Hi,
     I installed Trinity in my openSuSE 12.2 on X86_64, using the instructions on your website. 

     With DISPLAYMANAGER="/opt/trinity/bin/kdm" in /etc/sysconfig/displaymanager and DEFAULT_WM="kdm" in /etc/sysconfig/windowmanager, booting the system displays the Trinity login prompt, but when I enter my username and password, the display just blinks and refreshes the password field. 

     I have looked in /var/log/messages, /var/log/warn, /var/log/Xorg.0.log, xdm.errors and kdm.log, but the only suspicious items I see are in kdm.log:

QWidget::setMinimumSize: The smallest allowed size is (0,0)
QWidget::setMaximumSize: (unnamed/QDialog) Negative sizes (-1,-1) are not possible
Feb  8 13:39:24 kdm_greet[28323] error: Can't open default user face
QImage::convertDepth: Image is a null image
QImage::smoothScale: Image is a null image

     Perhaps one or more of these is causing the issue?  Any suggestions on how to proceed are welcome.
