Problème X

[De Leeuw Guy <G.De_Leeuw@eurofer.be>]

Bonjour à tous
Je suis nouveau sur la liste et nouveau en debian.
Je viens de terminer l'installation d'un serveur ia64 Bull novascale
avec debian-sarge-ia64 
Tout fonctionne nickel, excepter X.
J'ai essayer le nouveau kernel 2.6.7, mais sans succès.
La machine est livrée avec RH AS2.1, et la X fonctionne bien.

Je n'ai pas de message d'erreur spécial, X semble tourner correctement
mais j'ai un écran noir
CTRL+Fx ne fonctionne plus.
Uniquement CTRL+ALT+Del fonctionne.
Je suis obligé de me connecter via ssh depuis mon portable pour killer X
dpkg-reconfigure xserver-xfree86 ne modifie pas mon XF86Config-4 est ce
normal ?
Je sais plus ou chercher si qqun à une idée ???

La version de X : 4.3.0.1
Video card :		ATI Match 64 Rage XL 16Mb

Voici mon XF86Config-4
