Comment avoir sur une seule machine la gestion du double écran alors que l'on n'a pas de double sortie sur sa carte vidéo ?
Avec linux c'est possible
installez votre carte vidéo dans un emplacement PCI libre
au démarrage en console tapez : lspci | grep VGA
vous trouverez les caractéristique de vos cartes vidéo et notamment de la nouvelle installée
ex pour moi :
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03)
01:00.0 VGA compatible controller: Trident Microsystems 3DImage 9750 (rev f3)
j'ai donc le fichier /etc/X11/xconf.org suivant
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf(5) manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.

# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
