Description:
After installing the current nVidia driver on my MacBook Pro 5.5, changing the screen brightness doesn't work.

Additional info:
graphics card: nVidia Corporation C79 [GeForce 9400M]
packages: extra/nvidia 280.13-1

Steps to reproduce:
Try to adjust screen brightness in any way possible. Indicators might tell you that it happens, but the screen brightness level doesn't change.

Fix:
Add

Option "RegistryDwords" "EnableBrightnessControl=1"

To /etc/X11/xorg.conf.d/20-nvidia.conf in the "Device" section as shown in attachment.

How is this not worth implementing? It's clearly a bug that it _doesn't_ work, and this is a fix that makes it work. I wouldn't mind a bitter - integrated - fix, this is just how I fixed it locally. But this is clearly a bug worth fixing.

if is a bug then it should reported to nvidia instead of using workarounds.

Right, I was just told, on #archlinux on freenode, that I should report it here. Will look in to reporting it nvidia.
