Public bug reported:
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.
