As I wrote it is working on 13.1 - I have reinstalled old ver. to show
something.

I ran "evtest  /dev/input/by-path/platform-i8042-serio-0-event-kbd" on 13.1 but
that returns nothing even on 13.1.

As I wrote on 13.1 there is problem in upper level (KDE) but in 13.2 - there is
no response on fn (f7/f8 - brightness) keys (using xev).

in 13.1 it works - in 13.2 it doesn't !
