Title:
  xserver crash / system freeze several times a day

Status in “xserver-xorg-video-intel” package in Ubuntu:
  Incomplete

Bug description:
  I have a Dell E6420 Laptop with Ubuntu 12.10 64 bits / Gnome Shell.

  From time to time (several times a day), it get stuck for a few
  seconds, then the system resumes or hangs definitly.

  If it hangs, only the mouse moves, anything else stuck, with CPU
  heating. I have to reboot.

  if it resumes, apport proposes me to report the bug, for 
"apport-gpu-error-intel.py" and says apport has detected a possible GPU hang, 
but i suspect apport itself is buggy and does not its job. 
  WHen the system resumes, from time to time there are problem with the display 
(see picture attached) : characters not correctly painted, or a green banner 
accross the screen.
  i have sevral crash reports in /var/crash directory like 
"xserver-xorg-video-intel.xxxx...crash" that i have to delete manually as 
apport doesnt.
  (I launched the "ubuntu-bug " command to create this report).
