Last week i fixed 2 computers with this problem. Must be some kind of an update.

Log in on a TTY: Ctrl+Alt+F6
- Remove nvidia drivers: sudo apt-get purge nvidia-*
- Make sure ubuntu-desktop is still installed: sudo apt-get install ubuntu-desktop
- Reset some stuff: DISPLAY=:0 gsettings reset org.compiz.core:/org/compiz/profiles/unity/plugins/core/ active-plugins

Reboot.

Perhaps you have to enable opengl and unity. To do so:
- Log in on a TTY: Ctrl+Alt+F6
- Open compiz settings manager: DISPLAY=:0 ccsm&
(If missing: sudo apt-get install ccsm)
- Enable Unity plugin and approve all possible changes

Great, i didn't try to reinstall the nvidia drivers yet.
You might see that dragging windows is a little sluggy, nvidia drivers could solve that.

Im not really fan of proprietary crap. Its the main reason I moved to linux. Im a fan of richard stallman. The only difference as far as I could see of using Nvidia over open source Nouveau driver is when its time to suspend the system. With Nvidia the system doesnt crash.
