I have a Sony VAIO VPCCW15FG laptop with NVIDIA G210M graphics card. I can't adjust the screen brightness! If I use the Fn shortcuts the brightness notification shows-up and there the brightness changes the level but nothing happens.

I was able to adjust the brightness level in ZorinOS. But nothing happens when I changed the bright level, then brightness level changes radically with each step in the last stages.
