I'm running Mint12 with four monitors. Needless to say, the standard Gnome doesn't work well but it does when using Cairo-Dock instead of the default toolbars and menus.
The problem is that my application menu for cairo-dock is not the same as the default menu for mint and some programs are not showing up. The add-on mint menu doesn't work, probably due to issues with compiz. Compiz does not play nice when using two different cards with xinerama.
How can I load the get it to show the same applications?
