Bug Description
This is a nasty bug long before breezy released.
It usually happened after suspension to ram, but I remembered I read somewhere
that if you leave the computer on without doing anything after one hour or two a
similar thing happens. It looks like this:
The mouse cursor suddenly disappears, followed by gnome automatically log out
and then the screen becomes completely black except a busy cursor appears every
10 seconds. Looks like gdm tries to restart but something is seriously wrong.
After many tries, gdm gives up leaving the screen completely black. The keyboard
is responding. Only a hard reboot can solve the problem.
Then I reboot to recovery mode and catch the following error messages in Xorg.0.log:
