The ubuntu seems to be always on the max brightness.
I cannot change the brightness. Really strange.
What I have tried:
1 Install the latest Nvidia Driver does not work
2 change x
sudo gedit /etc/X11/xorg.conf
Section "Device" Identifier "Default Device" Driver "nvidia" Option "NoLogo" "True" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection
This would make the fn+ key successfully change the value of
However the brightness will still stay the maximum.
