Gnome(prev: KDE4), can't switch user after "lock screen"

Hi
I started using 11.1 a few weeks ago with KDE4 and now I switched to Gnome (KDE still installed).
When a user has locked the screen and another user tries to log in by clicking “switch user”, I get the following error on a popup:

Unable to start a new display
The name org.gnome.DisplayManager was not
provided by any .service files

…and the new user isn’t prompted for login.

Any ideas?

Yep.
I think you use KDM as a display manager and not GDM (Gnome Display
Manager).
It is likely GDM got installed when you installed GNOME but it not used as
the default displaymanager.

You can change this with yast.
Start yast, select System and then /etc/sysconfig-editor
In the sysconfig-editor select Desktop, then Display manager and
DISPLAYMANAGER.
Here you can change the displaymanager you want to use by selecting it in
the dropdown menu.

You can also change this with an text editor as root.
Edit the file displaymanager in /etc/sysconfig.
Look for the line that says “DISPLAYMANAGER=”
Mine reads: DISPLAYMANAGER=“kdm4”
Simply change this to: DISPLAYMANAGER=“gdm” and your done.
