Title:
  Brightness is low after resume from suspend, can't be increased

Status in xserver-xorg-video-intel package in Ubuntu:
  Invalid

Bug description:
  In Settings > Brightness & Lock the brightness is set to 100%. Also
  dim is not selected.

  But, after resuming from suspend, the brightness is very low and I
  cannot increase it. Sliding that scaler does nothing and the same with
  the laptops FN-keys, they do nothing.

  Reboot was required to fix the problem. First I tried to restart
  lightdm but could see after stopping it (sudo /etc/init.d/lightdm
  stop) that the terminal on vt1 was way to dim.

  Edit: Last time this happened, I was able to get the brightness back
  by stopping lightdm and starting it again.
