My laptop is a Gateway NV52L03H, Amd Radeon HD 7520G using the AMD FGLRX drivers. Most of my laptop's Fn (function) keys are working properly and as they should. The only one misbehaving are the brightness keys.

When I change the brightness, it either doesn't work, or changes the brightness a few seconds later. I end up having to keep playing with the brightness keys for it to change. I always receive a notification on screen, even though the brightness usually doesn't change.

How can I fix my brightness keys?
