Bug#776598: bumblebee-nvidia: Cannot access secondary GPU - error: X did not start properly

[solitone]

Package: bumblebee-nvidia
Version: 3.2.1-4~bpo70+1
Severity: important

Dear Maintainer,

I have bumblebee-nvidia 3.2.1-4~bpo7 and nvidia-driver 340.65-2~bpo on 
an amd64 architecture laptop. My kernel version is: 

$ uname -a
Linux aldous 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.7-ckt2-1~bpo70+1 (2014-12-08) x86_64 GNU/Linux

After all packages were succesfully installed, I tried and ran:

$ optirun glxspheres64

to test whether everything worked fine. I got this error message though:

[ERROR]Cannot access secondary GPU - error: Could not load GPU driver

I then edited /etc/bumblebee/bumblebeehihi.conf, and changed "KernelDriver=nvidia"
to "KernelDriver=nvidia-current", then restarted the bumblebee daemon.

I retried the test with optirun, but this time I got a different error message:

[18100.861997] [ERROR]Cannot access secondary GPU - error: X did not start properly
[18100.862071] [ERROR]Aborting because fallback start is disabled.
