Bumblebee not working on Lenovo Thinkpad P50 with Centos 6.8-6.9 and 7.3-7.5

[wrthissell]

Dear Lekensteyn,
I am unable to get Bumblebee to work on a Lenovo Thinkpad P50 with the above mentioned Centos Versions. I am currently trying to get it to work on Centos 7.5.
gsgatlin is most graciously assisting me in resolving this issue. He now suspects that the issue involves bbswitch and he referred me to this sub-page to submit and issue.
Below is a link to the transcript of what we have tried thus far:

Bumblebee-Project/Bumblebee#974

    I want to thank you in advance for your assistance in helping us resolve this issue

Dear Colleagues,
Are there any bbswitch developers out there that may help us resolve this issue?
Thank you in advance for your assistance.

Dear Lekensteyn,
I have created a src.rpm and rpm from doudou's webpage below:

https://github.com/doudou/bbswitch/tree/nv_card_d3_using_runtime_suspend

I suspect that it will fix the issue I previously had and reported at:

#177

See below for the details:
[wrthissell@localhost ~]$ .\load.sh
[wrthissell@localhost ~]$ bumblebee-nvidia --check

nvidia.ko compiled into in the kernel tree ok.

Check bbswitch kernel module...

bbswitch is loaded into the current kernel ok.

All checks completed successfully! NVIDIA driver appears to have compiled ok.

You will note that the bumblebee build is from the gsgatlin build of the xpra-backend build of bumblebee, detailed in the:

Bumblebee-Project/Bumblebee#974
thread.

The combination of the two does not resolve my optirun issue, but it does appear to resolve the issue of turning on and off the nvidia card.
I am still pursuing a resolution of my optirun issue.
I am requesting a pull merge between the xpra-backend and the development branch in order to assist my isolation and resolution of my issue.

  Here are the src.rpm and rpms that I am working with for bbswitch:

20180827 bbswitch-0.9-1.tar.gz

 Thank you in advance for executing the pull request between the xpra-backend and the development branch of bumblebee so that I may continue to execute my debugging whilst incorporating your other debugging.
