Forcer résolution d'écran

Bonjour
Je viens d’installer debian sur une tour neuve.
Carte Gigabyte B460M DS3H V2 sans carte graphique dédiée. Processeur intel i5-10400.
J’ai récupéré un écran 16/9 mais dans mes propriétés d’affichage je n’ai que des résolutions 4/3. Je suis branché en HDMI.

quand j’exécute xrandr :

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1600 x 1200, maximum 1600 x 1200
default connected primary 1600x1200+0+0 0mm x 0mm
   1600x1200      0.00* 
   1280x1024      0.00  
   1024x768       0.00  
   800x600        0.00  
   640x480        0.00  

Quand j’exécute xrandr --listmonitors :

xrandr: Failed to get size of gamma for output default
Monitors: 1
 0: +*default 1600/423x1200/317+0+0  default

Donc impossible de forcer la résolution.

Je pense que mon noyau est à jour :

Linux version 4.19.0-16-amd64 (debian-kernel@lists.debian.org) (gcc version 8.3.0 (Debian 8.3.0-6)) #1 SMP Debian 4.19.181-1 (2021-03-19)

J’ai supprimé xserver-xorg-video-intel pour remplacer par firmware-misc-nonfree sans effet.
J’ai modifié pcl1 pour IGFX dans bios sans effet.

Quelqu’un aurai-il une piste ?
Je suis aussi preneur de conseils pour saisir correctement les retours du terminal dans la discussion.
Merci par avance

Es tu certain d’avoir ouvert une session X11 ?

que dit

env | grep SESSION

Bonjour voici le retour
XDG_SESSION_TYPE=x11

A priori ce n’est pas l"ecran HDMI qui est vu mais un ecran par defaut du PC
Dans tous les wiki il est indiqué qu’un écran HDMI s’identifie HDMI

En effet je pense que mon écran n’est pas identifié. Cela peut-il provenir d’un problème de pilote ?

il y a des problemes mentionnés avec Nvidia

j’ai peu de connaissances au niveau du matériel. En partant du topic sur askubuntu j’ai saisi xrandr --listproviders et j’ai eu comme retour :

Providers: number : 0

Faut deja identifier la carte

lspci -nnk | grep -i vga -A2

Bonjour,

Pourrait-on voir le log de X ?

S’agit-il de ça ? (pour Xorg.0)

Sinon je joins le fichier
Xorg.0.log (57,8 Ko)

Question peut-être bête mais as-tu la possibilité de connecter ton écran via le dvi ou le vga? Ces 2 ports sont dispos sur la cm aussi mais à voir s’ils sont présents sur ton écran.

Possible en VGA faut juste que je mette la main sur câble qui va bien.

C’est VESA qui est utilisé pour afficher, ça pourrait expliquer les limites.

Il va peut-être falloir le remettre.
Après un peu de lecture, il semble que c’est i915 qui devrait piloter l’affichage.

Ok merci pour les infos.
J’ai remis xserver-xorg-video-intel et j’ai même fait un petit

sudo dpkg-reconfigure xserver-xorg

avant de rebooter mais j’ai toujours les mêmes erreurs dans Xorg.0.log
Je regarde du côté de VESA

Ce serait un mal inutile, à mon avis.
Le but est que le pilote soit intel et non plus VESA.
Dans l’absolu, le pilote devrait être modesetting mais bon.

Une fois intel remis, ce fichier pourrait résoudre l’affaire :
