Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

after regular updates/upgrades my gnome-shell stopped working and got into fallback mode. I have tested installing nvidia drivers (i have an nvidia gfx), removing them, blacklisting nouveau and other basic stuff i have found here on the question-board but none seem to work so far. With a gnome shell --replace i can get the shell running. But its always buggy/choppy and unusable. Even with the windowskey / superkey the dashboard just flickers on/off/on/off and parts of the ui just vanishes and reappers all the time. Like i said... unusable.

I'm using:

  • GNOME Shell 3.4.1
  • Ubuntu 12.04

Any ideas i can tryout? Thanks for the help in advance.

Edit: gnome-shell only works with nouveau. nvidia does give me an error when i try --replace

Errormessage: Xlib:  extension "GLX" missing on display ":0".

Seems like my nvidia drivers are not loading. In jockey-gtk its displaying: activated but not in use

Solution: Restart & press shift. Start in rescue mode. Start failsafeX to unlock filesystem & cancel back to terminal. Open root terminal

cd /tmp/
wget download.nvidia.com/XFree86/Linux-x86/285.05.09/NVIDIA-Linux-x86-285.05.09.run
chmod +x NVIDIA-Linux-x86-285.05.09.run
sudo ./NVIDIA-Linux-x86-285.05.09.run
  • You can also get the latest drivers as @dibs suggested. For me on my old system these drivers ran just fine. Make sure to blacklist nouveau, tho.

Try rolling your nvidia driver back to 295.40, this just fixed a few issues like this with my 12.04 x64.
