Une fois de plus, j'ai besoin d'une solution de contournement pour faire face à la carte graphique de mon ordinateur portable qui est presque cassée : Elle ne se réveille pas après la mise en veille !
Le système Ubuntu 14.10 se réveille, mais l'écran reste éteint. Je dois donc appuyer sur le bouton Marche/Arrêt et naviguer à l'aveuglette jusqu'à l'option "Arrêter", pour éviter une mise hors tension brutale.
J'ai déjà désactivé la suspension pour tous mes comptes d'utilisateur en suivant les instructions suivantes cette réponse . Cependant, j'ai maintenant vu trois fois où il a effectivement fait la suspension !
C'était :
- une fois après avoir laissé mon ordinateur portable allumé toute la nuit (je ne me souviens plus du dernier état...)
- une fois après avoir fermé le couvercle, avant de me connecter à un compte utilisateur après le démarrage.
- une fois, alors que l'ordinateur portable n'était pas utilisé pendant une longue période (quelques heures maximum), après l'avoir laissé sur l'écran de verrouillage.
Je pense que d'une manière ou d'une autre, il est toujours permis au système d'utiliser la suspension et qu'il n'y a pas de règle définie pour l'écran de connexion/de verrouillage.
Maintenant, puis-je désactiver la fonctionnalité de suspension là aussi ?
Mise à jour :
J'ai récemment installé lubuntu-desktop
d'essayer LXDE au lieu d'Unity. Maintenant, en mode Lubuntu, je ne peux pas du tout désactiver la mise en veille. Fermer le couvercle fait une suspension qui provoque également la mort de l'écran jusqu'à ce que je redémarre.
La solution doit donc être indépendante du DE utilisé !
