====== Xorg ======

Xorg est le remplaçant de XFree86.

L'installation du driver Nvidia est ici : [[nvidia]].

===== Installation =====

Le méta paquet permettant l'installation de Xorg est :
  * xserver-xorg

Il vous faudra choisir un window manager comme Gnome, KDE ou encore [[linux:XFCE]].

===== Xorg.conf =====

La configuration de xorg est réalisée dans le fichier /etc/X11/xorg.conf.

Ce fichier décrit la configuration avec plusieurs sections :
  * Monitor : Définition d'un moniteur (fréquences)
  * Device : Définition des périphériques d'affichage (carte graphique + options)
  * Screen : Association entre un monitor et un device ainsi que les définitions supportées
  * InputDevice : Définition des périphèriques d'entrée (souris, clavier)
  * ServerLayout : Association d'un ou plusieurs Screen avec les InputDevice

Voici quelques exemples :

==== Section Monitor ====
<file>
Section "Monitor"

    Option         "NvAgp" "1"
    Option         "NoLogo" "true"
EndSection
</file>

==== Section Screen ====

        Modes      "1024x768"
    EndSubSection
EndSection
</file>

==== Section InputDevice ====
<file>
Section "InputDevice"
    Identifier     "Configured Mouse"
    Driver         "mouse"
    Option         "CorePointer"

    Option         "Protocol" "ExplorerPS/2"
    Option         "Emulate3Buttons" "false"
    Option         "ZAxisMapping" "6 7"
EndSection
</file>

<file>
Section "InputDevice"
    Identifier     "Generic Keyboard"
    Driver         "kbd"
    Option         "CoreKeyboard"
    Option         "XkbRules" "xorg"
    Option         "XkbModel" "pc105"
    Option         "XkbLayout" "fr"

    Identifier     "Default Layout"
    Screen         "Screen 1"
    InputDevice    "Generic Keyboard"
    InputDevice    "Configured Mouse"
EndSection
</file>


===== Gestion Multi écran =====

Il existe de nombreuse façon de gérer le multi écran sous Linux. Voici quelques exemples.

==== 2 Ecrans sous la même session X ====
<file>
Section "ServerLayout"
    Identifier     "Default Layout"
    Screen        0 "Screen 1"
    Screen        1 "Screen 2"
    InputDevice    "Generic Keyboard"
    InputDevice    "Configured Mouse"
EndSection
</file>

Attention, il n'est pas toujours possible de lancer deux screens utilisant la même carte. Par exemple avec Nvidia, configurez plutot le Twinview.

==== 2 Layout avec chacun son ecran ====
<file>
Section "ServerLayout"
    Identifier     "Default Layout"
    Screen         "Screen 1"
    InputDevice    "Generic Keyboard"
    InputDevice    "Configured Mouse"
EndSection

Section "ServerLayout"
    Identifier     "Layout Film"
    Screen         "Screen 2"
    InputDevice    "Generic Keyboard"
    InputDevice    "Configured Mouse"
EndSection
</file>

===== Configuration avancée de la souris =====
Voir [[mouse|Configuration de la souris]]

===== Exemple de fichier complet =====

Voici ma configuration comprenant les éléments suivants :
  * Nvidia Ti 4200 avec double ecran (sur 2 layouts)
  * Souris Logitech MX510 
  * Clavier Logitech classique
