Medion E6214: Again Problems with the brightness (or this time FN-Keys)

Hello everybody,

I have a problem with the brightness control of my screen from my Medion Laptop again. This time are the Fn-Keys the problem. On openSUSE 12.2 the keys worked great after I got a solution from the user pistazienfresser with the kernel command “acpi_backlight=vendor”. Since the update from 12.2 to 12.3 with a clean install this kernel command works partially for me. I am now able to change the brightness of the screen with the slider on the battery Application but not with the FN-Keys. So I tried to find solutions and I tested the Shortcuts with the programm “xev” on the console and didn’t get a feedback about this keys.
On openSUSE 11.4 i got this output:

How is it possible to get this working again in 12.3?

If it helps, this was my last topic a year ago: http://forums.opensuse.org/english/get-technical-help-here/laptop/472227-medion-e6214-md98330-not-able-change-brightness-screen.html

I hope, my terrible English is readable :wink:
