[fINTiP <1472897@xxxxxxxxxxxxxxxxxx>]

Public bug reported:

Press Fn + up/down arrow.

Expected to happen: brightness goes up or down; notification in top
right of brightness going up or down.

Actually happened: brightness stays unaffected; notification does appear
and respond correctly, but lies.

Cannot adjust brightness using function key combo. Shows the
notification as if I am adjusting it, but screen stays on max
brightness. Brightness & Lock app doesn't adjust brightness either.

When I switch to proprietary drivers, brightness adjustment does work.
When I turn off the nvidia card and use the intel card, brightness
adjustment works. But with the intel card only I don't have hdmi port
support, so no triple monitor support. And with the proprietary drivers,
I get horrible, horrible bugs, including one that made it impossible to
get into my system until I modified bios settings related to the video
card.
