gnome-settings-daemon prefers backlight devices in the order:
firmware
platform
raw
By default 'nvidiabl' sets itself to 'raw'. Adding this module option allows the
user to configure the type so as to have nvidiabl chosen in preference to other
backlight drivers (such as ACPI platform drivers).
To use it, add the option "type=?" to the module options replacing '?' with one
of the types listed above. E.g:
options nvidiabl type=firmware
or:
sudo modprobe nvidiabl type=firmware
