Tastatureingabe funktioniert nicht bei Linux-Login?

Ich habe kürzlich mein Papagei-Sicherheits-Betriebssystem von 3.7 auf 3.11 aktualisiert. Das Problem ist, dass ich beim Booten keine Tastatureingaben erkennt. Daher kann ich bei der Anmeldung kein Passwort eingeben und auf das System zugreifen.

Ich kann jedoch vom Wiederherstellungsmodus aus auf das Stammterminal zugreifen.

Der Inhalt von /var/log/Xorg.0.log zeigt an, dass Maus und Tastatur deaktiviert sind.

1. worin besteht das Problem?
2. nach welchen dateien suche ich?
3. Welche Datei muss ich aktualisieren?

Parrot OS basiert auf der Debian-Plattform.

Inhalt von Xorg.0.log
