not contain any non-free software.


Where can I find the error logs when an application crashes?


Usually when i'm going to install fonts the system breaks down !

You should check the pre-install and post-install scripts inside the package, if you are installing a .deb package:

dpkg -x package.deb

You can install fonts this way:

sudo mkdir /usr/share/fonts/my-fonts
sudo cp /path-to-ttf-file /usr/share/fonts/my-fonts
sudo fc-cache -v


I had the same problem. I needed to change the schedule from "Sunset to Sunrise" to "Manual". I tested to change the hours and it worked again.

Hope that was helpful.


On what ubuntu/linux version is elementary based on

You can check

Can't type in my password when waking laptop from sleep mode

VexeDev,

Welcome to the forum.  Here is something you could try.

a. Open the terminal (Windows key + t)

b. Issue the command:

sudo nano /etc/default/grub

c. change

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.modeset=0"

d. Save and exit nano

e. sudo update-grub

f. Restart the laptop

If your Viao has the optional AMD Radeon HD 7550 graphics card (or similar option) you may need to install the correct graphics drivers, use systemctl to disable the fallback and then try again to get the suspend and resume to work.  I know this gave me troubles with a Razer Blade Stealth (2018) on Loki/Juno until I added the change to grub.

If that dosen't work, the workaround would be the following.

Go to System Settings -> Security & Privacy -> Locking
Disable the following toggle buttons:

Lock on sleep
Lock after screen turns off

Also, you could try to enable autologin as long as you do not mind the degraded level of security.

Go to System Settings -> User Accounts
Enable the following toggle button:

Log in automatically


Enabling context menu icons in Pantheon Files?

This would need changing Files code so cannot be done by the user.

There is an existing bug report about icons in context menu - #1542709 - so this feature may be implemented in future.


My elementary os is freezing very often, how can I identify and solve this problem?

sorry for the harsh "welcome" from the EOS. Anyway I would suggest to watch the system log for errors close to the seconds of the freeze (yes you need to write down the exact time when system freezes). Then try to search for the error. Maybe it will be descriptive enough to understand without search.
In my case the freezing was caused by faulty open source NVidia driver.


Slow Internet connection (WiFi) while using elementary OS Loki (Ralink RT3060)

There are some known issues between Broadcom and Ralink drivers. You can try to remove and purge the first with:

sudo apt-get purge bcmwl-kernel-source

If you hate reboot :P , you can try:

sudo modprobe -r rt2800pci
sudo apt-get purge bcmwl-kernel-source
sudo modprobe rt2800pci
sudo service network-manager restart


Why Firefox and Transmission are using so much memory?

You have only 2GiB of RAM. It's normal that your computer can't handle multitasking really well. You have a few options:

A) Buy some extra RAM. If you have a laptop you can also add more RAM sometimes.

B) Take it easy. Don't rush to open all the programs. Let them some time to load and save their data to the swap. You can also invest in a SSD to make your swap faster.

C) use more lightweight programs:

Instead of Firefox, you can use Epiphany (elementary web browser)
Use a Terminal version of Transmission. Here you have a how-to guide. You don't need to add that PPA listed on the guide. Everything is already on the official repos.


Why doesn't elementary OS include screensaver by default?

Not being one of the devs I can't really answer for them, but I suspect the reason is that screensavers are somewhat obsolete.

Unless you have a really old CRT display it is far better to allow the power saver to kick in instead. That saves the screen better than any screensaver and it saves energy.

There is nothing stopping you from apt installing the screensavers if you really want them though.


Wireless Connectivity Issues on Some Networks - Acer Aspire 1410 - Solved

You can try updating the wifi driver with a newer version from Wiki Kernel: iwlwifi. To your N-1000 card and kernel 3.19 you must download the next file:

iwlwifi 1000

After this, go to your  Downloads folder and open a terminal. Untar the file with:

tar -xvf iwlwifi-1000-*.tar.gz

Now you must copy the new firmware. Again from terminal:

sudo cp iwlwifi-1000-ucode-39.31.5.1/iwlwifi-1000-*.ucode /lib/firmware

That wireless card should drop occasionally with 11n connection,  so execute from terminal :

 echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf

Reboot the system and check your wireless connection.

I believe I've had this issue before when I was using an Nvidia card. The solution for me was (ensuring your graphics drivers are installed and up to date (this can be done from within the AppCenter, in the 'Updates' tab)) installing ffmpeg and the gstreamer packages. sudo apt install ffmpeg gstreamer1*. Let me know if this works for you, I hope it does, otherwise, this must be something else.

How do I change desktop + login background using terminal WITHOUT root permissions?

Hopefully someone can answer with the correct way to do this via gsettings, but under the hood the wallpaper contract is actually provided by a handy script called set-wallpaper. The following will change the background for your user on the desktop and login screen:

set-wallpaper <image-path>

I've just tested this myself - no root permissions needed.

The corresponding code can be found here. I can see the call to gsettings, but can't see anything else being done (though I haven't looked too hard) - so I'm unsure why just setting it via gsettings doesn't work.

