comment réparer "Le démon Bumblebee n'a pas encore été démarré ou le chemin du socket était incorrect"?

NVidia avec Optimus en conflit dans Ubuntu 12.04

Je viens d’acheter un nouveau Ultrabook Dell XPS 14 équipé d’un NVIDIA GeForce GT 630M. Ainsi, à la suite de certaines indications que j’ai trouvées dans la documentation disponible en ligne, j’ajoute le bpablebee ppa et le bumblebee installé ainsi que nvidia-bumblebee.

Mais quand j'ai essayé d'utiliser la carte nvidia pour exécuter quelque chose, j'ai eu cette erreur:

optirun -vv firefox
[  476.380739] [DEBUG]Reading file: /etc/bumblebee/bumblebee.conf
[  476.381430] [INFO]Configured driver: nvidia
[  476.381498] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect.
[  476.381513] [DEBUG]Socket closed.
[  476.381534] [ERROR]Could not connect to bumblebee daemon - is it running?

Voici quelques fichiers de configuration:

/etc/bumblebee/bumblebee.conf

## Server options. Any change made in this section will need a server restart
# to take effect.
[bumblebeed]

# for X to be ready is too long and don't need power management at all.

[optirun]
# The method used for VirtualGL to transport frames between X servers.
# Possible values are proxy, jpeg, rgb, xv and yuv.

# is not available?
AllowFallbackToIGC=false


# Driver-specific settings are grouped under [driver-NAME]. The sections are
# parsed if the Driver setting in [bumblebeed] is set to NAME (or if auto-
# detection resolves to NAME).
# PMMethod: method to use for saving power by disabling the nvidia card, valid
# values are: auto - automatically detect which PM method to use
#         bbswitch - new in BB 3, recommended if available
#       switcheroo - vga_switcheroo method, use at your own risk
#             none - disable PM completely

J'ai supprimé les mises à jour nvidia-current parce que l'unité ne pouvait pas commencer avec elle installée.

En passant, j'utilise la dernière version d'ubuntu (12.10) 64 bits; et j'ai essayé de réinstaller bumblebee comme 3 fois.

Pouvez-vous m'aider à réparer cette erreur? Y a-t-il d'autres informations dont vous pourriez avoir besoin pour m'aider?

Merci d'avance.
