Title:
Backlight control does not work on Asus Zenbook Pro UX501JW / Nvidia
Geforce GTX 960M
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hello!
Backlight control does not work on Asus Zenbook Pro UX501JW / Nvidia
Geforce GTX 960M.
What I mean by this is that the hotkeys for the backlight does not do
anything. The backlight can be manually set while running on the
integrated intel graphics. (Not with hotkeys).
The nvidia GPU is not detected until Nvidias official drivers are
installed. And after installing that driver (any version) the
backlight can not be changed at all.
I hope this can be solved!
