Title:
  [precise] bad interplay between X driver and 3.2.0 kernel

Status in “grub2” package in Ubuntu:
  Invalid
Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Updated 2012/04/05:

  On 11.10 and earlier, if I used a default /etc/default/grub file, the
  kernel would boot fine and X would run fine.

  After upgrading to 12.04 today, I found that while lightdm would come
  up, after I logged into the desktop X was horribly broken with
  flashing colors and the like. This was my only clue in kern.log:

  Feb  1 14:12:58 harry kernel: [   33.626782] [drm:drm_mode_getfb]
  *ERROR* invalid framebuffer id

  I verified that booting into the 11.10 kernel on precise works as
  expected: I can always login to the desktop whether I access the grub
  menu or not.

  Occasionally I am able to login to the desktop (1 out of 7 times).
  Warm vs cold reboots does not seem to matter. Waiting to login to
  lightdm seems to increase my chances of a successful login to a
  functionaly desktop.
