I have recently installed Ubuntu 12.04 on my Samsung laptop RV509 with Nvidia grahics card but brightness remain unchanged. How can I make the brightness control work?

You can change it using xbacklight

Install it from terminal sudo apt-get install xbacklight

Change brightness by xbacklight -set <level>, where <level> is an integer ranging from 0 to 100 (lowest brightness to highest).

For example, to set medium brightness one would use

xbacklight -set 60
