I originally installed Ubuntu 11.10 on a 64 bit PC, then installed the Xubuntu Desktop. I deleted some applications and eventually the Gnome Desktop. The Xubuntu Applications Menu still shows applications I've deleted. How can I get it to accurately display the Applications/Software on my computer? I also still see the Gnome desktop as an option when I first log in. I'm confused and am very much a newbie to Linux, so please keep it simple. Thanks.