EDIT: There's a copy_for_greeter() method in there which copies the image to /var/lib/lightdm-data/$USER, so I guess gsettings does work, but you need to ensure that you copy the image to somewhere where LightDM can access it.

So if you want to do this via gsettings then the following should work:

cp <background-image> $XDG_GREETER_DATA_DIR
gsettings set org.gnome.desktop.background picture-uri file:/$XDG_GREETER_DATA_DIR/<background-image>

However set-wallpaper does all of this heavy-lifting for you, so I'd recommend using that.


How to install genie effect of Mac OS in my elementary OS？

You cannot use compiz effects (not at all so this hack might not be useful) in Pantheon/Gala that is in the elementary OS desktop environement.


Full explanation here.

How do I fix this error when trying to install packages?

The script says "You might want to run 'apt-get -f install' to correct these". Have you tried running sudo apt-get -f install? It will attempt to correct broken dependencies.

My Boot freezes if my secondary drive is plugged in - Freya

The machine is attempting to book to your second drive. There are a few things that fix this:

Reorder Boot Devices in BIOS

By pressing the function keys, ususally F2 during startup (like, as soon as you power on), you can enter the BIOS. Look for a "Boot Order" section of the BIOS (usually one of the last tabs). Find your USB HDD, USB DISK, and/or your USB CD and move it/all three to the bottom of the list, so that your main disk (either SATA or IDE) is on top.

Remove "BOOT" Flag from the Drive

Usually when OS's are installed on a drive, they manually flag the drive as bootable with the BOOT flag. This is good, until you delete the OS. For many other reasons, your drive might have a BOOT flag on it.

Start up your and plug the drive in after it has booted.

Install gparted: sudo apt-get install gparted

Run gparted: sudo gparted

Look for you naughty disk on the upper-right corner of the screen (using a flashdrive for this example):

Select it, right-click the partition that says "boot" on the right side, and uncheck the "boot" flag:

Once unchecked, close the flag window and close GParted.

If you still have trouble, let me know how it goes and I'll see if I can help more.

Using Swift together with elementary frameworks?

There are some experimental tools, but nothing stable enough to build a production app with.

Any libraries specific to elementary OS can only be used with Vala. elementary OS is built on Gtk+, and there are experimental Gtk+ bindings for Linux. According to the documentation, "currently it implements only a small subset of Gtk+".

If you're looking for a way to build cross-platform apps that can run on elementary and other OSes, Electron seems to work well, and any language with Gtk+ bindings would probably be fine. But if you want to build a "native" elementary OS app, Vala is the way to go.

New B550 asrock steel legend ethernet 2.5G not working or being detected

Same problem here. I built a new computer a few days ago using another B550 chipset motherboard. My Gigabyte B550 Aorus Pro V2 also has the Realtek 2.5GbE LAN. I tried Hera 5.1.7 (20200814 build) and did not recognise the network adapter on boot.
I did the steps below and I managed to make it recognise the 2.5GbE controller.
From Realtek official page download the r8125 linux driver.
Extract and copy the r8125 driver to your computer with the B550 motherboard.
Install make and gcc packages from the bootable Elementary USB by issuing the command:
$ sudo apt-get install make gcc

After the packages are installed, open a terminal to the directory that contains the extracted drivers and give the command:
$ sudo ./autorun.sh

If everything went well, the drivers should be installed successfully. You can check if the driver is loaded by using the following:
$ lsmod | grep r8125

In my case the output was:
r8125        151552    0

If everything went well, at this point you should have access to the Internet. If not, try to check the README file in the driver's directory for extra guidance.


My system settings doesnt show full to Adminstration section

Maximize the Window
In elementary OS, you can double click the title bar to toggle an application as full-screen.
Double click the title bar and it should auto-fit to your screen.

Increase the Display's Resolution
If this has no effect, then your screen resolution is smaller than the minimum height of the System Settings window.
You might be able to fix this by increasing your screen's resolution from the Displays panel in System Settings, which fortunately is not cut off on your screen.
The Recommended System Specifications recommend a 1024×768 display.
I've tested with this resolution and the System Settings window fits correctly, but will be cut off on the next lower resolution for my screen, 800x600.

Click Displays.

This will display a preview of the displays connected to your system.

Click the settings wheel for your display.

Select a higher resolution from the Resolution drop down menu.

Click Apply.

In the dialog that appears, click Keep This Configuration to confirm the display's updated resolution.

How to integrate Dropbox with the file manager (Files)?

The elementary OS daily PPA contains a Dropbox plugin for Pantheon, which seems a little bit outdated but still works fine.

There are multiple ways to remove a PPA.

Option 1 :

Open the Applications menu ( super + space ) and search for Software and Updates

In the Software and Updates app, select the Other Software tab and select the desired PPA from the list. Click Remove to remove it.

