Hi,

I've been breaking my head trying to get Bumblebee to work. After some generous help on #bumblebee IRC channel, I started doing some low-level testing, and managed to narrow down the problem.

Distro is Gentoo. Kernel version is 3.2 (I can try with 3.5 or other kernels but I suspect the problem will persist). Driver versions I have tried are 304.22, 304.43 and 304.48.

Either doing this:

# modprobe nvidia
# nvidia-xconfig -query-gpu-info

or this:

# nvidia-xconfig -query-gpu-info

from a tty as soon as the system has started (no X running though I suspect with X the results would be the same), yields this on dmesg:

[   48.990268] nvidia: module license 'NVIDIA' taints kernel.

lspci output:

01:00.0 VGA compatible controller [0300]: nVidia Corporation Device [10de:0ffc] (rev ff) (prog-if ff)
        !!! Unknown header type 7f

No bumblebee component (bbswitch, bumblebeed, optirun) was run, like I said, I managed to narrow down the problem to this.

Any ideas?

Thanks in advance
Cheers
