Aujourd'hui, je ne peux pas me connecter à l'interface graphique, mais je peux utiliser la console ( Ctrl + Alt + F1 ) pour se connecter en tant qu'utilisateur ou en tant que root, et je peux me connecter via ssh.
Sous Natty, avant la mise à jour, j'avais configuré Ubuntu pour qu'il se connecte automatiquement en tant qu'utilisateur. Vendredi, l'auto-login fonctionnait avec 12.04. Aujourd'hui, l'écran de connexion s'affiche pour la première fois. On ne me demande pas l'identifiant de l'utilisateur, seulement un mot de passe.
