Package: src:linux Version: 3.11.5-1 Severity: normal Booting 3.11, the backlight is off, and the brightness control keys do nothing. I did notice that if I hit the power button, the screen manages to come back on during the shutdown process, probably after X exits.
Setting i915.invert_brightness=1 makes it usable, but the brightness is
stuck at max level; the brightness control keys don't change it (they do
generate events, but the brightness is not controlled correctly)..
With 3.10, the backlight was off on boot, but the control keys worked
fine, so it could be turned on.
Nothing relating to i915 in dmesg has changed between 3.10 and 3.11
that I can see.
