ctrl+up|down don't change screen brightness any more

hi people,

i had slackware 13.0 on my dell vostro 1320 and it was all good, but since the upgrade to 13.1 i cannot change the screen brightness with ctrl+up and ctrl+down keys...

i'm not even sure how to start with this problem. from what i understand these keys 'call' a bios function...? so that would mean that some kernel module is not being loaded?

or has the desktop environment lost the key mappings and that is causing my trouble?

any ideas would be appreciated. thanks.

I don't have slackware but there are problems with KDE & plasma-powerdevil application. If powerdevil is installed, uninstall it and go from there(find another ap to control battery and screen ...).
Dell (Vostro and some others) seem to be the ones popping up with this issue. I suspect it is Dell proprietary firmware interference with newer KDE &|R powerdevil ...
