Public bug reported:
I have a Dell XPS M1710 with a GeForce Go 7900 GS and freshly-installed,
fully up-to-date Ubuntu 12.10 amd64. When using Nouveau (the default),
it is impossible to adjust the display brightness. Moving the slider in
Brightness and Lock has no effect on the actual display brightness. The
Fn keys for brightness also have no effect (except to move the slider).
Worse, even though the default slider position is the max, the actual
brightness is the lowest-possible setting, making the machine
effectively unusable with Nouveau.
The proprietary NVIDIA drivers do work (and are active at the time of
reporting this). I am happy to provide more info if needed.
