What a wonderfull feeling.......yesterday by accident i moved the volume scroll on my system.... It is a multimedia keyboard .... however i never expected that linux has installed the appropriate drivers for it .The above screen shot is that of the volume and the bottom is that of mute. Besides the play,next,previous,stop all work..By the way i am using kubuntu :) . Go linux !!! Go!!!! You rock
