Bon la session graphique est revenue smile
Pourquoi... telle est la question.
Entre temps, j'ai réinstallé le paquet network-manager mais ça n'a pas produit le résultat escompté dans l'immédiat.
Après j'ai été dans le menu de recovery de linuxmint et j'ai trouvé des options "réparer les paquets cassés" "faire une vérification système" puis poursuite du démarrage. Là encore pas de changement. J'ai pu entre temps voir des messages signalant l'impossibilité d'ouvrir une fenêtre graphique et une indication sur l'erreur dans le fichier /var/log/xorg.0.log que je met ci-dessous.
J'ai fait un reboot et là cà marche...tout marche rien à réinstaller.
Je n'ose plus le redémarrer
