Installed XFree 4.0.3, then lost KDM

I've just installed XFree 4.0.3. The installation seemed to go correctly, but when I rebooted I got a console login prompt rather than the KDM login screen. Twice I went into Yast1 and selected graphical login/KDM, but it had no effect even after rebooting. Now the only way I can get into X is by logging in in console mode and doing a startx. I observed that kdm wasn't on root's path, so I kludged a link to kdm from /usr/X11R6/bin to /opt/kde2/bin/kdm. That didn't help either (and seemed vulnerable to later updates). How can I get KDM back? Paul Abrahams
