I followed the instructions here to install Mir on my laptop on Saucy 13.10. Ubuntu Mir

It works well except for a known bug which causes the Laptop to go into low graphics after suspend.

So for a while I would like to go back to default without Mir. Ubsure how I can exactly get this done. What packages do I need to install to get back to default?

  • Have you done sudo apt-get purge mir-demos unity-system-compositor? Those are the packages you installed so removing them should fix the problem. – Seth Oct 26 '13 at 19:13
  • It also installed.libboost-program-options-dev libboost-program-options1.53-dev libboost-program-options1.53.0 libboost1.53-dev libgflags2 libglm-dev libgoogle-glog0 libmirclient-dev libmirclient3 libmirplatform libmirprotobuf-dev libmirprotobuf0 libmirserver-dev libmirserver7 libprotobuf-dev libprotobuf-lite7 libunwind8 mir-doc mircommon-dev xserver-xorg-xmir zlib1g-dev – sayth Oct 27 '13 at 8:54
  • Which I can apt-get autoremove. Lets see if system works after removing Mir. – sayth Oct 27 '13 at 8:55
  • Well its running after reboot and there is no unity-system-compositor listed so it must be on X. sayth@sayth-TravelMate-5740G:~$ ps ax | grep "unity" 1487 ? Ssl 0:00 /usr/lib/unity/unity-panel-service 1917 ? Sl 0:00 /usr/lib/libunity-webapps/unity-webapps-service 2163 pts/0 S+ 0:00 grep unity – sayth Oct 27 '13 at 9:00

You should be able to remove Mir with the following:

sudo apt-get purge mir-demos unity-system-compositor

then run:

sudo apt-get autoremove 

To remove any leftover dependencies. Reboot the machine.

To check if Mir was successfully removed run:

ps afx | grep unity-system-compositor

There should be no process with a name of unity-system-compositor.


Remove the session

sudo apt-get remove unity8-desktop-session-mir

Now remove the dependencies

sudo apt-get autoremove
