Comment puis-je faire fonctionner mon troisième écran (ordinateur portable + deux moniteurs) sur des pilotes w / nvidia?

J'ai un ordinateur portable avec GeForce GTX 560M et j'utilise les pilotes nvidia sur Ubuntu 11.10 pour prendre en charge le second moniteur avec twinview, qui fonctionne bien.

Lorsque j'exécute nvidia-settings et que je connecte mon troisième moniteur (en comptant l'écran d'ordinateur portable), nvidia-settings se fige indéfiniment si je choisis de l'utiliser également en tant que twinview. Si je choisis de l'afficher en tant qu'écran X séparé, d'enregistrer les paramètres et de le redémarrer, ce paramètre n'est jamais appliqué. Voici le fichier Xorg.conf créé par nvidia lors de la sauvegarde:

Je ne suis pas très utile avec X config. Est-ce que je fais quelque chose de mal?

Plus de 2 moniteurs ne sont pas bien supportés par les outils graphiques, selon mon expérience. Il est possible de configurer le troisième moniteur manuellement dans xorg.conf, mais il n'y aura aucun comportement astucieux de plug-and-play. Vous aurez besoin d'une section supplémentaire Device, Screen et Monitor pour activer le troisième moniteur, puis ajoutez l'écran à la section ServerLayout. Voici mon exemple quadrichromique xorg.conf:

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen1" 0 0
    Screen      1  "Screen2" LeftOf "Screen1"
    Screen      2  "Screen3" LeftOf "Screen2"
    Screen      3  "Screen4" LeftOf "Screen3"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
    Option         "Xinerama" "1"

Je ne vois aucun troisième moniteur dans votre fichier xorg.conf, essayez peut-être de l'ajouter? (avant de faire quoi que ce soit, copiez votre fichier xorg.conf

 Sudo cp xorg.conf xorg.conf.old

coller ceci:

 Section "Moniteur" 
 Identifiant "Moniteur2" 
 Nom du vendeur "Inconnu" 
 Nom du modèle "Samsung SyncMaster" 
 HorizSync 30.0 - 81.0 
 VertRefresh 56.0 - 75.0

 # Source HorizSync: edid, VertRefresh source: edid 
 EndSection 
 
 Section "Écran" 
 Identificateur "Écran2" 
 Périphérique "Périphérique0" # ou "Périphérique1" dépend du moniteur connecté 
 Moniteur "Moniteur2" 
 Par défaut Profondeur 24 
 Option "TwinView" "1" 
 Option "TwinViewXineramaInfoOrder" "DFP-0" 
 Option "métamodes" "DFP-0: 1920x1080 + 0 + 0, DFP-2: 1680x1050 + 1920 + 0; DFP-0: 1920x1080 + 0 + 0, DFP-2: NULL "
 Sous-section" Affichage "
 Profondeur 24 
 EndSubSection 
 EndSection

et changez la section de mise en page de votre serveur:

Section "ServerLayout"

Rappelez-vous où se trouve votre fichier xorg.conf, et en cas de problème après le redémarrage, remplacez le fichier modifié par l'ancien. (
