On my desktop computer, the GNOME main menu on the panel has a different look: it's just one "Ubuntu logo" icon; clicking on it displays the "Applications" menu on top, with "Resources" and "System" being two sub-menus (last two entries).
I actually like this alternate style more than the default one, and would like to have it on my laptop as well. What should I set/alter to have the alternate look on another computer?
(The desktop has always been this way -- I guess it's because it was a Debian machine before, and I installed Ubuntu without reformatting /home.)
You can remove the old menu by right clicking it and clicking 'Remove from Panel'.
