If you installed OpenSuse 11.0 with KDE4 alone and find it either not to your liking or too buggy. Then I have a guide and video you can see to help you add KDE3.
Gnome too if you like, just substitute the KDE choice in the video with GNOME.

I add the Build Service Repo and do update all from the repo filter. Take note too of the need to disable auto-login.

KDE4 is progressing nicely, so this should not be necessary soon.
