Hi damdim,

I've got the same laptop Sony VPCCW1

I followed the steps you mentioned exactly, but when I try

Code:

echo 50 | sudo tee -a /sys/class/backlight/nvidia_backlight/brightness

as you mentioned, the brightness does not change.

I've even tried removing and recompiling the nvidia_bl module, but it still has no effect.

Please help!
