There are many similar errors on here, but none quite seemed to match my issue.
[ERROR]Cannot access secondary GPU - error: [XORG] (EE)
I have PRIME running, and I can use the PRIME profile to switch between my Intel and my NVIDIA 970M successfully. I've got nvidia-375 drivers installed (latest).
The only piece of the puzzle that doesn't work is bumblebee now.
