Revert back to Nouveau drivers [duplicate]
Solution 1:
One of the following should work:
sudo apt-get remove --purge nvidia-current
sudo apt-get remove --purge nvidia-current-updates
Follow that with an
sudo apt-get autoremove
Plus, you may want to start afresh on your X configuration
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
If you are still having problems, could you please clarify which instructions you followed to install the nvidia drivers and what you tried so-far to remove them.
Solution 2:
Ok, I found the solution to my problem. After going through all the driver changes that I did, the unity plugin became disabled in Compiz. To fix this, open a terminal, type ccsm to open Compiz, then enable the 'Ubuntu Unity Plugin' and disable all the conflicts and reboot. That seems to have fixed my problems. Turns out it was only loosely a driver problem after all.
