Errors while running optirun/primusrun

[Fuxino]

I am actually able to run applications with optirun/primusrun, but I get some errors in the logs anyway.

See my previous bug report for my system setup and configuration: #696

Are these errors something I should worry about or I can safely ignore them (given that optirun seems to be working as expected anyway)?

I get the same errors on Debian Stretch but I'm not able to use optirun/primusrun:

$ optirun glxgears -info
[ 1751.565102] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) systemd-logind: failed to get session: PID 1962 does not belong to any known session

[ 1751.565129] [ERROR]Aborting because fallback start is disabled.
$ primusrun glxgears -info
primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) systemd-logind: failed to get session: PID 1962 does not belong to any known session

@Fuxino They are harmless, you can ignore them (ACPI warning is NVIDIA not respecting ACPI standard, systemd one is now ignored in bumblebee-git code and fixed on systemd side, the DRM one is harmless and due to how X.org works).

@ChristianBeer Please open a new issue with more logs (/var/log/Xorg.8.log at least).
