as I wrote yesterday when I started this thread, there is only kdm-trinity installed.
then you have evtl. missed to also install kcontrol-trinity (which will allow you configure kdm from kontrolcenter)

that's clear, as it is probably already running :) try sudo killall X then from text-console, sudo /opt/trinity/bin/kdm.
