Title:
  Kernel mode switching causes screen flicker every few minutes on Intel

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I have this Intel chip in my laptop:

  VGA compatible controller [0300]: Intel Corporation Mobile 4 Series
  Chipset Integrated Graphics Controller [8086:2a42] (rev 07)

  and when I switched to Lucid beta I started seeing my screen flicker
  occasionally, about every few minutes on average (I haven't noticed
  anything that triggers flickering, it just seems random).

  I have used the laptop for many hours with KMS disabled
  (i915.modeset=0), and there was no sign of flickering.

  Bug 402982 seems like it might be closely related, but that describes almost continuous flickering, not every few minutes.
