Public bug reported:
I've opened up LP Bug #1159269 regarding broken xorg.conf on boot but,
even after I got X working properly after running nvidia-xconfig,
brightness wasn't adjustable on my MacBookAir3,1. I had to manually edit
xorg.conf to make brightness adjustable.
In the "Device" section I had to add Option "RegistryDwords"
"EnableBrightnessControl=1":
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce 320M"
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection
I'd expect brightness to work "out of the box" after installing an
nvidia driver.
