Comment 2 for bug 175986

Not sure which plugins are actually enabled - I've just switched on the "Normal" checkbox on the "Visual Effects" page and was happy that windows have shadows now :-)

But I have disabled this behavior now in ccsm: enter "switch" as Filter, select the first icon (in section "Desktop"), switch to "Actions" tab, in the list select the second entry ("Switching on the desktop"), and set all "Button5" and "Button4" texts to "None".

Apparently the gconf options that are set with ccsm for this are not contained in any gconf schema, so they don't appear in gconf-editor by default either :-/
