- Displaystate not remebered after suspend/resume
+ Displaystate not remebered after suspend/resume (KMS)

** Description changed:

  In my Samsung Q45 with Intel GM965 graphics I encounter the following
  problem when using KMS:
  
  After a suspend/resume cycle the internal LVDS always gets enabled,
  whether it was on before or not.
  
  State before suspend/resume: LVDS: off / VGA: 1600x1200
  State after resuming from suspend: LVDS: 1280x800 / VGA: 1600x1200
  
  "xrandr --query" reports that the LVDS is off and it is not possible to
  turn it off by issuing "xrandr --output LVDS --off"
  
  To finally turn the LVDS off it needs to be "enabled" it first by using 
"xrandr ... --auto". 
  Afterwards it is possible to really turn it off.
+ 
+ Expected behavior:
+ - LVDS stays off after resume when it was off before
+ 
+ Sidenote:
+ If the displays are configured the other way round (VGA off/LVDS on) a 
suspend/resume cycle does not enable the VGA output.
