<span class="quote">> It is not a bug in -intel or i915.ko, but in the acpi driver for your
> backlight.</span >
The backlight works fine when you hit the sysfs node directly, but the
backlight returned through XRandR (and xbacklight) always returns 100%. It's
possible that the driver always exposes the backlight interface, and returns
100 when it can't actually access the sysfs node for whatever reason as per the
commit below.
