Bonjour,
J'aimerais travailler avec trois écrans. Mon activité professionel le justifie , je me sent limité avec deux écrans. J'ai choisi un SLI justement pour le faire.
Je vais donc vous expliquer pourquoi je n'y arrive pas et ou sont les blocages.
tous d'abord quelques informations sur la configuration en place.

Voici les problèmes que je rencontre.
1 Twinview impossible pour deux gpu différent
2 Separate X Screen ( aucun moyen d'envoyer une fenêtre vers un autre écran
3 Xinerama trois écran un bureau, mais des latence de 2 secondes parfois
4 Twinview (2 écran) + separate X screen (1 écran) , dans ce cas là les 2 écrans son considéré comme un seul, donc mauvaise dimension de fenêtre et pas de plein écran
en résumé
Separate X screen : fenêtre bloqué
twinview : impossible
xinerama: très lent
Separate X screen + twinview : Twinview est en mode un écran donc pas du tous pratique.
Pour le moment j'ai choisi xinerama avec ces latences, on perd l'extention composite, donc pas d'effet 3D.
J'ai essayer chacune des solutions avec gnome, kde, xfce, blackbox, fluxbox.

PS:
- J'ai déja essayé d'activer le composite avec xinerama, l'affichage est sans dessus dessous.
- Je connais aussi la solution Xgl-server, mais c'est obselète avec la nouvelle version de Grub.
- J'ai entendu que ati permetait de le faire simplement , mais trop tard, j'ai mes cartes graphiques.
- J'ai déja essayé de forcer les résolutions dans le xorg.conf
J'ai donc 4 problème, une solutions pour un seul de ces problèmes me rendrait très heureux.
Merci à toi noble lecteur pour la lecture de mon problème.