Option 2:

In Terminal, use the -r or --remove flag to remove, similar to how the PPA was added. -r flag will only remove the said PPA. It will not revert any packages.

sudo add-apt-repository -r ppa:repository-name/ppa

Option 3:

PPAs are stored inside /etc/apt/sources.list.d. To list all the installed PPAs:

ls /etc/apt/sources.list.d

Note the name of PPA you want to remove (e.g.google-chrome.list), and remove it in Terminal using:

sudo rm -i /etc/apt/sources.list.d/google-chrome.list

Option 4:

In Terminal, use ppa-purge. It automatically downgrades any packages supplied by the PPA, and then removes the PPA.

sudo apt-get install ppa-purge
sudo ppa-purge ppa:repository-name/ppa


These are actually two commands, you might want to create a startup script ~/.local/bin/remap_capslock with the contents:

#!/bin/bash

xset r 66

set it to executable

chmod +x ~/.local/bin/remap_capslock

and run this script at startup


You can install manually that program with this :

sudo apt-get install software-properties-gtk
sudo apt-get install update-manager

it sounds like you are trying to do this while the system is running ... I think what you need to do is get another like distro to boot from that has gparted on it (or another partition tool that you can use) ... THEN run gparted on your disk (be careful) ... resize the partitions to your liking ... do NOT delete partitions or you will lose your data ... you want to RESIZE each partition ... so for your example, the 60 GB partition you would shrink to 20 GB then expand the other partition to 55 GB ... This is assuming that you are using less than 20 GB on the first

Can I make a dialog appear to ask what to do when I insert a DVD?

Ultimatelly, what I need is that whenever a DVD is inserted Frey asks what to do or automatically start a specific application.
And it seems that Freya actually lacks that functionality, according to this bug report.
So, for now, it seems that the answer to my question is... "No, you can't".


This could very well be caused by indicator-synapse (a 3rd party search indicator similar to Spotlight on OSX) which frequently poses a problem with Freya. Try to uninstall it by typing:

How can I install Elementary OS Freya 3.2 64bit on mac mini 1.1 flashed to 2.1?

The Mac Mini 1.1 was a Core duo, not a Core 2 Duo, and 32-bit only. It might work with a 32 bit version, but I'm guessing that the slight difference in the architecture might be the problem. From memory, that model Mac Mini didn't have a soldered processor, so you could take out the core 2 and put in a core 2 duo chip instead (check for compatibility first). It would still be 32 bit, though.


I can't install Elementary-Juno on my laptop

Basically, the first time you installed and didn't removed USB Drive due to which it booted again from USB Drive as the Boot Order was set. The second time you removed USB Drive earlier while it was in use hence it caused to display a lot of errors on the screen.

Please follow the following steps in order to get you system running:

Make USB Drive Bootable using Rufus and Elementary OS' ISO.
Restart the system and set boot order from BIOS to boot it from USB Drive
Restart the computer to boot from USB Drive
Install Elementary OS Juno
When it tells you to restart, DO NOT unplug the USB. Just restart and go to BIOS again before it boots from USB again.
Reset the Boot Order to boot from Hard Disk first.
Save Settings and restart
You are good to go.


Elementary OS DOES support touch. I have Dell XPS 15 with a touch screen and am running Loki without any special touch modifications. It all works as you would expect (including being annoying when someone touches your screen). I can click, drag, move and do so in combination with modifier keys. I'll be clicking on the "Post Your Answer" by touching the screen...


I don't know why you would have two icons, but you could hide one using AppEditor (https://appcenter.elementary.io/com.github.donadigo.appeditor)


How can I test the new 'recent' feature in Files?

First, we can check which version of Files you currently have (and where you're getting it from) with the following Terminal command:

apt-cache policy pantheon-files

You should see some information like the version you have installed, the version that's available to be installed, and versions that are available from your various software sources.

We can see here in Launchpad that the Recent feature was merged in at revision 1892. As of this writing, the version available in the daily PPA is revision 1922. You can see this inside the version string. First it contains the milestone version 0.2.2.1 then it says +r1922 which refers to the revision number in bzr.

If you saw that Files is available from the daily PPA when you ran apt-cache, but it was a previous revision number you can try updating your software sources with the following command:

sudo apt update

If you didn't see the daily PPA in your sources, you might want to make sure you have actually added it. Be warned that this is an unstable software source and it is intended for developers. You may experience breakage by using it. You can use the following commands to add it and refresh your software sources:

sudo add-apt-repository ppa:elementary-os/daily
sudo apt update

At this point, you should definitely see the latest revision of Files available from the Daily PPA when you run apt-cache with the above arguments. You can update through either the regular Software Updater app or with the following command:

sudo apt upgrade


Do you have Dropbox installed? In the last weeks there were several problems with its indicator. Have a look on How can I fix this strange icon in wingpanel? and mark this question as duplicate if this solves your problem.

If not the second answer can help you finding out what app is behind this indicator.

Here is the command (thanks to @bitseater):

dbus-send --type=method_call --print-reply --dest=com.canonical.indicator.application /com/canonical/indicator/application/service com.canonical.indicator.application.service.GetApplications | grep "object path"


Audio output stuck on device that is no longer connected

I suspected the pulseaudio was stuck for specific apps on the device that was no longer there (the TV) seeing that the system settings app could still output audio fine.

