Bonjour

des que j'ai une maj de kernel et donc des kmod, ma conf video Xorg.conf est perdu, et je n'arrive plus à lancer mon serveur X.

Je suis sur un portable Lenovo Ideapad, avec une carte Nvidia interne. ma FC17 est en 64Bit.

merci de me donner votre fichier Xorg.conf
Au lieu de te donner un fichier qui correspondrait pas à ton matos, as tu installé le akmod ?
les kmods sont des modules précompilés pour un kernel donné, donc à chaque changement de kernel, il faut changer le kmod, parfois, il y a un petit décalage entre la sortie du nouveau kernel et celle du kmod correspondant, d'ou les problèmes d'écran noir et autres "joyeusetées" du genre.
par contre le module akmod, permet lui de générer au démarrage de la machine le kmod correspondant au kernel qui se lance, d'ou l'absence de problème.
il faut donc preferer le akmod au kmod, si on a pas la patience d'attendre la sortie du kmod avant d'upgrader son kernel.
ok merci pour cette info

mais ca ne fonctionne tjr pas

J'ajouterai juste une petite chose à ce qu'a dit modmol, il faut installer les outils de développement, si non les kernels modules ne pourront pas être recompilés pour le nouveau noyau. Si ce n'est pas fait:
yum groupinstall "Outils de développement"
bien sur pour que le système soit capable de construire les modules il faut avoir installé kernel-devel et peut-être même kernel-headers, bien que je ne sois pas affirmatif pour ce dernier.

malebolgia : peux tu nous faire parvenir le résultat de la commande suivante :
rpm -qa | grep nvidia
j'ai installé les packages de dev avec yum groupinstall "Outils de développement" -y --nogpgcheck
