Bonjour,
A chaque démarrage de KDE l'écran s'affiche en 1024x768.
Je dois aller dans la configuration système pour remettre le 1920x1200.
Je suis sous Mageia 3 avec KDE 4.10.2.
Voici mon fichier xorg.conf.
Mais je pense que KDE va cherhcer ses infos de lancement ailleurs et que c'est ce fichier qu'il faudrait modifier.
J'ai un i7 3770 avec puce hd4000 pour l'affichage et pas de carte graphique dédiée.
