Change WIndow Decoration Compiz fusion

Hi at all,

I am running Knoppix 7.2 and i wonder how to change the windowdecoration theme? I already tried gconf-editor, gnome-tweak-tool and of course the standard menu gui.
I can´t change the windowborder colour just the inner look of the windows.

Any help would be awesome!

Kind regards tobi

ok I found out by my self: in gconf-editor just change apps-->metacity-->general-->theme At first I was wrong by trying that with the dconf-editor! the themes are in /usr/share/themes/
