Brightness on MacBook Ubuntu
Ok, after each Nvidia driver upgrade… the brightness section in the Xorg config file gets wiped out, automatically recreated, and we loose brightness control in X11.
Solution :
- sudo mcedit /etc/X11/xorg.conf
- Find the line section « Device » (Nvidia) and ensure last line has got the following
Option "RegistryDwords" "EnableBrightnessControl=1"
