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?
sudo apt-get purge mir-demos unity-system-compositor
? Those are the packages you installed so removing them should fix the problem.
