J'ai installé Linux Mint sur Un PowerMac, et j'ai besoin d'un deuxième écran.
Un écran est branché sur la sortie DVI de la carte graphique (RADEON HD5770) et fonctionne très bien. J'ai branché l'autre écran sur l'une des 2 sorties mini-displayport mais l'écran ne détecte pas le signal et m'affiche "Aucun signal".
La présence du deuxième écran est pourtant détectée puisque lorsque je branche le displayport, les espaces de travail sont doublés. Lorsque je déplace la souris hors des limites de l'écran en DVI, (donc sur la zone de l'écran displayport), le curseur de la souris doit se déplacer sur cet écran "virtuel" mais est invisible (écran noir).
Lorsque j'entre dans les paramètres d'affichage, je vois bien les 2 écrans (.ViewSonic 24" sur displayport et HP 23" sur DVI). Je peux faire toutes les modifs possibles, mais L'écran ViewSonic 24" n'affiche rien et reste désespérément en veil.
Le gestionnaire de pilotes me répond "Votre ordinateur ne requiert aucun pilote additionnel".
La commande xrandr donne:
