Pourtant nicholas est bien super-utilisateur...
tu dois lancer ta commande en root:
su -
puis ton mot de passe root
ensuite tu fais tes commandes
Génial ça marche !!

Mille mercis, ce forum est vraiment au top. 🙂
au passage au lieu de sudo
tu peut faire
# yum -c 'ma commande'

Mais après les avoir supprimés, je vais me retrouver avec un écran noir non?

OK donc il faut que je modifie mon xorg.conf de cette manière? Ou que j'installe livna?
D'après ton xorg.conf, celui-ci a été créé aussi par livna-config-display.
Essaie de le modifier et de re-démarrer puis fais
ls -l /etc/X11/xorg.conf
who -b
pour voir s'il a été modifié par le boot.
Voila le résultat.
Mais ça n'a rien changé...

Salut,
il y a peut-être des informations à récupérer sur lien.

Sinon je te propose de définir le mode 1280x1024 dans xorg.conf.
Teste celui-ci.

Effectivement c'est explicite.
Essaie avec d'autres fréquences. La ligne «ModeLine» est donnée par la commande
gtf  1280  1024  <frq>
avec <frq> la fréquence de rafraichissement.
Essaie 50Hz par exemple.
P.S. : ne pas oublié d'ajouter le nom du mode dans la subsection Display.

Tu peux aussi indiquer les plages de fréquences de ton écran dans la section Monitor. Exemple :
 
HorizSync 27.0 - 115.0
VertRefresh 50.0 - 160.0
Attention ! Il faut utiliser celles de ton écran, où le résultat sera aléatoire.
J'ai ajouté un Modeline et j'ai le xorg.conf suivant.

Je progresse parce que maintenant je peux sélectionner la résolution 1280x1024. Par contre, ça me coupe le haut de l'écran... Bizarre non?
Et puis 1024x768 reste la résolution par défaut.

Et si je passe en 1280x1024 et que je sauvegarde xorg.conf, la partie "Screen" est modifiée comme ça :

Essai en supprimant le twinview dans la section screen :

P. S. : tu peux ajouter d'autres modeline pour avoir un plus vaste choix à tester. Maintenant que les fréquences du moniteur sont définies, peut-être que la validation sera faite.

Et puis 1024x768 reste la résolution par défaut.
Là il faut regarder les messages dans Xorg.0.log.
