Reason: Besides a mention to an alternative package, this page is entirely about the 2014 Skype client, which has progressively worse compatibility with other clients. (Discuss in Talk:Skype#Skype_legacy_version_incompatible_with_new_version)

There are two official Linux versions of Skype available:

  • The new Skype for Linux (released 2016-07-13, currently in beta): see #Skype for Linux
It is basically the web version in a wrapper. Group video chat is not yet working.
Legacy Skype does not support calling to some newer clients.[1]

Alternatively, you can use the web version at It has working voice and video chat (at least on Chromium/Chrome and Firefox), but group video chat is not yet working.


Skype for Linux

There is a new Skype for Linux Beta, which is basically the web version at in a wrapper. It has working text, (group) voice, and video chat (group video chat is not yet working).

Install it with the skypeforlinuxAUR or skypeforlinux-binAUR package.

Legacy Skype


Install the skypeAUR package.

Running Skype is just as easy. Type skype into a terminal or double-click the Skype icon on your desktop or in your DE's application menu.

Skype sound

Skype requires PulseAudio for voice communication and does not support plain ALSA.

Alternatively, if you do not want to use PulseAudio, you can install apulseAUR (and lib32-apulseAUR for x86_64 users) from the AUR, which emulates PulseAudio. Then execute Skype with:

$ apulse skype

or for x86_64:

$ apulse32 skype

See ALSA/Troubleshooting#Setting the default microphone/capture device and following sections if the microphone is not working.

If everything is functional, modify the desktop entry in /usr/share/applications/skype.desktop so that the Exec line reads:

Exec=/usr/bin/apulse32 /usr/bin/skype  %U

Restricting Skype access

There are a couple of reasons you might want to restrict Skype's access to your computer:

  • The skype binary is disguised against decompiling, so nobody is (still) able to reproduce what it really does.
  • It produces encrypted traffic even when you are not actively using Skype.

See [2] for more information.

Restrictions can be implemented in a number of ways, with varying ease and security. It is possible to run Skype in a container, run it as a separate user, or use the Mandatory Access Control functionality available in the Linux kernel.


Warning: systemd-nspawn provides the most straightforward way to run an application in a separate environment, however it is not considered to provide a fully secure setup.

The following script will create a container in /mnt/stor/vm/skype and run Skype from there on each subsequent run. Fetching the default pacman config is necessary for 64-bit systems with multilib enabled, but be careful in case you have custom repositories enabled. Note that sound and video may be broken with this method.

 set -e
 if [ ! -d "$DEST" ];then
     sudo mkdir -p "$DEST/var/lib/pacman/";
     sudo mkdir -p "$DEST/etc/"
     sudo curl -o "$DEST/etc/pacman.conf"
     echo sudo skype | sudo pacman --arch i686 --root "$DEST" --cachedir /var/cache/pacman/pkg --config "$DEST/etc/pacman.conf" -Sy - --noconfirm
     sudo systemd-nspawn -D "$DEST" groupadd skype
     sudo systemd-nspawn -D "$DEST" useradd -g skype skype
     sudo mkdir -p $DEST/home/skype/.config/pulse
     sudo cp ~/.config/pulse/cookie $DEST/home/skype/.config/pulse/
     sudo cp ~/.Xauthority $DEST/home/skype/
     sudo chmod 755 -R $DEST/home/skype/
     sudo chown -R 1000:1000 $DEST/home/skype/
 sudo systemd-nspawn -D "$DEST" --bind=/tmp/.X11-unix --share-system sudo -u skype env DISPLAY=:0 PULSE_SERVER=desktop skype


Warning: Running Docker has its own set of security implications and caveats. Read the main Docker article for more information.

Install Docker and feel free to explore Docker Hub for Skype images prepared by users.

A tried and tested image is sameersbn/skype (hosted on Github). It uses X11 and PulseAudio unix domain sockets on the host to enable audio/video support in Skype. A wrapper script mounts the X11 and Pulseaudio sockets inside the container. The X11 socket allows for the user interface to display on the host, while Pulseaudio socket allows for the audio output to be rendered on the host. /dev/video0 is also mounted.

