System resets to login screen spontaneously
- by Bart van Heukelom
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?
(Note: I've recently upgraded from 11.04 to 11.10, then 12.04.)
