Hallo Wilfried,
Dieses Problem mit dem Xenial-Client habe ich jetzt auch entdeckt, bin mir aber ziemlich sicher, dass das vor knapp einem Jahr, als ich die ersten Laptops mit dem Standard-Cloop eingerichtet habe (zu der Zeit hast du ja deinen Beitrag geschrieben…), noch nicht aufgetreten ist.
Einen möglichen Hinweis habe ich in /var/log/lightdm/seat0-greeter.log
gefunden, so sieht es dort beim Start mit Netz aus:
