Getting Back to a Pure KDE 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 ubuntu-desktop
or
sudo aptitude remove xubuntu-desktop
to get back to your "pure KDE."

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

Note, this applies only to Ubuntu 7.10 (Gutsy). If you're using Feisty, go here. If you're using Edgy, go here. If you're using Dapper, go here.
