using kernel 2.6.31 + todays drm-intel patches from Jesse Barnes' tree
there seems to be a problem related to the backlight of the LVDS display:
(using a laptop with a GM965 GPU)
When closing the lid of my laptop, the xrandr status switches from
LVDS1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 304mm x 190mm
1440x900 60.1*+ 59.9
LVDS1 disconnected 1440x900+0+0 (normal left inverted right x axis y axis) 304mm x 190mm
But when peeking under the closed lid I notice that the display stays active!
Only after executing "xrandr --output LVDS1 --off" it will finally get switched off.
I observe this when running X as well as using a console.
