== Faire fonctionner la carte intégrée pour l'écran

Voir [[https://linuxfr.org/forums/linux-general/posts/utiliser-la-carte-graphique-nvidia-et-la-carte-intel-integree|LinuxFr - Utiliser la carte graphique NVIDIA et la carte INTEL intégrée]]

PS :
Xorg est obligé de créer un "Screen" par carte graphique, et qu'un Screen n'est pas un écran physique

#   If the X server does not automatically detect your VGA device,
#   you can manually set it here.
#   To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data
#   as you see in the commented example.
#   This Setting may be needed in some platforms with more than one
#   nvidia card, which may confuse the proprietary driver (e.g.,
#   trying to take ownership of the wrong device). Also needed on Ubuntu 13.04.
#   BusID "PCI:01:00:0"

#   Setting ProbeAllGpus to false prevents the new proprietary driver
#   instance spawned to try to control the integrated graphics card,
#   which is already being managed outside bumblebee.
#   This option doesn't hurt and it is required on platforms running
#   more than one nvidia graphics card with the proprietary driver.
#   (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT).
#   If this option is not set, the new Xorg may blacken the screen and
#   render it unusable (unless you have some way to run killall Xorg).
