optirun fails to run

[Tomas Hamal]

Bumblebee does not work for me probably from upgrade to new testing version of debian.

$ optirun glxgears
[ 2387.483604] [ERROR]Cannot access secondary GPU - error: [XORG] (EE)

[ 2387.483655] [ERROR]Aborting because fallback start is disabled.

I tried set
KernelDriver=nvidia
and
KernelDriver=nvidia-current
I have nvidia-current module in my system but both versions of bumblebee.conf does not work.
I tried set BusID in xorg.nvidia.conf but it didn't help also.

$ cat /proc/cmdline