I installed Pulse Audio Control: sudo apt install pavucontrol .  And in here I could select the output per application.  Indeed the HDMI was still selected, changing it to the built in audio output fixed the issue.


Dock! Fullscreen games and then do you want into a new app

If I understand well you are trying to switch from a fullscreen app to another app aren't you? If it is the case, the Alt+tab would not help you because when an app goes fullscreen the os automatically moves it to another space but alt+tab is a keyboard shrotcut to swtitch applications on the current space only.

In this case what you want to achieve is to switch the space, and for this reason you have to use Super+Tab keyboard shortcut. Another options are Super+a, Super+s and Super+w

Super = windows like key on your windows keyboard or Cmd if you are on a mac. By default if you press only the Super key it triggers  a command that shows available keyboard shortcuts.


You need to change your keyboard layout to Portuguese (Brazil, eliminate dead keys). Follow these steps to change the default layout:

Open System Settings from the Applications menu.
Select Keyboard under the Hardware section.
Click the Layout button.
On the left side list box you will see a + button, click it.
From the Language drop-down box, select Portuguese (Brazil). From the Layout drop-down box, select Portuguese (Brazil, eliminate dead keys). Click Add Layout.
Highlight Portuguese (Brazil, eliminate dead keys) from the list box.

This should result in the proper keyboard layout.


Elementary does not work with my RTL8125 2.5GbE Controller

If possible, could you try connecting the machine to the internet via Ethernet over USB? This could be via adapter, directly from the router/modem, or tethering from a phone. Assuming this step works, fully update your system. The 5.4 kernel should include fixes for many RT devices. Once updated, make sure to restart, and if necessary, reconnect to Ethernet over USB and search for available drivers in AppCenter in the "Installed" tab or by using the sudo ubuntu-drivers autoinstall command.


Is Python pre-installed on elementary OS?

Yes, it does come installed by default.

Open a terminal session (press Supr+t or search for terminal in Slingshot) and enter:

$ python

This will give you access to Python 2.

If you need to work with Python 3, the command is:

$ python3


Is there any way to enable a screen keyboard when input is required?

System Settings > Universal Access > Typing > On-screen keyboard

More advanced settings like hiding it when not in use and layout are available when you click on "On-screen keyboard settings..."


Suggest you join their Slack-based chat from the white button on the left shown at their Translations page and ask for help. Open Source projects sometimes drop the ball, certainly not an issue limited to Elementary OS.

Partitions while installing Elementary OS

I find the partitions created by elementary os installer to be quite good. maybe you don't need the swap partition of you are not going to use hibernation , but other then that its OK.

BTW it's auto partitioning works for dual boot as well, u mean even if you are installing elOs as dual boot or can create the partitions for you

OS Freya only boots in recovery mode and doesnt hibernate

Boot using the recovery option in your grub.
Then open a terminal window and type:

sudo nano /etc/default/grub

Add nomodeset to GRUB_CMDLINE_LINUX_DEFAULT:

It should now look like this

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
GRUB_CMDLINE_LINUX=""

Save it with Ctrl+o then exit with Ctrl+x

Then update your grub using
sudo update-grub

Now you'll be able to boot without having to select the recovery option.


After trying other search engines and learning their syntax I was able to come across someone who had a similar issue on Ubuntu 12.04 and was able to fix it using

sudo dpkg --reconfigure --all

Which had me alter a few things like apache and ssl certs. After a reboot I don't seem to be having the issue anymore. I feel bad that I found the answer so soon after I had posted this question but I'm glad my last attempt to fix it was fruitful.


Can`t install Freya: "'grub-install /dev/sda' failed. This is a fatal error"

When you are trying to install elementary OS . The system gives you the option between installing automatically with Windows and advanced options where you can do the partitioning.

I suppose that you chose the second option, there you can find at the bottom and before you start installation,  an option asking you where you want to install the boot loader, but there you have to choose the disk and partition where you want to install it, try changing /dev/sda to /dev/sda1 (obviously only if /dev/sda1 is one of the Linux partition, not Windows one)

As an example, years ago i was installing Kubuntu and my computer never boot, i put my booteable sd-flash for reinstall but i didn't change the priority boot, and computer finally start, then i realize that i had installed the "start sector" in the sd-flash that was at the instalation " sda ".


Dual boot with Windows 10 - Windows resolution stuck at 800x600

Installing Intel Graphics driver along with nVidia in Windows fixed the issue. Actually I did this while trying to fix another issue where brightness control was not working in Windows - got the Intel drivers and installed it. That did fix the brightness control issue and as a bonus fixed the resolution issue with grub booting to Windows.


After a day of suffering, I finally managed to find a solution. These are the steps that you want to do if you have a similar problem:

Boot into Elementary OS live USB.
Mount root partition and proc, dev, sys subsystems of the installed OS.
Start bash with chroot /mnt/hdd /bin/bash command. /mnt/hdd is your mount.
Copy resolv.conf from live usb to mount.
Install Xserver package sudo apt install xserver-xorg-input-all.
Reboot.

