Debian 12 Schwarzer Bildschirm bei lightdm

Beitrag von rolfti » 04.12.2024 15:54:57

Hallo, vor 1/2 Tage hat es sich angemeldet, jetzt/bleibt ist der Bildschirm schwarz.
Ein Umschalten mit CTRL+F1 klappt auch nicht. Nutze Mate-Arbeitsumgebung.
Die einzige Möglichkeit auf den Rechner zuzugreifen ist über das LAN - Gott sei Dank, da die Platte verschlüsselt ist.
Restart von lightdm brauchte keine Reaktion.
