Lenovo T520 display brightness

[Iwan75]

Hi all,

I am new to Linux O/S and I need some help. After installing the correct driver for my NVIDIA graphics card I found that I can no longer adjust the screen's display brightness at all.

O/S: Kubuntu 12.04 64 bit
Graphics card: NVIDIA QUADRO NVS 4200M
Driver: Linux-x86_64-304.64

thanks.

Run Nvidia X Server Settings. Click on X Server Color Correction. The first item is Brightness.