My keyboard started working normally after that. I was following this answer.


You can create a .desktop to launch the launcher, its something like a shorcut in Windows.

To create it just write the following in a .desktop file

[Desktop Entry]
Name= (The name you wnt to appear)
Comment= (If you want something to appear when you put the mouse over it)
Exec= (route to launcher binary file)
Icon= (route to the icon you want for it)
Type=Application

Also, you may want to install https://appcenter.elementary.io/com.github.spheras.desktopfolder to be able to place things in desktop.


(solved) System freeze when pluging usb device or power cable

ok I fix the problem by upgrading to kernel 4.11 and blacklist the nouveau driver and install bbswitch and load it at startup via modules.conf


Why is ElementaryOS not processing the "V" key when capslock is toggled on?

Looks like it's related to a keyboard shortcut associated with this combination. Go to System Settings ->  Keyboard.

The tabs Layout and Shortcuts have all configurations for it.

Since I'm using WPS Office I had to install the IBus input method, that has also some configurable shortcuts. Check these out also if that's the case.

If this doesn't work, you can try dconf-editor:

sudo apt-get install dconf-editor
dconf-editor

Make a search for "key" and you'll get a list of key bindings.


System Settings > Sound > Line Out > check Mute


Strangely enough, on my PC Photos doesn't auto-import anything when I connect my camera. At the same time I couldn't find a preference inside the app which could be responsible for that behavior, let alone 'Do not convert my RAWs into JPGs please' option.

There's a preference called 'Watch library for new files' though, so try turning that off and see if it fixes the auto-import issue. If it doesn't, try your luck and report that to the eOS devs.


Can I connect to my VPN through GUI in Loki beta

Currently elementaryOS's Switchboard Network Plug doesn't support VPN connections.

This question have been previously asked before (No GUI Access to VPN Connections | OpenVPN | 16.04 Loki Beta Daily PPA)

Since then the Devs have been notified and currently there are 2 bug reports about this:

https://bugs.launchpad.net/switchboard-plug-networking/+bug/1416249
https://bugs.launchpad.net/switchboard-plug-networking/+bug/1427248

Keep in mind that Loki is still in beta and under development.

I can only advise you to check the above bug reports and mark them as "Yes, it affects me" under "This bug affects # persons. Does this bug affect you?"


Hotkeys do not work when switching to Russian

This should be fixed by entering the following commands to enable the hotkeys for the Russian keyboard layout:

sudo add-apt-repository ppa:attent/java-non-latin-shortcuts

sudo apt-get update

sudo apt-get dist-upgrade

restart unity-setting-daemon

After then you should restart your computer and check whether the hotkeys are working correctly.


Can I change the Multitasking view icon style?

Well, currently you cannot change these icons' size - they are adjusted automatically. However, if you're interested in this feature, you might consider to open a bug report on launchpad. The Multitasking View is part of Gala, the window manager used by elementary OS.


Latest update doesn't boot on my computer

Do you have any USB devices plugged into your computer when you booted? If you do, pull ALL of them out and try rebooting.
Elementary is based of of the Ubuntu kernel. Graphics support for Intel 4600 was added in the 13.04 version of the kernel. What elementary were you getting the USB error in, and which version did you restore back to?
You may want to try installing from the latest iso file from the elementary website here. Post back if it installs error free, or if you get similar errors.
The second picture you posted is of GRUB, the GRand Unified Bootloader. This is the software that actually loads the operating system. If you had other operating systems, then they would show up in that menu.
If you would like to hide the menu, boot into your install, open a terminal window, and type:
sudo scratch-text-editor /etc/default/grub

Then set the GRUB_TIMEOUT and GRUB_HIDDEN_TIMEOUT lines to 0.
Afterwards, run:
sudo update-grub

Does the snap package mean that we don't need to use super old softwares?

https://developer.ubuntu.com/en/snappy/build-apps/

Please do refer to this link to have a better idea. I believe it's the new way, similar to windows where one can easily install applications. However the old ways are also going to stick around.


To set the Windows key use:

gsettings set org.gnome.desktop.wm.keybindings panel-main-menu "['Super_L']"

If you don't like the change (as I), you can reset it with:

gsettings reset org.gnome.desktop.wm.keybindings panel-main-menu

I recommend you to check this tutorial, it has some neat tweaks for Loki.


Is there a version of Elementary based on a kernel that doesn't require a pae-capable CPU?

No, there is not a version of elementary OS that can be installed on a non-PAE CPU.


I don't have enough reputation to comment, so I apologise for putting this as an answer. I think you may have forgotten to post the error message you are getting?

I would run sudo apt update && sudo apt dist-upgrade if there is an issue with updating repositories.

Alternatively, if you have had a previous apt install fail, you can resolve it with sudo apt -f install which will often fix things.


