OpenSUSE 12.2 Step by Step Installation

Hi, I just want to install TDE to my minimal installation of OpenSUSE 12.2. I installed minimal OpenSUSE without X however, I installed minimal X and Trinity but, when I edited the /etc/sysconfig/displaymanager to kdm and windowmanger to startkde it didn't start. Hence, when I looked at /opt/trinity/bin/ inside I saw kdm and startkde. If someone installed TDE to OpenSUSE 12.2, will tell me to steps after installing and configuring minimal OpenSUSE? Sincerely, Eren
