[lightdm] Ecran noir au démarrage

[Maxime_]

Bonjour

J'ai installé archlinux puis i3 qui fonctionne correctement (a priori) en l’appelant avec xinit (en faisant startx).
J'ai ensuite installé lightdm et lightdm-gtk-greeter.
J'ai ajouté la ligne greeter-session=lightdm-gtk-greeter dans /etc/lightdm/lightdm.conf
Et j'ai activé lightdm au lancement d'arch avec systemctl enable lightdm et j'ai redémarré mon ordinateur.
Il démarre bien mais au moment de lancer lightdm l'écran reste noir (d'ailleurs mon écran semble même ne plus recevoir de signal). Après un certain temps j'essaye de changer TTY et quelque chose s'affiche:
On peut distinguer les écritures blanches sur fond noir mais très bruitées et deux lignes colorées horizontales. Je ne parviens pas à écrire quoi que ce soit et il en va de même pour tous les TTY.

Je boot alors sur une clée arch, je monte mon disque et je chroot dessus. Je désactive lightdm avec systemctl disable lightdm et je reboot. Je peux accéder à mon Linux normalement et lorsque je lance systemctl start lightdm il fonctionne correctement mais j'ai toujours le même problème quand j'essaye de l'activer (systemctl enable lightdm)

Je précise tout de même que les dimensions de mon écran sont exotiques (3440x1440).

Je ne sais trop que dire d'autre..
J'espère que ce problème parlera a quelqu'un car je ne parviens pas à le résoudre et google ne m'a pas beaucoup aidé :/

Merci,

Salut,

On dirait que tu as un problème avec la configuration de tes locales
Regardes ce que donne la commande "localectl"
En fonction de son retour ajustes en te servant de la page du wiki:
https://wiki.archlinux.fr/Locale

[Maxime_]

En effet X11 Layout n'était plus définit, j'imagine que c'est parce que j'ai réinstallé xorg en désespoir de cause..
J'ai reparametré mes locales mais le problème perciste:

Tu as pas mal des erreurs dans ton log indiquant qu'il y a un souci avec ton pilote graphique, est-ce que "nouveau" est bien installé ou bien les pilotes nvidia ?

Super c'était ca.
Merci !