To facilitate switching in the future you can add a default theme to the list:

mkdir -p ~/.local/share/plank/themes
ln -s /usr/share/themes/elementary/plank ~/.local/share/plank/themes/Pantheon

After that, the default theme will be named Pantheon.

Column View right click doesn't always work

This sounds like a duplicate of this bug:
https://github.com/elementary/files/issues/602

A fix for this has already been submitted for review, approval and merging.  Hopefully it will be fixed in the released version soon.


You got two errors trying to update.

First of all, an error with a bad signature. All repositories in Ubuntu are signed with a GPG key, to check its authenticity. Look at the key 40976EAF437D05B5 near the expression BADSIG. You must download the correct signature from the keyserver with this command:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5

To solve the problem with MergeList, make a copy of your apt-lists. From terminal, try:

sudo mkdir /var/lib/apt/lists_old
sudo mv /var/lib/apt/lists/ /var/lib/apt/lists_old

Now, remove the wrong lists:

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

and finally, recreate the apt-lists with:

sudo apt-get clean
sudo apt-get update


Firstly, try downloading UKUU (the Ubunutu Kernel Update Utility), and you can try to boot into some different kernels with minimum hassle. I successfully use 4.13.10. For 4.13 you would probably need this kernel patch, on top of driver.

Secondly, there might be other kernel modules that need to be enabled? ,

Finally, try filing an issue on the Github page: https://github.com/lwfinger/rtl8188eu/issues the fact you just need to run a command, as wifi radio is failing to switch correctly, sounds like something fixable.

You can do it via dconf-editor or via gsettings + terminal.

Open terminal and type in following:

# gsettings set org.pantheon.terminal.settings cursor-shape 'I-Beam'

To rollback run following:

# gsettings set org.pantheon.terminal.settings cursor-shape 'Block'

Open dconf-editor and navigate to org.pantheon.terminal.settings, open cursor-shape and set it to I-Beam.


Key repeat does not work after last OS update

It seems to be caused by a bug in the kernel module peaq_wmi as unloading it fixes the issue. This bug was intruced by the 4.13 kernel update. More people have had it. More info here: Arch linux forum, and the solution is here: unix & linux autorepeat does not work.

It seems that updating the linux kernel of elementaryOS will be mandatory once again (once the issue is resolved), in order to solve the issue for people incapable of fixing this issue.

Note: I am on Lenovo Yoga 500-14IHW


You can try in terminal:
sudo apt update
sudo apt upgrade
sudo apt dist-upgrade

If it will not solve the issue remove account from pantheon mail. Remove it via App Center. Then install Thunderbird in App Center.


I also tried some "scripting solutions" but finally I came to Insync. It's not free but in my opinion it's worth its prize.
Maybe you will give it a try.


Upgrade elementary to Ubuntu 15.04 'Vivid Vervet'

There are two reasons why it's a very bad idea to upgrade.

elementary OS 0.3 (Freya) is based on Ubuntu 14.04 (Trusty). It will almost certainly not work if you were to update to 15.04 - the packages do not exist for it.
15.04 will be EOL soon; end of life. This means it no will no longer get vital security updates, and so you would need to upgrade again to 15.10 before January 2016.
Based on the past release schedule, elementary OS 0.4 is likely to be based on 16.04 LTS and released around to a year after 16.04 is:

You should update to elementary OS 0.4 (Loki) when it is released. You should only update to new elementary OS releases, never an Ubuntu release as it has different software sources.

It's sensible to revert that change.

How to get rid of wrong player notification in sound popup?

These controls are not of the default Music player but the default audio controls of the elementary OS. They look like the controls of the already uninstalled player because the design of both is made the same. Every time you start audio from the browser for example these controls will appear.

I do not know how to remove them without problems for the os, but if the design of the icon is what botters you, you can change it using custom icon pack or just replace the icons with a name multimedia-audio-player.svg into /usr/share/icons/elementary/apps subfolders with a one that you choose.

Dell Inspiron 3543 Intel HD Graphics - Installation, display problems

You can try to install with nomodeset option, to prevent kernel load a wrong graphic driver.

Start your laptop from usb. When you see the grub boot menu, use your down arrow and go to "Install elementary OS " and rather than press enter key, press "e" key.

Now, you can see the boot options. Use your down arrow again and go to a line that look like:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Add "nomodeset" after "splash":

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Then press ctrl + X to boot the new grub entry.

After install elementary OS,  you will can configure your graphic driver.

Epiphany - Can't login to Google with new google sign-in page

Same for me with web-browser. Easy to fix with
sudo apt-get dist-upgrade


I was never able to get this working properly, but to my delight, the newest release of Elementary OS 5 Juno has an updated package of HPLIP (version 3.17.10) and it's working great with my printer.  So, not an answer for this particular question, but it's resolved with an upgrade.


It seems that the only way to remove disk encryption it to reinstall elementary os. Just make sure to back up all your files on an external drive before you do.

