bi écran (sans xinérama) avec gdm et drivers nvidia

[Lecouteux Benjamin <assyrium@gmail.com>]

Bonjour, je commence à lutter avec mon serveur X. Ayant une carte nvdia 
gforce classique supportant le bi-écran, je voulais avoir un écran sur 
ma tv et un autre sur mon moniteur. Les deux étant indépendants et 
allumés en même temps. Pour l'instant, je suis arrivé à lancer le 
serveur X sur les deux écrans. Le hic étant que je n'ai qu'une fenêtre 
de login qui se trouve sur mon écran principal. Sur la tv, j'ai un fond 
gris moiré avec le curseur croix quand j'y passe la souris. Lorsque je 
me logue, j'ai deux gnome qui se lancent séparément (mais simultanément) 
sur la tv et l'écran. Hors, j'aimerai avoir une fenêtre de login pour 
chaque écran, et pouvoir lancer le WM que je veux sur chacun. Si une âme 
charitable peut m'éclairer sur le moyen d'y arriver, je lui en serai 
vraiment très reconnaissant.

Merci, Benjamin
