What could be causing my brightness control to not work on my Intel
graphics card. The acpi values change but no effect takes place.

ehouse@derpy ~ $ sudo sysctl hw.acpi.video.lcd0.brightness=50
hw.acpi.video.lcd0.brightness: 100 -> 50
ehouse@derpy ~ $ sudo sysctl hw.acpi.video.lcd0.active=1
hw.acpi.video.lcd0.active: 0 -> 0

I also have an issue were upon resume by machine reboots. I believe the two
might be related but I am not sure.

I found a couple of other email chains with similar issues but most of them
have been inactive for more then a year.