Sorry there is no other way :(


"apt-get upgrade" fails with errors (E: Encountered a section with no Package: header) and (W: Duplicate sources.list entry)

The lines that start with W: are warnings and not directly harmful. You somehow have the package source http://dl.google.com/linux/chrome/deb/stable/main (Google's repository for Chrome) listed twice. You can fix that from the Software Center once you've fixed your other problem.

The other problem is that one of the files that the package manager reads information from has invalid content. That's the file /var/lib/apt/lists/repo.steampowered.com_steam_dists_precise_steam_i18n_Translation-en. Given the name, this file contains translations of package descriptions. It's often distributed in a compressed form, but it needs to be in plain text form once it's downloaded to the /var/lib/apt/lists directory. The URL corresponding to this file is http://repo.steampowered.com/steam/dists/precise/steam/i18n/Translation-en which doesn't deliver anything now so I don't know whether the problem was on Steam's servers or on your machine. (Unless you need to be logged in to download that file?)

You should be able to fix this from the command line. Open a terminal. If you just want to fix the problem, run the command

sudo apt update

to download package lists again. This should remove the problematic file since there's nothing to download at this URL. If the file isn't removed, remove it manually (sudo rm /var/lib/apt/lists/repo.steampowered.com_steam_dists_precise_steam_i18n_Translation-en) — it only contains translations of package descriptions, so it isn't vital to the system anyway.

If you want to investigate what's going on, check the format of the file.

file /var/lib/apt/lists/repo.steampowered.com_steam_dists_precise_steam_i18n_Translation-en

If this says something about “compressed data”, it could be an APT bug or a temporary misconfiguration on Steam's servers. If this says that it's a plain text file, there was a problem on Steam's servers while building that file.

If the problematic file is downloaded again because that URL is in fact available for you, you may need to comment out the Steam package source until the problem is resolvd. If you want to do this, run

grep -r repo.steampowered.com /etc/apt/sources.list*

This will show a file name followed by a colon and some more text, the file name being either /etc/apt/sources.list or /etc/apt/sources.list.d/SOMETHING. Edit that file as the superuser (e.g. sudo nano /etc/apt/sources.list.d/steam.list) and add a # character at the beginning of the line(s) that starts with the word deb. To reenable the source, remove the # character.

After running apt update with no errors and getting rid of the problematic file, the Software Center and the apt* command line tools should work again.


The problem is most likely the file ~/.local/share/nasc/nasc.sheets

Start NaSC again after you deleted this file.


How do I restore the elementary OS Freya original sources list?

Check that you don't have any elementary OS repositories launching Software & Updates  from Slingshot or terminal:

software-properties-gtk

If you have checked it, open a terminal and execute:

sudo add-apt-repository ppa:elementary-os/os-patches
sudo add-apt-repository ppa:elementary-os/stable
sudo apt-get update

Try to check now for new updates with:

sudo apt-get dist-upgrade

That's all.

About system tray icons. In release-juno, elementaryOS dropped the support of the old Ayatana Indicators

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

Any confirmation on a Ryzen 5 2400 with Elementary OS?

I am running Pantheon Desktop on fedora 30. And it runs really great. My CPU is a AMD Ryzen 5 1600X (6 core). My Current kernel version is 5.1.8-300. I have used for a long time, maybe over 10 years, only ubuntu and manjaro. But Fedora 30 is really surprising me a lot. And I think to switch to fedora. The Pantheon desktop is running faster and smoother as like in Elementary OS 5.0. The Pantheon desktop is still not completely integrated, but for my requirements it's good enough.

Back to your question
My AMD Ryzen 5 1600X CPU is absolutely Elementary OS 5.0 an Fedora 30 (GNOME + Pantheon) compatible. Why should the a bigger CPU from AMD not be compatible?

Cheers Chris

If you enabled the desktop icons by Nautilus (How to enable desktop icons and right click in Elementary OS Freya?), you can do the following:

cd ~/.config/gtk-3.0
nano gtk.css
add the css: .nautilus-desktop.nautilus-canvas-item {color: #ffffff;text-shadow: 1 1 alpha (@fg_color, 0.8);}
restart session

Change the color as you want.


OK so here's what I would do (I'm also a fairly newb):

open Scratch text editor and create a new file.
Paste the following into that new file:

[Desktop Entry]
Version=1.0
Terminal=false
Type=Application
Name=GNS3
Comment=Description of program- whatever you want
Exec=gns3 start
Icon=/path/to/gns3icon
Categories=

Note for the Icon= line: I usually will save the icon in /home/your-user-name/.local/share/icons (After searching online for the icon usually, unless you already know where it is, then just copy it to the .local/share/icons folder)

Then save it as gns3.desktop in /home/your-user-name/.local/share/applications/

It should now be in your Applications menu. Let me know if that works.

If you have, by any chance, tried to install Synapse / indicator-search then this could be the reason as some versions are known to break WingPanel.

You should be able to uninstall it by typing (in Terminal):

sudo apt-get remove indicator-synapse

Restart and check if it has any effect.

If yes and you added a PPA just for this, you should also remove the PPA.


