Hallo,
habe schon vor Tagen geantwortet, aber erst jetzt bemerkt, dass mein Posting nicht veröffentlicht wurde (vermutlich vergessen, nach der Vorschau den entsprechenden Button anzuklicken).
Leider erkenne ich nicht, ob in den Dateien etwas Verwertbares zu finden ist. Deshalb stelle ich die Texte hier ein. Da die komprimierten Dateien (*.gz) offenbar nur Historie betreffen, lasse ich sie weg und kopiere nur den Inhalt von seat0-greeter.log.1.gz, weil die aktuelle leer ist. Hier die Ausgaben:
