Configurer Xorg pour affichage LCD + projecteur

Bonjour,

Je dois faire une présentation avec un projecteur, et je me suis rendu compte que ça va pas être évident avec mon laptop tournant sous Linux (mandriva 2006).

Il semblerait qu'il va falloir configurer le fichier xorg.conf. J'ai lu le man xorg.conf, et j'en suis sorti encore plus confus qu'avant.

Est ce que quelqu'un a de l'expérience sur comment configurer xorg.conf pour qu'il sorte une image compatible avec un projecteur? Je pense qu'il faut choisir un mode d'affichage "clone" (cad même image pour le LCD laptop et projecteur, mais à des résolutions différentes).

Voici mon xorg.conf actuel (créé à l'origine par mandriva+ATI, et un peu bidouillé par moi pour faire marcher une wacom):

J'ai déjà fait plusieurs présentations, avec différents ordinateurs, et aucun problème, la sortie pour le vidéo-projecteur marchait directement.

Eventuellement, en cas de problème, brancher le video-projecteur avant d'allumer le bestiau, mais normalement pas de soucis.
Tu as déjà essayé, ou c'est juste une précaution?
# alors voila

1°) tu peux brancher le portable sur le video et n'avoir l'affichage que sur le video (il doit y avoir un bouton sur le portable pour jongler avec les affichages - FN+F8 chez dell, FN+F4 chez compaq)

le probleme est que ta resolution en 1680x1050, je ne suis pas sur que le videoprojecteur apprecie

tu peux donc baisser cette resolution dans le fichier afin de te garantir que cela passe dans ce cas.

2°) tu veux faire du double ecran, là c'est une autre paire de manche
il doit y avoir des tutoriaux sur internet pour la carte ATI.
Grosso modo ce sera en xinerama.

Google etant ton ami, les mots
linux ati xinerama
devrait pouvoir t'apporter quelques reponses.

J'ai un Sony dont l'ecran a une resolution tres particuliere (un peu style 16/9), et la seule solution que j'ai trouve est de definir deux ServerLayout: un pour le fonctionnement usuel, l'autre pour le fonctionnement avec projecteur video. Le choix s'effectue avec les options passees a startx: --layout nom_du_layout. Je ne suis pour l'instant pas parvenu a modifier Kdm pour pouvoir choisir dans Kdm quel layout utiliser.

Par contre, en layout "dual" (lcd+video), j'ai la meme resolution sur les deux (je ne suis pas parvenu a avoir une resolution differente entre le lcd et le video projecteur, d'ou un affichage LCD un peu tassé...).
