I've just changed bug description and title, because I've noticed that the problem is independent from "dim screen to save power"
So the problem is very simple: the backlight is not restored when I move the mouse, but I must manually turn on it.
The problem is present in only one of my laptop, precisely an Asus K50IJ; the graphic card is an Intel "Mobile 4 Series Chipset Integrated Graphics Controller [8086:2A42]"
