no Trinity 3.5.13-sru desktop in OpenSUSE 13.1 after install

Hi I got no Trinity 3.5.13-sru desktop in OpenSUSE 13.1 after install. I choose OpenSUSE 13.1 because it is to a Evergeen OpenSUSE with extended support. I followed the instruction in https://wiki.trinitydesktop.org/OpenSUSEInstall even edit file "/etc/sysconfig/displaymanager" and set DISPLAYMANAGER="tdm" And althought I got triinity login manager the desktop that started reveral to Lxde, the other desktop I installed. I tried to edit "/etc/sysconfig/windowmanager" and set WINDOWMANAGER="Twin" or "KDE", "tde" or even WINDOWMANAGER="/opt/trinity/bin/startkdm" it seems to be still hardcoded as described in http://trinity-users.pearsoncomputing.net/?0::4125 Any one have suggestion on making trinity start after login? Thanks in advance
