ok, c'est noté.
Bon, ben j'ai encore une question...
J'ai réussi à activer le second écran de la Matrox G550, par contre, quand j'essaie de faire la même manipulation avec la radeon, il me dit "no screens found"
Pareil que tout à l'heure... Mon xorg.conf est dans le spoiler.
Juste une précision, si j'enlève ce qui concerne la Matrox, ca fonctionne avec l'ATI uniquement.
