Title:
  nouveau: dark screen after suspend/resume

Status in Accelerated Xorg driver for nVidia cards:
  Incomplete
Status in “xserver-xorg-video-nouveau” package in Ubuntu:
  Invalid

Bug description:
  Nouveau works fine with brightness controls working fine after initial
  boot, but I do S3 suspend, and then resume via power button, and
  brightness controls don't work at all, and backlight is on, but set at
  extremely low level.

  hardware is Quadro 770M on HP 8530w laptop

  /sys/.../brightness control does nothing when in this state,
  suspend resume cycles after this first cycle all have the same problem.

  I'll test if a full hibernate has the issue or not after this and
  report back.
