- Brightness Control Problem on Sony VAIO with NVIDIA GT-320M
- unable to change brightness settings in sony vaio e series laptop
- Brightness doesn't change on Sony laptop
Now the Problem
I have installed Ubuntu 12.10 (64bit) in this Sony Vaio laptop. After vanilla isntallation the brightness keys are working and I can see the brightness indictaor going up and down but it isn't having any effect on the real brightness of the device.
I have installed 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?
