PB affichage sur la TV avec carte ATI radeon

Salut,

j'ai reussi à afficher ubuntu sur ma télé. Pour ça il a fallu que je fasse un "dpkg-reconfigure xserver-xorg" et que je choisisse le driver "vesa" dans xorg.conf.

Hier, j'avais fait exactememnt la même chose sans succès et j'ai compris que le problème venait de l'affichage du démarrage graphique de ubuntu. j'ai donc supprimé dans grub "quiet splash" pour avoir le detail du démarrage en mode texte. Ensuite pas de problème le bureau s'affiche normalement.
Il faut donc très certainement faire un réglage de définition du démarrage graphique d'ubuntu mais je ne sais pas comment faire ça ??

Ensuite j'ai installé l'accélération 3D en utilisant les driver propriétaire d'ATI. Tout s'est bien passé et le resultat est honorable :

12101 frames in 5.0 seconds = 2420.176 FPS
13002 frames in 5.0 seconds = 2600.245 FPS
13003 frames in 5.0 seconds = 2600.476 FPS
13003 frames in 5.0 seconds = 2600.560 FPS

néanmoins, j'ai un petit soucis, j'ai l'impression que l'ecran siffle, c'est léger mais on l'entends. Si je fais une action (ouverture d'un programmeou autre) le sifflement augmente puis diminue??

Pour info voilà mon xorg.conf :

vous remarquerez que vesa est toujours present ???

peut-être que quelqu'un aurait des explications à me donner?

merci d'avance