Container has access to ~/.Skype and ~/Downloads directories on your host system. Wrapper scripts are installed into /usr/local/bin.

For installation use upstream instructions.

Use Skype with special user

Tango-edit-clear.pngThis article or section needs language, wiki syntax or style improvements.Tango-edit-clear.png

Reason: This section needs revising both in content and style (Discuss in Talk:Skype#)
Warning: As of version 1.16, Xorg runs as a regular user. This means a special user has no access to X. The following approach only works when enabling root for Xorg; see Xorg#Rootless Xorg (v1.16).

A special user can be used for running Skype within one's normal environment. Permissions will have to be set to ensure your home directory is not readable by the special Skype user (see File permissions and attributes).

An AUR package, skype-secureAUR exists that will run skype as a separate user ("_skype") cleanly. It is heavily based on the information in this section.

Create a new group for the skype user:

# groupadd skype

Then we have to add the new user:

# useradd -m -g skype -G audio,video -s /bin/bash skype
Note: Maybe you need to add "skype" user to "pulse-access" and "pulse-rt" groups. But it works fine with "audio" and "skype" groups only.

Now add the following line to /home/skype/.bashrc:

export DISPLAY=":0.0"

At last we define the alias (e.g. in ~/.bashrc):

alias skype='xhost +local: && su skype -c skype'

Now we can start Skype as the newly created user simply by running skype from the command line and entering the password of the user skype.

If you are tired of typing in the skype user's password every time, make sure you installed the sudo package, run visudo then add this line at the bottom:

%wheel ALL=(skype) NOPASSWD: /usr/bin/skype

And use this alias to launch skype:

alias skype='xhost +local: && sudo -u skype /usr/bin/skype'
Note: If you forget the xhost command, Skype may fail with a "No protocol specified" error on stdout.

I noticed that the newly created user is able to read some of the files in my home directory because the permissions were a+r, so I changed them manually to a-r u+r and changed umask from 022 to 066.

In order to restrict user "skype" accessing your external drive mounted in /media/data for instance, make sure first that "skype" does not belong to group "users" (if you used the default group "skype", everything should be fine), then change the accesses on the mount point:

# chown :users /media/data
# chmod o-rwx /media/data

This way, it is ensured that only the owner (normally "root") and "users" can access the specified directory tree while the others, including "skype", will be forbidden.

Access Pulseaudio controls when using Skype as a different user

As the "main-user" copy /etc/pulse/ to ~/.pulse/ and add:

load-module module-native-protocol-tcp auth-ip-acl=

As the skype user, create ~/.pulse/client.conf and add:

default-server =
Open URLs in your user's browser

When one clicks URL in chat window, skype execute xdg-open to handle it. By default xdg-open uses default web browser for skype user environment. In order to open links in your user's browser perform next setup.

  • Sudo should be installed and properly configured.
  • Current example uses firefox as preferred browser.
  • Do not forget to adjust your_user to proper value.

Log in as skype user:

$ sudo -u skype -i

Create local preferences dir:

$ mkdir -p ~/.local/share/applications

Create /home/skype/.local/share/applications/firefox-sudo.desktop file:

[Desktop Entry]
Exec=/home/skype/firefox-wrapper %u

Set firefox-sudo.desktop to manage HTTP and HTTPS URLs:

$ xdg-mime default firefox-sudo.desktop x-scheme-handler/http
$ xdg-mime default firefox-sudo.desktop x-scheme-handler/https

(Optionally) add FTP handler:

$ xdg-mime default firefox-sudo.desktop x-scheme-handler/ftp

Create /home/skype/firefox-wrapper script (adjust your_user):

DISPLAY=:0.0 HOME=/home/your_user sudo -u your_user /usr/lib/firefox/firefox -new-tab $1

Make it executable:

$ chmod +x ~/firefox-wrapper

Now as root user open /etc/sudoers:

# visudo

And add permission for skype user to exec user's browser (adjust your_user):

skype ALL=(your_user) NOPASSWD: /usr/lib/firefox/firefox -new-tab http*, /usr/lib/firefox/firefox -new-tab ftp*
Access received files

By default skype stores received files with 600 permissions (only owner can access them). One may use incron to perform automatic permission fix upon downloading.

