I've bought a Samsung R519 and as all others Samsung fn buttons don't work. I've tried to patch the kernel and I can use fn buttons but even if I see notifications of brightness changing nothing happens on the screen, battery works, wifi not, backlight off not, mute yes out of the box, touchpad out of the box. Ask waht kind of info do you need.
