Je viens vers vous car il me semble que j'ai un problème de drivers sur mon nouveau pc après avoir installé la version 20 Ulyana de Linux Mint.
En effet je n'arrive pas a changer la luminosité de mon écran, ni l'echelle d'affichage, ni meme la résolution, a chaque fois j'ai une erreur de ce type :
Code: Select all
la taille virtuelle demandé n'est pas adapté a la taille disponible : demande=(1536,864), minimum=(1920,1080), maximum=(1920,1080)
Je vous met quelque résultats de commandes en esperant que ca puisse aider.
