Re: Linux backlight driver
Interesting. Mine is Vaio VPCCW190X. With the same changes I cannot control the brightness. I also tried the nv4x_driver_data. Could you attach the source so that I can try it also?
By the way, I am running Ubuntu, maybe KDE's way of changing brightness is different than Gnome's. Do the brightness control buttons (Fn-F5, Fn-F6) work?
