I just bought a HP pavilion zd8000, and there are severals buttons above the keyboard. The first is the power button, then a volume +/- buttons and a mute button, next to it is a DVD button, and next to that is a button to turn wireless on or off. Is there any way that I can make these buttons work in linux? Maybe not serve the same function but just to get the buttons to work at all. Ideally I just want the volume buttons to work.
