Ich habe einen HDMI-Monitor an mein Ubuntu-Laptop angeschlossen und arbeite normalerweise mit geschlossenem Laptopdeckel.
Aus irgendeinem Grund funktionierte das Setup plötzlich nicht mehr.
Wenn ich jetzt den Deckel schließe, wird der Bildschirm des externen Monitors schwarz, als gäbe es kein Signal. Das System befindet sich jedoch weder im Ruhezustand noch im Standby-Modus, denn wenn ich den Deckel öffne, beginnt alles dort, wo ich aufgehört habe (kein Anmeldebildschirm).

Antwort1
Aus:Problem beim Schließen des Deckels:
Damit Ubuntu nichts tut, wenn der Laptopdeckel geschlossen ist: Öffnen Sie die /etc/systemd/logind.confDatei in einem Texteditor, zum Beispiel als Root.
sudo -H gedit /etc/systemd/logind.conf
Hinzufügen einer ZeileHandleLidSwitch=ignore
Starten Sie den systemd-Daemon mit diesem Befehl neu:
sudo service systemd-logind restart
Wenn das nicht funktioniert, stellen Sie Folgendes ein
IgnoreLid=trueIn/etc/UPower/UPower.conf
