help: kdm killed xd2??

Hi everyone, I installed XD2 last night on SuSE 8.2 from vmware. everything worked just fine and i could log into it last night from gdm. this morning however gdm was gone and the irritating kdm reappeared. it has no mention of Gnome2 or any gnome for that matter and compulsively tries to log me into KDE. Now I don't understand what's happening because red-carpet shows me that all the xd2 files are properly installed. so two questions -- 1. how do i start xd2 now? 2. how do i get rid of kdm and return to gdm? thanks a lot, eugene.
