The following line can be added to the "Devices" section of xorg.conf to enable brightness control while using the nVidia binary driver: Option "RegistryDwords" "EnableBrightnessControl=1"   This results in a high-pitched noise emanating from the display, which does not occur when the brightness is changed via the virtual terminal.
