J'ai installé une nouvelle Debian sur une machine virtuelle créée dans Hyper-V. J'ai choisi d'installer l'environnement KDE et normalement, il n'y a pas de problème puisque le système se charge toujours directement dans DE. Mais pas dans ce cas.
Dans ce cas, le système démarre sur un écran noir de connexion avec l'entrée du terminal.
Il demande de se connecter et d'entrer le mot de passe, ce qu'il accepte avec succès. Après cela, j'ai toute la liberté du monde pour faire ce que je veux depuis le terminal. Je peux même accéder au bureau KDE si je saisis manuellement startx
commandement.
Je n'ai aucune idée des causes d'un tel comportement. J'ai cherché autour de moi une solution, une telle chose arrive principalement lorsque vous avez plusieurs DE ou aucun, mais KDE est mon seul. Et le système semble être complètement intact, installé à partir d'un ISO officiel.
Lorsque j'ai essayé d'installer un nouvel écran de connexion, j'ai obtenu une erreur de réseau, puis les paramètres du système se sont soudainement plantés avec le journal suivant :
Application: System Settings (systemsettings5), signal: Segmentation fault
