[GNOME] Résolution écran de connexion [RÉSOLU]

Bonjour !
J'utilise une résolution de 1280x1024. Il arrive mais très rarement que l'écran de connexion s'affiche dans cette résolution. La majorité du temps, l'écran s'affiche en 1024x768.
Dois-je mettre vga=795 dans la ligne du kernel ?

L'écran de connexion (gdm, kdm, ...) est géré par le serveur X et pas par le noyau. Le noyau gère l'affichage uniquement au boot et dans les consoles (Ctrl+Alt+F1-F6 en général).
A mon avis le problème vient de ton xorg.conf (dans /etc/X11).
Peux tu nous le poster ici ?

D'ailleurs je trouve le contenu assez difficile à suivre. C'était beaucoup plus «clean» sous Debian. Je m'y ferai

Il y a pas mal de parametres assez curieux (que je connais pas trop) dans ton xorg.conf, une bonne idée serait de faire un peu le ménage. Si tu veux, il y a une page dédié à l'installation et à la configuration du serveur X :
http://wiki.archlinux.fr/howto:indispen ... figuration
Bon sinon la section importante qui concerne les résolutions utilisées, c'est la section screen. Essais de remplacer ta section screen par ça (en faisant une sauvegarde avant tout) :
Code : Tout sélectionner
Section "Screen"
Identifier "Screen 1"
Device "My Video Card"
Monitor "Écran générique"
DefaultDepth 24
Subsection "Display"
Modes "1280x1024"

Merci pour ton intervention. Cela n'a malheureusement pas changé quoi que ce soit.
Je vais regarder la possibilité de créer un nouveau fichier de configuration qui ressemble à celui utilisé sous Debian.
Je me baserai sur la documentation du wiki concernant la configuration du xorg et ferai des essais avec différentes commandes.
Pour l'instant je suis revenu au fichier original créé lors de l'installation de Archlinux.

Ca pourrais venir également de la section monitor si les valeurs de synchronisation verticale et horizontale ne sont pas bonne. Tu peux tester en commentant les deux lignes qui correspondent.
Bon sinon pour tester, tu peux essayer de lancer le serveur X sans fichier de configuration. Tu fais un mv xorg.conf xorg.conf.old et tu relance gdm. Normalement avec les dernières versions de xorg, il gère assez bien la configuration automatique.

Moi c'est cette partie-là que je trouve curieuse. Pour quoi faire vga ?
Effectivement, tu pourrais refaire un xorg.conf à partir de celui-ci, une fois mieux configuré.
Ceci :

serait mieux ainsi:
Section "DRI"

Avec une ati radeon 9200 SE j'avais
ce xorg.conf.
Dans cet exemple j'ai supprimé le module type1 qui a été rendu obsolète depuis. Pour damage je ne suis pas sûre s'il le fallait.
Pour le reste, je n'ai pas regardé les autres éléments dans le tien.

En faite, il a deux section device pour la carte graphique mais celle avec VGA n'est pas utiliser.
Pour s'en convaincre il suffit de voir le "device" utilisé dans la section screen.

Bon !
Je n'ai pas un moniteur récent. Il aura bientôt 10 ans. C'est un Panasonic E70i. La carte graphique n'est pas des plus performantes, une ATI Radeon All-In-Wonder 7200 (R100).
J'ai donc suivi le conseil de cdemoulins en regénérant un xorg.conf au démarrage. Je me suis retrouvé avec deux fichiers de configuration :
- /etc/X11/xorg.conf.radeon
- /etc/X11/xorg.conf.vesa
J'ai copié la version radeon dans xorg.conf. Je me retrouve avec une multitude de choix de résolution dont 1280x1024 que j'ai activée.
Maintenant j'ai une fenêtre de connexion qui remplit tout l'écran

.
La seule intervention manuelle que j'ai faite au niveau du xorg.conf fut de modifier les paramètres du clavier. Par défaut le générateur m'avait mis un layout cf alors que je dois utiliser ca avec le modèle Microsoft Wireless Multimedia Keyboard 1.0A .

Pourquoi modifier la section DRI ?

La section DRI permet de gérer les accès au "direct rendering infrastructure" c'est à dire l'acceleration 3d de ta carte graphique. La plus part du temps on met 0660 ce qui donne les droits à tout les membres du groupe video.
Normallement, le serveur gère ça tout seul sans avoir besoin de mettre quoi que ce soit dans le xorg.conf (en tout cas chez moi).

Merci pour l'information. Je ne toucherai pas à cette section puisque je n'utilise pas le 3D.
