[Résolu] Configurer profondeur des couleurs (?)

shteph

Hello à toutes et tous! 🙂

J'ai un affichage assez mauvais des couleurs sur les images qui apparaissent très sombres. J'ai déjà eu ce problème lors de ma précédente installation (reinstall parce que mort du DD), et je me souviens que pour rectifier ça (sauf erreur de ma part) j'avais modifié la valeur d'un fichier (depth=xxx), mais impossible de retrouver ce fichier (ni son nom)...

Auriez-vous une idée, ou une autre piste, svp?

Merci beaucoup!

Matos et system:

* 2.6.42.12-1.fc15.x86_64
* carte graphique -> G86 [GeForce 8400 GS]

C'est ton fichier xorg.conf /etc/X11/xorg.conf

shteph

Merci pour ta réponse Refuznik, mais j'ai pas de xorg.conf dans /etc/X11/ (ni ailleurs du reste).

J'imagine qu'il faut que j'en crée un...

Saurais-tu ce qu'il faut mettre dedans?

shteph

Je vais essayé ce qui est indiqué ici:

https://fedoraproject.org/wiki/How_to_create_xorg.conf

You can create a basic xorg.conf using the X executable itself. As root run:
Xorg :1 -configure

shteph

Est-ce que quelqu'un peut me dire quoi penser de l'opération dont j'ai parlé ci-dessus, le résultat est-il satisfaisant:

Est-ce que je le garde tel quel, ou est-ce que je dois le modifier (je pense notamment aux mentions des screen 1 à 3)?

Hop!

Personne n'a une idée pour mon problème? :/

shteph

Bon...

J'ai copié tel quel (voir contenu du fichier plus haut) le xorg.conf dans /etc/X11/ et le problème est résolu.

Merci à tous pour votre aide!

korbé

J'ai essayé de faire pareil mais cela n'a pas fonctionné.

Au démarrage Xorg se block et je suis obligé de supprimer xorg.conf.

Mon problème est que j'ai un écran qui gère 10 bits par canaux et non 8, donc après la déclaration du 24 bits (3*8) j'ai rajouté:

	SubSection "Display"
		Viewport   0 0
		Depth     30
	EndSubSection

Mais rien n'y fait. 🙁

Edit: Simple question: Xorg sait-il gérer plus que 24 bits?