Deleting/moving desktop entries in /usr/share/applications or /usr/local/share/applications has one major downside:

Everytime one of your "hidden" applications gets an update, it will reappear in Slingshot.

There is a more convenient and permanent way to hide your applications:
Install and run menulibre from the official repositories. Within this application you can enable Hide from menus to hide every entry, which you want to disperse.

Unlike Zzzach...'s solution MenuLibre doesn't remove the hidden entries, it creates a copy in your local application entries folder ~/.local/share/applications and adds the following line:

NoDisplay=true

The global desktop entry stays untouched and gets overriden by your local copy. An update of your hidden application will only overwrite the global entry, so this application will stay hidden.

But I have to agree with you, a hide right click menu entry would be the most convenient way :)


First, delete every nvidia driver related package you have tried to install. Then do the following:

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


How to install current packages for elementary OS development/build support?

You're not going to be able to build the latest versions of everything on Freya.

At the moment, we're developing the next version of elementary OS on an Ubuntu Xenial base. You'll need to do the same. You can get the latest builds for Ubuntu from their website here.

If you're new to development on elementary OS, I would recommend taking a look at our Getting Started Guide. It'll give you a well-rounded overview of using Launchpad/bzr, simple Gtk+ development, CMake, gettext translations, and even Debian packaging.


Welcome to the Elementary OS forum.

Just to conform that the standard user account has the proper privileges to their own home directory please try these steps.  Go to Applications -> Terminal (or Win+T).

Type the following command:

sudo ls -al "/home/userID"

Where userID is the name of the standard user account that you created.  The listing provided will show you the first level of the standard user's home directory.  You should see that userID and groupID are identical for everything except for the second line (that ends with ..), it should list the user as root and the group as root.

There are many additional levels to the home directory where privileges could be changed, but starting with the first layer is a good place to start.

Other solutions include
While in Terminal type the command:

df -H

Make sure that none of the Use% is near to 100%.

Finally, go to System Settings -> User Accounts
Then create another standard user by clicking on the '+' icon in the lower left corner of the window.  Then try to log in as that user.

When I use my laptop on public networks, I always use my non-privileged account for security reasons.

Good luck!


Eclipse Mars freezes after splash screen

It's a bug in the SWT porting on GTK3. There is no real solution, but there is a workaround by forcing Eclipse to use GTK2.

I assume your Eclipse folder is /opt/eclipse and that you don't have write permissions in this folder. Please change the commands, if your set-up differs.

There are two ways to apply this workaround, a long and explanatory way, and a short one for the lazy ;)

1. Modifying eclipse.ini by hand

You need to open eclipse.ini in your Eclipse folder:

sudo -i scratch-text-editor /opt/eclipse/eclipse.ini

and add the following lines:

--launcher.GTK_version
2

It's important to add these lines before --launcher.appendVmargs, otherwise Eclipse will crash.

2. Using the command sed

An easier way to make these changes is to use sed. Copy&pase this command in your terminal and press Enter:

sudo sed -i '/--launcher.appendVmargs/ i \--launcher.GTK_version\n2' /opt/eclipse/eclipse.ini

Your Eclipse should work properly from now on.

Firefox GTK3 build(s) not usable/working

The solution is to install gtk3-nocsd package and to preload the small library provided by it by adding something like:

env LD_PRELOAD=/usr/lib/gtk3-nocsd/gtk3-nocsd.so

in front of the command line launching your firefox.

The package is found in this repository.

More details here.

My own configuration for Firefox looks like this:

Edited
A quicker way, without installing a package is to pass in the command line the option GTK_CSD=0 which is supposed to have the same effect (thanks to @augenleet I found the information in this Mozilla ticket). However, the "white text" issue still remains, though.


Actually the answer is more of "yes and no". There is a lot of system libraries that has been specifically modified for the elementary OS look & feel (libgtk, etc.). You can install any Ubuntu or even third party applications most of the time, however.

You can find some more information (it is about PPAs but might be applicable to other third party apps as well) at Can I safely install any PPA for Ubuntu on elementary?

Screen flickering solution


How do I add images to select as the desktop's background?

You can drag&drop them into the backgrounds window and they will automatically appear in the listing.
All the drag&dropped pictures are being copied to ~/.local/share/backgrounds/.


Will there be a version of Juno based on Ubuntu 19.04 or 19.10 before 20.04 LTS?

elementary only bases itself off the LTS versions of Ubuntu to reduce the development workload in continually revalidating against newer library and base package versions. So yes, the next major elementary version will be based off the next LTS release.

It may be possible to attempt upgrades yourself, just in the same way as it may be possible to run the pantheon desktop environment on newer versions of Ubuntu or other distributions. But you'd be doing so with no expectation of support from the elementary developers.

However, there are often minor releases that come with updated kernels and drivers (based off the Ubuntu HWE stack) to keep up with newer hardware. For example, Loki had a 0.4.1 release that included this and Juno is expected to have a 5.1 release with the same.

Also, with Flatpak support coming in AppCenter, it ought to be possible to keep user facing applications more up to date easily. So an older base OS will matter less.
