Agencement clavier bug

bonjour je viens de faire une install dubuntu et mon clavier persiste a rester en qwerty. quand je vais dans preference>clavier>agencement et au debut de ma session je recois ce message d erreure :

Erreur lors de l'activation de la configuration XKB.
Cela peut arriver pour plusieurs raisons :
- un bogue dans la bibliothèque libxklavier
- un bogue dans le serveur X (xkbcomp, utilitaires xmodmap)
- serveur X avec une implémentation de libxkbfile incompatible

Données de version du serveur X :
The X.Org Foundation
60802000

Si vous rapportez cette situation comme une anomalie, veuillez inclure :
- Le résultat de xprop -root | grep XKB
- Le résultat de gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd

j ai chercher longtemps sur le net sans trouver de reponses. pourtant je ne suis visiblement pas le seul a avoir ce probleme .

je vous donne mon xorg.conf :

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
