Article sur le multi-head avec une carte nvidia

[KewlCat]

Voici un article interessant pulié sur Phoronix.com : Xinerama v. TwinView.

On y remarque que la solution propriétaire de nvidia est (un peu) plus performante que le générique "Xinerama" implémenté dans Xorg, mais surtout on y trouve des exemples de fichiers de configuration pour ces différents modes !

(Je les copie-colle ici afin d'éviter les déconvenues si l'article venait à disparaitre)