Note: This example assumes that you configure skype to save received files into /home/skype/downloads

Make skype home dir and download dir accessible:

# chmod 755 /home/skype /home/skype/downloads

Install incron with the incron package, and enable and start incrond using systemd. Open incrontab for root user:

# incrontab -e

Add incron job:

/home/skype/downloads IN_CREATE chmod 644 $@/$#

Save changes and exit incrontab editor.

To test incron in action just enter skype download dir and create test file:

# cd /home/skype/downloads
# install -m 600 /dev/null test.txt
# ls -l test.txt

File permissions should be 644 or -rw-r--r--

(Optionally) link skype download dir into your home dir:

$ ln -s /home/skype/downloads ~/skype_files


See the AppArmor page for how to set up AppArmor.

The userland tools for AppArmor come with a collection of example profiles. Skype is amongst them. Copy this to the directory where AppArmor profiles are stored.

# cp -ip /usr/share/apparmor/extra-profiles/ /etc/apparmor.d/

For whatever reason, the profile is not complete. You may wish to modify it further. Here is an example for Skype 4:

#include <tunables/global>

/usr/bin/skype {

  deny owner @{HOME}/.mozilla/** r,
  deny /sys/devices/virtual/dmi/** r,
Note: This example assumes that Skype is configured to save received files into ~/Public. Feel free to change it to any folder you like.

To use the profile, first be sure securityfs is mounted,

# mount -t securityfs securityfs /sys/kernel/security

Load the profile by the command,

# apparmor_parser -r /etc/apparmor.d/

Now you can run Skype restricted but as your own user. Denials are logged in messages.log.

  • After finishing editing reload TOMOYO config files by executing these commands:
# tomoyo-loadpolicy -df < /etc/tomoyo/domain_policy.conf
# tomoyo-loadpolicy -ef < /etc/tomoyo/exception_policy.conf

Skype is now sandboxed.

Please note that this config is generated on 64-bit Arch system, and some of your ioctls and library paths may differ from mentioned above. So in order to fine-tune TOMOYO config for your Skype start tomoyo-auditd.service.

Then go to /var/log/tomoyo folder and start watching reject_003.log:

$ tail -f reject_003.log

The output of this command will show you rejected actions for Skype, so you will be able to add them to domain_policy.conf file if needed.

See [3] for a detailed guide to TOMOYO configuration.


GUI does not match GTK Theme

See Uniform look for Qt and GTK applications for information about theming Qt based applications like VirtualBox or Skype. Also, you may need to install the lib32-gtk-enginesAUR package.

Test call fails

Call to Echo Test Service can fail with error "call failed" when the user profiles are usually corrupt. Solution is to remove the profile and file and re-add your account in Skype as seen in Ubuntu Forums.

 # rm ~/.Skype/ -rf

No video with GSPCA webcams

Firstly, remove the Skype configuration directory. Otherwise preloading V4L libraries (see below) will not help, because old settings will override preloaded libraries. Note that all personal account settings will be lost.

rm -rf ~/.Skype

For i686, install v4l-utils, userspace tools and conversion library for Video 4 Linux, and run Skype with

LD_PRELOAD=/usr/lib/libv4l/ skype

to start Skype with v4l1 compatibility.

For x86_64, install lib32-v4l-utils from [multilib] repository and run Skype with

LD_PRELOAD=/usr/lib32/libv4l/ skype

To make it running from DE menus and independent of Skype updates, you can add alias (e.g. in ~/.bashrc):

alias skype='LD_PRELOAD=/usr/libxx/libv4l/ skype'

where libxx should be edited as appropriate.

