Removing the system-compositor-testing PPA

Should you have been using the system-compositor-testing PPA you will have to remove the PPA and it's content from your system prior to installing XMir from archive.

$> sudo apt-get update
$> sudo apt-get install ppa-purge
$> sudo ppa-purge ppa:mir-team/system-compositor-testing
$> sudo rm /etc/apt/preferences.d/50-pin-mir.pref

Then, follow "Installing from Archive".

Installing from Archive

Prior to landing Mir and related packages in the Ubuntu archive, we offered XMir via the system-compositor-testing ppa (ppa:mir-team/system-compositor-testing). As of August 9, 2013 XMir can be installed directly from archive via

$> sudo apt-get update
$> sudo apt-get dist-upgrade
$> sudo apt-get install unity-system-compositor
$> sudo apt-get install ubuntu-desktop-mir
$> sudo restart lightdm

Verifying that unity-system-compositor is running

You can check in 3 ways whether unity-system-compositor is running:

$> ps aux | grep unity-system-compositor
$> grep -i xmir /var/log/Xorg.0.log
$> ls -l /var/log/lightdm/unity-system-compositor.log

Removing unity-system-compositor


If you want to temporarily switch back to using on your system, run following commands:

$> sudo vi  /usr/share/lightdm/lightdm.conf.d/10-unity-system-compositor.conf

and add a comment to the second line:


and restart lightdm

$> sudo restart lightdm

If you want to enable XMir back again, you simply remove the comment:


and restart lightdm

$> sudo restart lightdm


In order to remove unity-system-compositor permanently from your system, run following command:

$> sudo apt-get remove unity-system-compositor
$> sudo restart lightdm
