When I press FN+F4(brightness down) or FN+F5(brightness up) to change the brightness of my screen on my Dell Vostro 5480. It freezes my screen and it seams to "hold" the key and keep reducing the brightness till the maximum or minimum possible and then after a while it stops. Why it happens and how to fix it?

on the following keyboard layout file for your language: (br in my case):
