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 Feisty. If you're using Edgy, go here. If you're using Dapper, go here.

Remove Kubuntu
