I started with Ubuntu Karmic, and wanted to try KDE. So I installed
kubuntu-desktop. Then I wanted to see how XFCE progressed, so I installed
xfce4. I now have Kubuntu with an XFCE splash and login.
How do I (safely) purge XFCE and just have the Kubuntu splash / login screen, or am I stuck with frank-en-buntu?
