I was reading an article on Lifehacker and someone made the point that one way to increase battery life was to switch from a heavyweight wm (kde, gnome) to something lighter like fluxbox or fvwm (or maybe even xfce). I was wondering what everyone's opinion on this is. I can't see why kde would use any more battery life than the others--assuming compiz and such aren't on--but I've never really delved much into the world of window managers. The reason I ask is because my new ASUS laptop is getting really poor battery life in linux (suse and kubuntu).
