Bonjour, Quand j´était sur Windows, j´utilisais tout le temps mon second écran(un ecran cathodique IBM G54...), mais au fur et à mesure de ma progression dans l´univers GNU/linux, je n´ai jamais réussi à activer Xinerama(pour ceux qui ne savent pas ce que c´est:
http://fr.wikipedia.org/wiki/Xinerama )...
J´ai cependant réessayer sur Archlinux, et ce fut les meilleurs résultat :D, même si je ne suis pas sous ubuntu, le meilleur tutorial trouvé était celui-ci:
http://doc.ubuntu-fr.org/materiel/multi-ecran?s=xinerama#xinerama , j´ai modifier xorg.conf jusqu´à avant la section problème, j´ai rebooter, et je pouvais perdre la souris sur le coté, mais mon second ecran afficher la même chose que mon premier, j´ai rajouter Option "Xinerama" "true" dans ServerLayout, mais ça ne marchait toujours pas, en effet, l´écran restais noir, et je ne pouvais plus lancer gnome-display properties....
Voici mon Xorg.conf:
