Title:
  Brightness set to maximum after DPMS standby

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  After configuring screen energy saving in KDE, I noticed that after
  DPMS standby, my screen brightness is set to maximum. This is
  confirmed by `cat /sys/class/backlight/intel_backlight/brightness`.
  The problem can be easily reproduce by switching to standby manually
  using  `xset dpms force standby`.

  Steps to reproduce:
  1) echo "300" | sudo tee  /sys/class/backlight/intel_backlight/brightness
  2) cat /sys/class/backlight/intel_backlight/brightness 
  This will report: 300
  3) xset dpms force standby
  4) Move mouse/press key
  5) cat /sys/class/backlight/intel_backlight/brightness
  This will report 937
