#387 - 20141221 - Fix laptop backlight hotkeys with Intel Nvidia hybrid graphics using Bumblebee

Fix the backlight Fn hot keys on your Asus (and others) laptop with Intel / Nvidia hybrid graphics running Xubuntu Linux 14.04 or 14.10 with Bumblebee. Also valid for Edubuntu, Lubuntu and Ubuntu Studio, possibly also Ubuntu and Kubuntu. Not only will you fix the backlight but you'll get the full potential from the Nvidia discrete graphics adapter for Linux gaming too!
