Image trouble avec deux cartes graphiques différentes et deux écrans
Bonjour à tous
Voici le topo :
Une carte graphique principale
=> ATI radeon 9250 256 mo sous driver libre, écran CRT en 1280*1024 60 hz (peux pas mettre plus sous ubuntu)
Une carte graphique secondaire
=> G Force 4 MX 440 PCI 64 mo sous les drivers de bas de Ubuntu, écran TFT en 1280*1024 75 hz (peux pas mettre plus non plus)
L'accélération graphique semble marché dans les deux cas.
L'erreur vient du fait que l'image n'est pas nette, les couleurs ne sont pas fixes, mais légèrement changeantes, ce provoque vite des mals de cranes...
Voici mon xorg

Pour moi c'est normal de ne pas pouvoir aller au dela de 60 hz sur le 1er
et 75 sur le deuxieme. 43-60 et 56-75 sont les rafraichissemnts des écrans.
Il faudrait écrire les caratéristiques réelles des écrans en gamme de fréquence Horizontale et Verticale (rafraichissemnt). Il faut voir les caratéristiques constructeurs, ou meme depuis windows.
ensuite on peut écrire des modelines particuliers avec gtf en console, exemple : gtf 1280 1024 85
soit du 1280 x 1024 en 85 hz, que l'on inscrit dans les sections monitor.
