Chargement du pilote NVIDIA intermittent - Erreur: impossible de charger des informations de tout système disponible (Ubuntu 18.10)
Expérimenter avec des pilotes Edge Saignement via Pilotes graphiques-Pilotes PPA
Ordinateur portable Dual-GPU, Ubuntu Budgie avec nvidia-driver-418 gèle l'écran après environ 15 secondes de journalisation, à l'exception de la souris, j'ai donc essayé NVIDIA-410 et 415 et il ne se charge que parfois.
nvidia-settings jette l'erreur ERROR: Unable to load info from any available system
mais charges avec écran partiel

Il apparaît dans /etc/apt/sources.d/ Il y avait un groupe de fichiers référençant le mauvais canal (par canal, je veux dire la version de distribution, si fiable/xenial/cosmique/disco, etc.), donc le nettoyage de ceux qui sont à la main (en les faisant tout le canal correct via sed) Par exemple, Bionic à Cosmic:
Sudo sed -i -- 's/bionic/cosmic/g' /etc/apt/sources.list.d/*
Sudo sed -i -- 's/xenial/cosmic/g' /etc/apt/sources.list.d/*
puis courir
Sudo apt update
Sudo apt upgrade
Sudo apt autoremove
Fondamentalement mettre le système dans un état stable
