Bonjour,
Après installation de Debian version 10.4 en dual boot sur un PC portable neuf : ACER A315-42-R0WM, le PC boot bien sur Debian mais l'interface graphique (xfce) ne démarre pas (écran noir avec prompt clignotant).
J'ouvre une session en root, et je lance startx et obtiens des messages d’erreur que je n'arrive pas à interpréter.
Voici le contenu du fichier "/var/log/Xorg.0.log" :