No video with Compiz

Try launching Skype setting an environment variable like this:


Skype does not use a GTK+ theme, even though other Qt apps do

Recent versions of Skype allow you to change the theme via the Options menu. However, selecting the GTK+ option may not work properly. This is probably because you do not have a 32-bit theme engine installed. Try to find the engine your theme uses in the multilib repository or the AUR. If you have no idea which engine your theme is using, the easiest fix is to install lib32-gtk-enginesAUR. This does however contain quite a lot of packages, so the best would be to find and install only the needed package.

Note: You may not have to install lib32-gtk-enginesAUR. First try if the following steps work for you if you only install lib32-gtk2 and a GTK+2 theme respectively. See also the forums.

Once installed, it will still not work unless you have a 32-bit version of GConf installed. You could build and install lib32-gconf if desired, but there is an easier workaround. First, create or edit ~/.gtkrc-2.0 so that it contains the following line:

$ gtk-theme-name = "My theme"

Replace My theme by the name of your theme, but leave the quotes. Second, run Skype like this:

$ export GTK2_RC_FILES="/etc/gtk-2.0/gtkrc:$HOME/.gtkrc-2.0"
$ skype

The GTK+ theme should now appear correctly. You can make this permanent either by running Skype from a script containing the above 2 lines, or by exporting GTK2_RC_FILES in ~/.xprofile or ~/.xinitrc, depending on how you start X.

If you cannot change the theme in the Options menu, run Skype using the following command:

$ /usr/bin/skype --disable-cleanlooks -style GTK

If you wish menus within desktop environments to load Skype with a GTK+ theme by default then modify the 'Exec' line of /usr/share/applications/skype.desktop so that it reads:

$ Exec=/usr/bin/skype --disable-cleanlooks -style GTK

Similarly if you have set Skype to autostart then modify ~/.config/autostart/skype.desktop in the same way.

No incoming video stream

If skype shows a black square for the video preview, but something else (like xawtv -c /dev/video0) shows video correctly, you might need to start Skype with:

export XLIB_SKIP_ARGB_VISUALS=1 && skype

Another possible workaround is to preload

LD_PRELOAD=/usr/lib/libv4l/ skype

A further alternative is:

cd /usr/lib/lib32/libv4l && skype;

Monster/low-octave "growling" distortion over mic

Some users with newer kernels are experiencing a monster-like growling distortion of their sound stream on the other end of Skype. This can be fixed by creating a dummy ALSA device or by removing ~/.Skype/shared.xml. See for more information.

Crackling/noisy sound (mainly using 64-bit OS)

Solution 1

With root privileges, edit the /usr/bin/skype script to add the PULSE_LATENCY_MSEC variable, changing this line:

exec "$LIBDIR/skype/skype" "$@"

to this:

PULSE_LATENCY_MSEC=60 exec "$LIBDIR/skype/skype" "$@"
Solution 2

Edit /etc/pulse/ and change the following line

load-module module-udev-detect


load-module module-udev-detect tsched=0

See also: PulseAudio/Troubleshooting#Glitches, skips or crackling.

Skype sounds stops media player or other sound sources

You can try commenting out the following modules in /etc/pulse/

#load-module module-role-cork

Finally you have to restart pulseaudio:

$ pulseaudio --kill
$ pulseaudio --start

If restarting does not solve the sound problem try to log out and log in again.

If that does not help, you can try changing flat-volumes to no in /etc/pulse/daemon.conf.

flat-volumes = no

If that still does not work, you can manually unload the module:

$ pactl unload-module module-role-cork

You are already signed in on this computer

If Skype is closed without the dc.lock file being deleted, it will fail to log back in.

To fix this, close Skype and run:

$ rm ~/.Skype/shared_dynco/dc.lock

Empty white screen window

If you get a white empty window when launching skype, try to autologin like this instead:

$ echo username password | skype --pipelogin

Skype doesn't output any sound after upgrading PulseAudio

Currently, Skype doesn't work PulseAudio 9.0 enable-memfd option, you have to make sure it's disabled in /etc/pulse/daemon.conf.

Skype plugin for Pidgin
