[Bug 1034002]


Seems to work for me too.  I'm sure one of Alex's patches helped out
too, so thank you Alex.

I do get this on resume, but that's probably for another bug:
[  117.375124] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting
[  117.375127] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing E442 (len 2585, WS 4, PS 4) @ 0xEB2C
[  117.436913] [drm:radeon_dp_link_train_cr] *ERROR* clock recovery reached max voltage
[  117.436914] [drm:radeon_dp_link_train_cr] *ERROR* clock recovery failed

Bug description:
  I did the kernel smoke test for the quantal kernel on precise.

  I can suspend and resume however when I resume I the screen stays
  black. It looks like the backlight isn't coming on, but it's noteable
  that I don't see anything on my external screen either. I can see
  consoles on my external monitor (over HDMI) and if I disconnect the
  HDMI cable and reconnect it then I am also able to see my Unity
  session on that screen. This issue is present with both the quantal
  kernel and the stock 12.04 one.

  WORKAROUND: Use fglrx.
