terminate session logout goes to nowhere

[ClaudiaMS]

Hi,
I have problems within "wm-logout". Pressing the button "logout", executing "loginctl terminate-session etc" command takes me nowhere. The sparky 7 screen with a movable mousepointer is what I get. No chance to log in again or change the user.
Who can help?
I changed to "lxsession-logout", but that can't be the solution"!

Best, CMS
