Configuration serveur affichage Xorg sous openMandriva 2013

Bonjour/Bonsoir la communauté,

je viens vous demander aide et conseil après plusieurs tentatives ratées pour configurer mon serveur d'affichage pour le double écran(configuration Xorg,xrandr,driver nvidia, ....).

La difficulté de la manipulation vient du fait que je cherche à configurer mon affichage double écran pour mon ordinateur portable(écran WXGA 1366*768 et moniteur LG 22EA53 1920*1080).

Actuellement, la configuration à chaque démarrage de linux se base sur le moniteur LG et duplique l'affichage sur l'écran du portable.

Une solution est d'utiliser la commande " xrandr --output LVDS1 --auto --left-of HDMI1 --auto " ce qui permet de récupérer un affichage correct et d'avoir un écran étendu mais malheureusement, ces configurations ne sont pas conservé à l'extinction de l'ordinateur.

Ne voyant pas ce qu'il faut ajouter malgré les tutoriels sur internet , j'aurais donc aimé de l'aide afin de configurer mon fichier Xorg.conf correctement afin si possible :
-de gérer le double écran automatiquement ("et proprement") au démarrage de linux à la façon de la commande précédente qui est satisfaisante
-de garder un affichage normal lorsque le double écran n'est pas connecté

La configuration de Xorg.conf n'est peut être pas non plus la solution la plus simple, openmandriva possède dans son panneau de configuration un moyen de configurer l'affichage mais je ne sais pas exactement ce qu'il faut modifier(actuellement, je suis sur un serveur d'affichage Xorg>vesa).

Mon portable est un asus K53SD SX 596V avec core i5 et nvidia get force 610M 2GB.

Merci d'avance si vous avez compris mon problème et pour la future aide,
Cordialement,Sébastien.

Voici une copie de mon Xorg.conf actuel :
