[Bug 357987] Re: [g35] When idle for >20min, segfault at 10 ip b78d34c9 sp bfa8c990 error 4 in libdrm_intel.so

[Geir Ove Myhr]

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  During RANDOM unactivity periods xorg restarts because segfaults of
  intel driver. Sometimes the computer is 4 hours idle and all is fine, no
  errors, sometimes is 20 minutes idle and xservers restarts, and back to
  the login screen, with all the programs (that were open) closed.
  
  kernel: linux-image-2.6.28-11-generic              2.6.28-11.41  (distribution kernel)
  driver: server-xorg-video-intel  2:2.6.3-0ubuntu8  
  xorg version: 1:7.4~5ubuntu18 
  desktop: kde4.2.2
  hardware: motherboard asus p5e-vm with g35 intel integrated graphics
  other: i tried UXA and EXA accel methods, both are causing the same error. I tried to disable
  powerdevil daemon too.
