I've upgraded my laptop from natty to oneiric and I've noticed that when I leave the pc idle (or I manually lock the screen) the back-light is not restored when I move the mouse or press a key, but I must turn it on and increase it using the keyboard button.
Is the same behaviour described in this old bug #199522.
Naturally if I uncheck the option "dim screen to save power" the issue doesn't occur.
