J'ai fait une installation propre d'Ubuntu 20.04 et il ne reconnaît pas mon deuxième moniteur.
J'ai déjà exécuté les commandes suivantes (je crois que seules celles-ci fonctionnaient dans la version 19.10) :
sudo apt update && sudo apt upgrade -y
sudo ubuntu-drivers autoinstall
le pilote vidéo que j'utilise est nvidia-driver-440
