Bonjour,

Descriptions :
Pc : Dell XPS 15
Ubuntu : 20.10
Dock : Dell D6000
Carte graphique : NVIDIA Corporation TU117M [GeForce GTX 1650 Mobile / Max-Q]

J'ai l’écran de mon portable + 1 un écran Acer(branché sur mon D6000) qui fonctionne tres bien, je vourdrais ajouter deux autres ecrans (identique au 1er acer) mais ils se ne sont pas detecté par ubuntu ?
que dois je faire ?
xubu1957 excuse moi mais j'ai regardé les messaages et je ne trouve pas ce qu il faut faire ?
mercix xubu,
c'est ce que j'avais vu , mais le display fonctionne ... a moitié car il me prend deja 1 ecran mais pas d'autres

Le 11/10/2020, Eskis a écritBonjour,
j'ai trouvé une solution alternative. En connectant directement un des écran en HDMI sur le coté de l'ordinateur portable je suis capable d'avoir les 3 écrans en simultanés.
J'ai une dockStation à mon bureau plus récente (D6000) que la WD15, je vais essayer dans la semaine si c'est cela a une quelconque relation.
Mais pour le moment je vais mettre le topic en Résolu.

dans le xandr j'ai 
DP-1-2 disconnected (normal left inverted right x axis y axis)
DP-1-3 disconnected (normal left inverted right x axis y axis)
ca veut dire quoi exactement ?, sinon j'ai remis qq infos
