I was trying to install the proprietary nvidia drivers for my optimus laptop. This resulted in my GUI disappearing, I can only see my desktop background (can still open terminal and right-click the desktop to get into options). I have followed lots of tutorials that don't result in any change. How can I switch back to the Nouveau drivers that are already installed? I have an nvidia 660m with optimus

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.

That didn't work. Neither nvidia-current nor nvidia-current-updates is installed, and apt-get autoremove found no packages to remove. sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup failed with "mv: cannot stat ‘/etc/X11/xorg.conf’: No such file or directory" as the error. I was installing bumblebee 3.1. The first set of directions was "sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update sudo apt-get install bumblebee bumblebee-nvidia", which didn't break anything but also did not get the graphics card working. It then had me remove my nvidia drivers, which broke the GUI– EvilBlobMar 6, 2013 at 3:49

The webpage with these instructions seems to have been removed, possibly do to this problem– EvilBlobMar 6, 2013 at 3:51

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.– EvilBlobMar 6, 2013 at 4:11

Sounds good. You can add that as an answer (it's possible to answer your own question and get reputation for it) if you like. Mar 6, 2013 at 13:38

Turns out it was only loosely a driver problem after all.
