Je ne sais pas comment résoudre ce problème : je devine qu'il y a un problème de boot mais comment changer cela ? Cela marchait bien avant la MAJ.
Merci d'avance.

Bonjour,

Vue la description du problème, je suspecte un problème de pilote de carte vidéo plus qu'un boot cassé.

Est-ce que tu vois apparaître grub au démarrage ? Si oui, est-ce démarrer "recovery mode" donne quelque chose (dans grub, tu peux démarrer en mode sans échec via le sous menu "Options avancées" ?

Est-ce qu'il se passe quelque chose si tu fais la combinaison de touche ctrl alt f1 ou ctrl alt f2 ? Si oui, cela signifie que le problème vient du pilote de la carte vidéo, et non de ton installation linux. Dans ce cas, peux-tu t'indentifier sur la console qui s'affiche (tape ton login, entrée, puis ton mot de passe en aveugle, puis entrée). Tu devrais alors voir une invite de commande apparaître. Derrière, lance les commandes suivantes, et indique-nous leur résultat (tu peux prendre une photo et la joindre à ton prochain message) 

lspci | grep -i VGA
lspci | grep -i 3D
grep EE /var/log/Xorg.0.log


Bonne chance
