Well, actually you're starting "a session" and the outcome differs related to the used WM and or session script. Something will have an impact here.

(You could try what happens if you actually only start X11 + xterm, ie. "failsafe")

The thing in KDE managing screen setup is krandr.
"kcmshell4 randr" for setup, "krandrtray" in the panel and a script called "krandrstartup" which should be invoked by startkde
If you altered the startkde script to get a different session login, you just might have accidentally dropped it.

If not, you could also check what CTWM does on startup, call "ctwm --replace" from the "regular" session.
