Nitpick: kdm is a display manager. A window manager would be KWin.

You can do the same with most other display managers as well.
Simply choose "Switch User" in the menu and then "New session".
I know that this works with sddm.

Maybe some kauth stuff got broken there.

KDM is already dropped from Leap 15.2 and Tumbleweed, so you'll have to switch
away sooner or later.

In the meantime, you can keep the local modification to elarun.xml, but I
recommend
to lock (zypper addlock kdm) the package so that it doesn't get replaced by
accident.
