Dual screen avec portable ACER Aspire 1363WLMi / Carte graphique nVidia FX5200
Pour commencer, faire une sauvegarde du fichier XF86Config en XF86Config_single par exemple. Ce fichier devrait se trouver dans /etc/X11 . Le fichier ainsi renommé pourra servir,le cas échéant, à lancer la machine en mono-écran.
Pour information comme l’indique la documentation nVidia, l’affichage étendu sur deux moniteurs est possible. De plus, la sortie VGA externe est l’affichage principal, l’écran du portable est donc le second moniteur.
Voici, pour exemple, mon fichier XF86Config_single :

Comme on peut le constater, le portable a un écran 16/10 (1280x800). Par ailleurs, j’ai été obligé de modifier le ModeLine (Voir la ligne soulignée), car celui par défaut ne permet pas un bon affichage. Il est possible de calculer le ModeLine à cette adresse : http://koala.ilog.fr/cgi-bin/nph-colas-modelines-fr . Il suffit d’indiquer la Fréquence verticale maximum, soit 60 Hz, et la largeur et la hauteur (en pixels) de l’écran. Il ne reste plus qu’à recopier le résultat obtenu dans le fichier à la place des anciennes valeurs.
Le paramétrage d’un affichage sur deux moniteurs se fait dans la section « Device ».
Allons voir ce qui s’y passe :

EndSectionDe plus, vu que la sortie VGA externe est l’affichage principal, on aura pris soin dans la section « Monitor » de mettre les paramètres liés au moniteur externe.

Il va de soi que les valeurs sont à adapter en fonction de votre second moniteur. L’option TwinViewOrientation détermine la position des moniteurs entre eux, ici, le second moniteur se trouve à droite du premier. L’option ConnectedMonitor détermine le type d’écran, CRT pour tube cathodique, DFP pour écran plat et TV pour téléviseur. Toutes les options sont documentées dans le fichier README.txt accessible depuis le site de nVidia suivant la version du driver.
