Subject: [v3.20] ACPI backlight problem

When I press backlight keys then normally OSD is shown and
backlight follows immediately the keystrokes step by step.

Now in v3.20 it behaves different:
When I press backlight keys at first nothing happens. If I watch a
video it is being stopped.
After some seconds OSD is shown, backlight changes - in one step - to
the new level and video continues.

Thanks, Jörg

That's how it works in 3.19, right?
