apport information

** Tags added: apport-collected

** Description changed:

  The lower part of the screen gets scrambled / distorted sometimes. This
  happens very randomly, but not very often. This disruption just
  disappears either after a few seconds or always, when the mouse is moved
  or any key pressed. Everything is immediately back to normal then. The
  last time it occured was today, just a few seconds after login, while
  gnome-terminal and firefox open.
  
  This is a Lenovo G550 Laptop. Lucid 10.04 clean installed in April. The
  problem occures from that time on until now. I tried newer kernel.org
  kernels and the situation does not change. It seems to be a X.org or
  Gnome problem.
  
  I was able to take a photo with my phone a while back:

  part of "lspci":
  00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 09)
  00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09)
  
  I could not find useful information in /sys/kernel/debug/dri/0/
  
  I have Compiz enabled.
