Merci pour les réponses,
Pour ce qui est des xorg:
livna-display-config me crée ce xorg.conf :
# Xorg configuration created by livna-config-display
Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Synaptics" "CorePointer"
EndSection
Section "ServerFlags"
Option "AIGLX" "on"
EndSection
Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "fr"
EndSection
Section "InputDevice"
Identifier "Synaptics"
Driver "synaptics"
Option "Device" "/dev/input/mice"
Option "Protocol" "auto-dev"
Option "Emulate3Buttons" "yes"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "vesa"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection
Section "Extensions"
Option "Composite" "Enable"
EndSection
il m'indique 'vesa' comme pilote,je ne comprends pas pourquoi , ca devrait être fglrx
mais j'ai beau le laisser tel quel ou le modifier( mettre fglrx à la place de 'vesa' , rajouter des modules,...) au redémarrage le serveur graphique ne démarre toujours pas
mon xorg devient donc ca: (il est pratiquement comme celui de dessus sans la section Extensions et ServerFlags)
# Xorg configuration created by system-config-display
Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Synaptics" "CorePointer"
EndSection
Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "fr"
EndSection
Section "InputDevice"
Identifier "Synaptics"
Driver "synaptics"
Option "Device" "/dev/input/mice"
Option "Protocol" "auto-dev"
Option "Emulate3Buttons" "yes"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "vesa"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection
j'ai aussi essayé de faire un xorg d'après ce qui a été écrit sur le forum comme ceci:
Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Synaptics" "CorePointer"
EndSection
Section "Files"
ModulePath "/usr/lib/xorg/modules"
EndSection
Section "Module"
Load "glx"
Load "dri"
Load "extmod"
EndSection
Section "ServerFlags"
Option "AIGLX" "on"
EndSection
Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "fr"
Option "XkbVariant" "latin9"
EndSection
Section "InputDevice"
Identifier "Synaptics"
Driver "synaptics"
Option "Device" "/dev/input/mice"
Option "Protocol" "auto-dev"
Option "Emulate3Buttons" "yes"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "fglrx"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection
Section "Extensions"
Option "Composite" "Disable"
#Option "Composite" "Enable"
EndSection
Mais celui aussi ne fonctionne pas.
J'ai bien la section 'Screen' pourtant.
D'où est-ce que ca pourrait venir ce problème...
