[Toni Leino <tmleino@xxxxxxxxx>]

Hi! Thanks for your advice! The procedure you adviced me was near limits of
my linux and Ubuntu using skills. But I can infrom this problem is solved
currently this way. I suddenly adjusted the audio level from laptop button
to zero. That somehow reseted the brightness function also, and it has been
working okay since then.

Regards, Toni Leino
