My second monitor was not working properly (it seemed to refresh only the parts around my cursor for some reason), so I tried to install nvidia-current to test with new drivers.

This had the following effects:

  • When booting Unity, it only shows the wallpaper. When using ccsm and trying to reenable Unity, it resets instantaneously because I am unable to enable OpenGL.

  • The second monitor doesn't even show up as a choice in arandr or gnome-control-center -> Display

So how do I fix this? I've already tried purging nvidia-current, but I'm not really sure what part of the installation was botched. Before rebooting and experiencing the faults I also ran nvidia-xconfig, that generated /etc/X11/xorg.conf. I have since deleted this file since my resolution was locked to 640x480.

I would like to be able to use my second monitor, but I'll settle for being able to run Unity at all!

Let me know if you'd like me to post any logs from somewhere.

mg@kerouac nux $ ./unity_support_test -p
Xlib:  extension "GLX" missing on display ":0".
Error: GLX is not available on the system
