After some two hours were passed from the notebook boot time the
backlight controls are got their previous behaviour: I need to press
the F-buttons about 5 or 6 times to get the backlight to up or down.
Something enlarged the "event queue".

Rebooted the notebook: the previour behaviour (one extra press
needed) is restored.
