Ecran Blanc sur sortie TV (ATI 3D rage Pro powered :)

Bonjour,

Synopsis : avec une vielle config je compte me faire un petit media center. J’ai dessus une vieille ATI : ATI Technologies Inc 3D Rage Pro AGP 1X/2X (rev 5c). J’étais originellement sur geexbox qui tourne sans problème mais qui reste assez limité, J’ai alors installé une debian et lorsque je lance mon serveur x je n’ai pas de problème sortie vga mais en sortie TV (composite) j’ai un écran blanc. J’ai tenté de modifier la résolution : sans effet.

Voici mon xorg.conf

et ce que me donne “atitvout tvout vbe”

TV Out is enabled. TV Out subsystem release is 27. Reference frequency is 29.49892 Hz VBE Version: 2.0 VBE OEM Identification: ATI MACH64

Merci de votre aide !

PS : j’ai également un petit problème : la sortie vga est n’est pas activé lors du boot (je suppose que cela viens du fait que j’ai installé la debian sans cette écran)
