After a reboot I got a message instead of the cursor: Something (I can't remember exactly what is was) failed and I should issue " systemctl status sddm.service " to examine the situation. The output showed, that sddm.service was requesting the contents of the /etc/X11/default-display-manager file. In my case the file contained 'lightdm'. I changed this to sddm and now everything is fine.
