J'ai rencontré quelques problèmes avec mon système Ubuntu (19.04) ces derniers temps. Je pense que c'est lié à la façon dont l'interface graphique est gérée par le noyau 5.0.0.
Mon ordinateur est un Asus ZenBook 13 (acheté il y a quelques mois), mon GPU est intégré (Intel HD Graphics, "Whiskey Lake").
Le principal problème est que je dois souvent (re)démarrer 20 ou 30 fois pour que le système démarre correctement. La plupart du temps, il reste bloqué sur l'écran violet après le menu Grub, et le ventilateur tourne à sa vitesse maximale - la seule façon d'arrêter l'ordinateur est de maintenir le bouton d'alimentation. Cela semble être complètement aléatoire. Je soupçonne fortement un problème de paramètres graphiques. Quand Ubuntu démarre correctement, je peux l'utiliser sans aucun problème. - tout semble répondre parfaitement.
J'ai essayé une réinstallation complète d'Ubuntu, mais le problème a persisté. Pour une raison quelconque, il a encore empiré : maintenant, même une clé USB Live ne se charge pas correctement (j'obtiens juste un écran noir après avoir sélectionné une option [essayer Ubuntu / installer Ubuntu], même en mode graphique sécurisé). Il se peut que j'aie fait des dégâts avec xserver, mais je n'ai aucune idée de la façon de le réinstaller proprement.
J'ai essayé plusieurs solutions potentielles que j'ai trouvées dans d'autres fils de discussion, y compris l'insertion de nomodeset et diverses autres commandes dans les commandes Grub ( acpi=off ...), mais en vain. Parfois, nomodeset me permet d'accéder au mode console - mais, comme je l'ai dit, cela semble être complètement aléatoire.
dmesg -lerr renvoie beaucoup d'erreurs ACPI :

Je ne suis pas du tout un expert. Je fournirai volontiers toutes les données que vous me demanderez.
Quelle pourrait être la cause de ce succès aléatoire du démarrage ?
