Now I'm experiencing spontaneous resets of the desktop environment (when logged in and working normally), where the screen will go black, then reset to the login screen.
- The resets appear to be random, though there is a chance it occurs more when using Nautilus.
- The screen goes black instantly, e.g. there is nothing like a disappearing launcher or window borders.
Where can I begin finding the cause?
Info:
- I've recently upgraded from 11.04 to 11.10, then 12.04.
- Using Nvidia drivers "current" (295.40-0ubuntu1)
Are you using Nvidia graphics card? If so, try Unity-2D (in login screen). This might be this problem: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/973096 .
