that's fine, and we do need more people looking at this kind of stuff (and
coding). After all, Xfce really has an edge on both Kde and gnome in this
perspective (not only uses it less resources, the average powerconsumption of
xfce4 in any mode -active or not- is far less than that of gnome and kde), and
I'm interested in making it even better by providing a clear point where a
direct huge impact can be made...
I'll unplug the powercord and post some battery consumption numbers in mWh later
tonight, so you can get an idea how much drain we're actually talking about, and
I'll try to find out whether the 200wps in idle can be fixed easily in xfmedia
itself or if it's xine's fault
Brian, I really don't mind that you clearly put it that you don't have time. But
please, if you don't have time, don't diss constructive ideas from other people
right away. You are much better off ignoring (and useful) us completely and
working on something else instead.
Besides that, just for kicks, install powertop and a tickless kernel with
TIMER_STATS, unplug your powercord and give it a try, will you?
