Now the Problem

I have installed Ubuntu 12.10 (64bit) in this Sony Vaio laptop. After vanilla isntallation the brightness keys are workinga nd I can see the brightness indictaor going up and down buit its isn't having any effect on the real brightness of the device.

I have installer additional drivers too but that didn't solve the problem. I can't seem to be able to change the brightness.

Anyone knows how I can fix this?
