OK, I seem to be reading the wrong places, or just missing something obvious...

My HD Install brings up kdm as the default login manager. One of the options available is "Session Type", but I can't seem to figure out where that menu gets it's values so I can change them. I'm trying to optomize for the older machines I have at home so I'd like to make sure the kids and other family members default to XFCE (or maybe XFCE4 - any thoughts?) with IceWM as the other option. So I'd like to drop KDE and such from the menu.

I've seen the postings about /etc/init.d/knoppix-autoconfig, but since the list there is different than the list that shows up, I'm guessing that's not the right location to change.

Thanks in advance!
