I have problem with optirun command on Ubuntu 12.10 installed on notebook DELL M6600. In the BIOS I have enabled Optimus technology. I have two graphics:

lspci -vnn | grep '''[030[02]]'

Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller])

NVIDIA Corporation GF104 [Quadro 4000M] [10de:0e3b] (rev a1) (prog-if 00 [VGA controller])

I have installed nvidia drivers:

dpkg -l | grep nvidia

I think I got the same problem. When I intalled bumblebee, it did not recognise my discreet card. Looking for this problem, I found that Ubuntu uses the key nvidia instead of nvidia-current to refer to the drivers of nVidia.

So try this:

Make a backup of the file /etc/bumblebee/bumblebee.conf

sudo cp /etc/bumblebee/bumblebee.conf /etc/bumblebee/bumblebee.conf.backup

(for example)

Edit that file (use the editor you want, for example gedit):

sudo gedit /etc/bumblebee/bumblebee.conf

Go down to the section [driver-nvidia].

There, change the value of

KernelDriver=nvidia-current

to

KernelDriver=nvidia

and

Module=nvidia-current

to

Module=nvidia

Save the file and reboot.

Now try again:

optirun -vv -debug glxspheres

If you get your same error, restore the configuration file:

sudo cp /etc/bumblebee/bumblebee.conf.backup /etc/bumblebee/bumblebee.conf

Have Luck.
