    In new system-installations with XFCE 4.16 will be  generated a
    xfce4-desktop.xml with the Group "<property
    name="monitorDisplayPort-0" type="empty">" after first
    user-login.<br>
    <p><br>
    </p>
    <p>I would create own Distribution Default-Settings for Backdrops.
      But I don't know which Property-Name for the Monitor will be
      created.<br>
      Can I use a WILDCARD in my xfce4-desktop.xml for the Monitor-Name,
      perhaps "monitor*"?</p>
    <p>At this time, I found no solution to Copy a default
      xfce4-desktop.xml to the User-Directory at start to set Default
      Backdrop-Settings.<br>
