Re: Passer en 1920x1080 une machine démarrant avec i915.modeset=0 ?



Faut écrire :
$ xrandr -s 1920x1080 # Notez le 'x' et pas le '*'

Est-il possible de "lancer manuellement" la fonction KMS une fois que
l'on a démarré avec i915.modesetting=0 ?

Bonjour,

Il faut être connecté avec le compte qui fait tourner la session Xorg
(sinon on peut passer par `xhost` mais c'est à éviter).

Il faudra aussi déclarer la variable `DISPLAY` :

```
export DISPLAY=:0.0
```
