<pre>My display boots black unless I add i915.invert_brightness=1 to my boot
parameters (Fedora 20 beta).

The backlight hotkeys appear to work as I would expect them, except that I
don't press the fn key to activate them, I just press F2 (darker) and F3
(brighter).
I'll submit dmesg and /sys/kernel/debug/dri/0/i915_opregion as soon as I can
reboot.</pre>
