openSUSE 12.2 lockup starting DM after exiting startx

I've a bunch of systems with OS 12.2, but only one or two with TDE. On the one currently wired up, which uses sysvinit-init instead of systemd init, I normally boot to runlevel 3, same as on most of my systems. If as normal user I do startx -- :1, exit TDE, and then switch to runlevel 5, the system quickly locks up completely, and puts the display in sleep mode. IIRC, this doesn't happen on KDE3 or KDE4 systems. :-( Where in the world does one begin to try to figure out the cause?
