Bug#756522: bumblebee-nvidia: cannot access secondary gpu - error: Permission denied

[Sayutin Dmitry]

Package: bumblebee-nvidia
Version: 3.2.1-5
Followup-For: Bug #756522

Hello,
Want to provide details on this issue.
Optirun on any application (by root or not) results in error:

$ optirun glxgears
[ 1100.741036] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) /dev/dri/card0: failed to set DRM interface version 1.4: Permission denied

[ 1100.741095] [ERROR]Aborting because fallback start is disabled.

This probably happens by wrong xorg.conf.nvidia from the package (i haven't figured out what exactly).
Upstream also has such bugs:
https://github.com/Bumblebee-Project/Bumblebee/issues/580
https://github.com/Bumblebee-Project/Bumblebee/issues/575
But as they (the people reported issues) using ubuntu, i think it is debian package bug.
