Getting Back to a Pure Gnome on Ubuntu

If you used aptitude to install other desktop environments, you will not need this tutorial, as you can just type

sudo aptitude remove kubuntu-desktop

sudo aptitude remove xubuntu-desktop

to get back to your "pure Gnome."

If you didn't have as much foresight and chose instead to install KDE or XFCE through Synaptic or apt-get, this is how to remove those desktop environments from your Gnome.

Note, this applies only to Ubuntu Edgy. If you're using Dapper, go here.

Remove Kubuntu
