Similar bug has started to appear here sometime in November 2011. My system is:
Ubuntu 10.04.3
Linux 2.6.32-37-generic
Dell Optiplex 760
Symptoms:
* the first occassions were with a blank screensaver + lock. I have returned
after an hour to find that the screen is not blanked, it was even updating, but
after moving a mouse it went blank and displayed password prompt as it should
* now a new symptom happens frequently (twice or thrice a week at
least), always when I am off the computer for several hours - the X
restarts so when I come back, the GDM greeter is on. I have changed the
screensaver to space images, might be the reason. Happened even soon
after a reboot
