Depending on your login manager (gdm, tdm, etc.) there should be an option to choose a different window manager (Gnome, Trinity, etc.). Look for some sort of option button on the login screen.
That's for a same user usage, after logging out of the present session. I'm not sure what he wants can still be done without the extra session coming from logging in as a different user. Most DMs do support a menu option to switch to a different user without logging out, or trying from a tty with startx. These are after all multi-user operating systems. Officially, openSUSE hasn't supported startx for several years, but for some configurations, startx still works, and for some other distros, it's still and/or better supported.
Running level 3, there was a way, but I don't find my old notes on this. Maybe: one user startx kde -- :1 another user startx kde -- 2:1 I haven't tried that in well over a decade. Far easier with the display manager proper. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)
