Bonjour à tous !

J'ai voulu changer de système et tester ArchLinux en utilisant l'environnement Cinnamon, cependant, j'ai un soucis d'interface graphique.
J'ai installé les packages suivants: cinnamon gnome xorg-xinit xorg-server et malheureusement, je n'arrive pas à utiliser mon environnement graphique.

Lorsque je saisit la commande xinit, j'ai l'erreur suivante:
Code : Sélectionner tout - Visualiser dans une fenêtre à part

Par ailleurs, j'ai suivi ce tutoriel pour installé le pilote nouveau pour ma carte graphique NVidia GeForce 610M:
https://wiki.archlinux.fr/NVIDIA

Par ailleurs, lorsque je saisit la commande cinnamon-session, j'ai l'erreur suivante:

Pour être honnête, c'est quelque chose qui me dépasse totalement et je n'arrive pas du tout à progresser dans l'installation d'un environnement graphique.

Si vous souhaitez d'autres informations complémentaires, je pourrai vous les fournir
