Opensuse won't change desktops

Hi all,

New user and first post here. Hopefully this is the right place for my question?

I installed Opensuse 13.1 yesterday to try something new from Ubuntu. I was playing around last night changing to the different desktops to see what they all look like and offer in way of changes. I was doing it by way of YAST> /etc/sysconfig> Desktop> Window manager> Default_WM. Everything was okay and I went to sleep after playing around getting familiar all day.

Woke up this morning and decided which interface I wanted to use for now, XFCE, but now the desktop won't change. If I set XFCE, hit CTRL-ALT-BACKSPACE (twice) nothing happens? It's still on KDE4. I tried rebooting back into it, tried shutting off the laptop awhile to let the memory dump, nothing works. It just stays "stuck" on KDE4. What am I missing? I also tried to change to all of the other interfaces too, nada.

TIA,
Mark

EDIT: FWIW, I downloaded Opensuse ISO and burned it to DVD for the install, did any obligatory updates after install and everything is running fine, except for this issue?
