Ubuntu 18.04 LTS se bloque de manière aléatoire

J'ai récemment installé Ubuntu 18.04 LTS sur mon ordinateur avec Windows 10. Le problème est que, lorsque je surfe sur le Web ou que je fais autre chose, le système se bloque et je dois forcer l'arrêt et le redémarrage. Cela se produit au hasard, prend généralement environ une demi-heure.

Mes spécifications matérielles sont les suivantes: -Intel Core i3-3240 -nVidia GeForce GTX 660 Je ne me souviens pas de la carte mère ni des modèles RAM, mais s'ils sont utiles, je peux essayer de les rechercher. J'ai 8 Go de RAM.

Voici le fichier journal du dernier crash:

Merci beaucoup d'avance. Je vais essayer de fournir toute information supplémentaire nécessaire.

J'ai résolu le problème. Apparemment, ma carte graphique (Nvidia GeForce GTX 660) ne fonctionne pas bien avec les pilotes par défaut, alors j’ai installé les pilotes propriétaires Nvidia et je n’ai pas eu un seul incident depuis. Pour ce faire, j'ai ouvert un terminal et j'ai exécuté les commandes suivantes:

  1. Tout d'abord, j'ai ajouté le référentiel de pilotes Nvidia:

Sudo add-apt-repository ppa: graphics-drivers/ppa

  1. Ensuite, j'ai mis à jour les référentiels et installé le pilote:

Sudo apt update

Sudo apt installer nvidia-387

Le n ° 387 après nvidia est la version du pilote, que vous devez remplacer par la version actuelle du pilote au moment où vous installez vos pilotes. Si vous ne savez pas quelle version utiliser, je suppose que vous pouvez simplement utiliser le 387, qui est peut-être un peu ancien, mais cela fonctionne.

Je suis nouveau sur Ubuntu, alors n'hésitez pas à me dire si j'ai dit quelque chose de mal.
