Bonjour tout le monde.
Je viens tous juste d'installer Ubuntu 18.04.4 LTS sur mon nouveau pc et à ma grande surprise, mon deuxième écran qui est connecté via un port HDMI (pas de port VGA) est tout noir, enfin la souris s'affiche mais rien de plus.
J'ai changé les résolutions via les paramètres ==> Périphériques ==> Ecrans, mais rien ne se passe.

Alors j'ai vu que nous étions excessivement nombreux à avoir ce problème... Pourtant mon ancien ordinateur dual-bot Windows 10 et aussi Ubuntu 18.04.4 LTS fonctionne parfaitement bien et le deuxième écran s'affiche parfaitement via une connexion HDMI ou VGA.
Du coup, je pense que ça provient du nouveau pc... Est-ce parce que l'écran de mon pc portable se rafraîchit seulement en
120.04*+ 48.01 , et que cette fréquence est trop élevée pour le second écran?
Est-ce du au fait qu'il n'y a qu'une résolution possible pour mon écran principal (celui de mon pc)

1920x1080 120.04*+ 48.01
?
D'autres idées? =) Merci tout le monde. =)
