KDE 3.2, SuSE 9.0, kdm: menu edit?
I have just installed KDE 3.2 for SuSE 9.0. It runs well, but the login manager kdm has changed the previous settings; I'm not actually using KDE that much, I prefer XFCE. In the version of KDE I had before I could change settings for kdm using kcontrol, and there was a list to which I just had to add 'startxfce4' in order to include it in the menu of GUIs. This menu is missing from the editor for kdm settings now, and apparently others are missing, too, for instance the ones where you can set the commands for shutdown etc.
It's not that I am not logged in as root and the items are disabled, they are actually missing. The help file refers to them, but they are not there.
I don't know what's wrong, but I'd be happy if anyone could give me a hint which file to edit by hand to include startxfce4 in the menu. Or alternatively how to disable kdm and use a different manager.
