So, as a number of users seem to be experiencing, I am unable to change brightness on my laptop. Using the Brightness and Lock in settings, the slider moves but brightness does not adjust. The fn keys work for volume but not for brightness. I have updated my drivers and installed all updates, however the brightness is still at maximum.
I have heard that opening
sudo gedit /etc/x11/xorg.conf and entering
Option "RegistryDwords" "EnableBrightnessControl=1" can fix this, however when opening xorg.conf through Terminal I am greeted with a blank document... Not very reassuring.
