messed up login (KDE 3.1 on Suse 8.1)

Hello together I just moved to Kde 3.1 on a new installed suse 8.1. I was playing around with the settings of the Loginmanager (put a clock, my user should be preselected etc.) Now what i got is a list of many users (dialup,.....) and of the possible sessions KDE is gone :( (in the kcontrolcenter it says that it should be there) When login now i just get a xterm from where I can start Kde, and then everything works fine. I putted all settings back to defaults, but nothing :( Anyone an idea how to get this thing back. I would have no problem with reinstalling the rpm containing the loginmanager, etc. Thanks for your help Andi
