Affichage saccadé avec l'utilisation d'un dock en usb

Julienh44

Bonjour,

Pour pouvoir bosser sur 2 écrans externes, je possède ce dock : https://i-tec.pro/fr/produkt/u3hdmidvidock-4/
J'ai installé displayLink comme indiqué et une fois l'installation terminée, j'ai bien l'affichage sur mes deux écrans mais ... les deux sont saccadés. Quand je passe ma souris, ce n'est pas fluide comme sur l'écran de mon pc portable.

i-tec m'a répondu qu'il y avait parfois des soucis entre AMD et les drivers DisplayLink.

Est-ce que quelqu'un connait une façon de corriger cela ?

Mon matos :

Asus TUF Gaming 505DT 15'
Carte graph GTX1650 (nvdia)
Ryzen 7
Ubuntu 20.04.1

Merci pour votre aide
Julien

et :

dpkg -l | grep nvidia

dpkg -l | grep -v ^ii
