J'ai une quadroFx 500 avec une sortie DVI, une analogique et un adaptateur DVI->analogique.
J'ai un écran plat 19" et un CRT 17".
Pour l'instant, mon TFT est en DVI et le CRT en analogique.
J'ai les drivers nvidia 6111
Le but : faire du bi-écran avec comme écran principal le TFT

Le pb : le layout2 me démarre bien sur les deux écrans, mais avec le CRT en écran principal. Ça apparemment, c'est normal, c'est le twinview qui marche comme ça 
Il prend la sortie analogique en priorité !
Du coup, j'inverse les branchements grâce à mon adaptateur, je relance X (sans rien changer), et là jai que mon TFT qui s'allume 
C'est pour ça que j'ai un layout 1b dans mon xorg.conf. C'est pour lancer X uniquement sur le CRT. Et ce layout marche pour les deux branchements, D'ailleurs le layout1 aussi, mais pas layout2 
une idée ?
