[Résolu] Résolution 1680x1050 avec controleur graphique intel

Bonjour,

Je viens d'acquérir un écran ViewSonic VX2025wm 20' dont la résolution max est de 1680x1050.

Impossible de me mettre à cette résolution. J'ai essayé tous les conseils de cette doc : http://doc.ubuntu-fr.org/materiel/fix_problemes_resolution

... mais sans résultats.

Pour infos ma config et mon xorg :

- Ubuntu Feisty Fawn
- Carte graphique : Intel Corporates 82865G Integrated Graphics Controller

# /etc/X11/xorg.conf (xorg X Window System server configuration file)

#   sudo dpkg-reconfigure -phigh xserver-xorg

Re : [Résolu] Résolution 1680x1050 avec controleur graphique intel

J'ai résolue le problème en installant les packages suivant :

(je rappel que ma carte graphique est basée sur un pilote Intel 82865g)

- xserver-xorg-video-intel
- 915resolution

Me suis aussi inspiré du lien :
http://www.ubuntu-es.org/index.php?q=node/47127

Ensuite un :
sudo dpkg-reconfigure xserver-xorg

Et le pilote "intel" est apparue dans la liste, je l'ai sélectionné, puis plus loin j'ai choisie ma résolution 1680x1050.

un : Ctrl+Alt+Ret.Arr

puis en allant dans le menu : Système > Préférences > Résolution de l'écran
... j'ai retrouvé dans le menu déroulant la résolution "1680x1050"

et hop ça roule.

[Résolue]
