Backlight / Brightness for R580

[zinzolin]

Hello,

Googling nvidia-bl-dkms brought me to the ppa:mactel-support/ppa . Did you install the 0.17.3~natty version? Or did you find something better?

Thanks!

if you are using ubuntu 12.04 than only 0.73 / 0.74 versions are going to work.
Older ones would not with 3.x kernels.
The lastest version of the driver is not avaliabal in any repo including mactelsupport and voria.
