I am using Mint 14, 64 bits, cinnamon, on my samsung NP300 laptop. None of the function keys from F1 through F12 are working. Only the following keys are working (that also in a bizarre manner and as if fn key is pressed although I am not touching it.)
F2: brightness gets less by one point from maximum.
F3: brightness reaches maximum.
F5: keypad gets locked
F6: volume mute
Please let me know how I can make them hwork?
