Salut à tous,
je suis sous Gentoo, et j'ai Xorg 7.2 (1.3).
J'aimerai utiliser le dual head de ma carte graphique (ATI Radeon) avec le pilote libre (pour beryl et le DRI).
Je voudrai avoir un "BigDesktop".
Donc, voici ma partie Device de xorg.conf
Citation :

Identifier "card0"
Driver "radeon"
Option "AGPMode" "4"
# le DRI
Option "AccelMethod" "XAA"

# Maintenant, MergeFB
Option "MergedFB" "true" #Enable MergedFB function
Option "MonitorLayout" "CRT, CRT" # Use LCD and CRT even if you have 2 LCD's or CRT's
Option "CRT2Hsync" "30-70" #Horizontal Sync of the Monitor (check your monitor's manual for correct values)
Option "CRT2VRefresh" "85" #Vertical Refresh rate of the Monitor (check your monitor's manual for correct values)
Option "OverlayOnCRTC2" "true"
Option "CRT2Position" "LeftOf" #Physical location of your secondary monitor in relationship to your primary monitor.
Option "MetaModes" "1024x768-1024-768" #Monitor Resolutions for Primary-Secondary monitors
Option "MergedXineramaCRT2IsScreen0" "false"
BusID "PCI:1:0:0"

Donc, voici ce qu'il se passe, ça démmare, et j'ai un beau clone de mon premier écran sur le second, totalement inintéressant.
Donc, j'ai recherché dans le log de Xorg, et je suis tombé sur ça :

Voilà, j'ai cherché, et là je ne sais plus quoi faire, j'ai tenté des tas de truc mais ça na jamais marché.
Si quelqu'un peut m'aider, je le remercie d'avance.
