Title:
  Displays won't come out of suspend.

Status in “libdrm” package in Ubuntu:
  New

Bug description:
  Radeon board has one HDMI and one VGA attached monitors. If the
  monitors go into suspended mode you can't get them out. Power cycling
  the monitors is the only way to recover.

  Everything is working ok, in the main PC. It just looks like the
  radeon driver is not telling the monitors to wake up when escape/mouse
  is pressed to get to the login screen needed to exit suspend.
