New linux user here. I goto to system settings brightness and lock and see no setting to adjust brightness. xbacklight -set does nothing. I can adjust keyboard backlight and volume with function keys just fine but brightness keys (f1 - f2) do absolutely nothing. Getting a bit frustrated after spending so much time getting wifi and bluetooth to work. I'm not sure anymore if this OS is really worth the hassle. :confused: Please help.

I've updated drivers, searched and ran multiple solutions and I still can not adjust gamma. Anyone please?
