Bonjour! désolé je poste ici car le forum Linux y'a 0 connecté(s), et que le dernier message date du 18 mai ... 
en gros un pote m'as installé Linux Mint sur mon pc portable, pour que je me forme à l'utiliser, et je comptais travailler (développement web) avec en utilisant du coup mon moniteur d'écran pour avoir double écran et être dans de bonne condition
sauf que le port HDMI n'est pas reconnu ...
voici la réponse de la commande 'xrandr' :
xrandr: Failed to get size of gamma for output default
