How do I add shadow to my Gnome Menu Bar?
Some weeks ago I've disabled the shadow of my top panel. And now I want to re-enable the shadow.
I doesn't remember how I disable the shadow, but I already know I haven't done it with Compiz. So the solution with ccsm & window decoration won't help me. I'm really sure I've edited a text file and restarted the panel to drop the shadow.
I've also tried to reset the panel with gconftool-2 --recursive-unset /apps/panel
pkill gnome-panel
but this also doesn't work.
May anyone out there help me?
