Des questions:
Avec Optimus activé et la détection du système d’exploitation activée dans le BIOS, je dispose de 2 moniteurs externes connectés via DVI (station d'accueil - carte Nvidia) et du portable LCD (carte Intel) pour fonctionner. J'ai également eu le VGA (carte Intel) sur la station d'accueil, mais ne pouvais pas ne pas l'avoir comme un clone de l'écran LCD de l'ordinateur portable.
Voici ma config xorg avec Xinerama activé:

Dans la section "DeviceIntel" se trouve ma dernière tentative pour obtenir plusieurs moniteurs sur la carte Intel.
Voici un extrait de mon "lspci":
$ lspci |grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: nVidia Corporation Device 1057 (rev a1)
Si vous n'utilisez pas la carte NVidia, vous ne pourrez utiliser que le port VGA unique de votre ordinateur portable. Même si vous vous connectez à une station d'accueil, les ports dvi et d'affichage ne seront disponibles que si vous utilisez la carte NVidia.
