optirun ... don't work

sudo apt-add-repository ppa:bumblebee/stable
sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get clean autoclean
sudo apt-get dist-upgrade -y
sudo apt-get install linux-headers-generic
sudo apt-get install bumblebee

sans message particulier d'erreur, j'ai rebooté, pas de module nouveau qui traîne, j'ai essayé lee différentes manip de correction proposées sur le site ci-dessus, rien à faire :

optirun -vv glxspheres

donne :

j'utilise ubuntu 12.10 à jour avec un Toshiba P875 avec une Carte graphique Nvidia GeForce Optimus GT 630M

Pour info :
dmesg | grep nvidia
[ 48.980838] nvidia: module license 'NVIDIA' taints kernel.
[ 48.988195] nvidia 0000:01:00.0: enabling device (0006 -> 0007)

Then I make the ugly patch: https://github.com/Bumblebee-Project/bbswitch/tree/hack-lenovo#lenovo-ideapad-y470y570-and-toshiba-satellite-p870

Then

dmesg | grep bb

[ 13.672982] bbswitch: version 0.4.2
[ 13.672987] bbswitch: Found integrated VGA device 0000:00:02.0: \_SB_.PCI0.GFX0

[ 13.673036] bbswitch: No suitable _DSM call found.

et sudo cat /proc/acpi/bbswitch

cat: /proc/acpi/bbswitch: Aucun fichier ou dossier de ce type

optirun -vv glxspheres donne le même message qu'avant :
