ivo log on Nvidia 367.27
Between Nvidia drivers 361 and 364, there has been some change that makes intel-virtual-output cause segmentation faults in the Nvidia X server when it is used. Since this driver version is necessary for newer Linux kernels (4.6+), it makes it pretty much impossible to use ivo on this kernel.
Here is a report of another user suffering from the same issue: https://bbs.archlinux.org/viewtopic.php?id=214257
I'm not certain if this is a bug in the Nvidia driver (i.e. I should report this to Nvidia) or if ivo is using some interface that has become deprecated or something like that. Hence I'm reporting it here first.
Thanks for reading!

Xorg log on nvidia 367.27
The patches posted here seem to work around the problem in i-v-o:
No more X server crashes.
I would greatly appreciate if this was fixed for nvidia >= version 384 (which is the earliest version which received a recent security fix) and it was ensured that the fix is deployed to Ubuntu 16.04, 17.04 or 17.10 - my preference would be the first two of those versions.
My $700 laptop is worthless without intel-virtual-output + Bumblebee.

Sincerely, that complaint is best directed at the provider of the closed source driver.

Look I know about your pain with NVidia.
I spent hours reading their forums and the complaints of people about the lack of proper offloading with computers with the Optimus configuration (Intel+NVidia GPU), and how they're doing nothing about it.
I've spent over a day googling for laptops without Optimus, and it's nowadays just impossible to find a decent device which only has an Intel card and still has a quad core, docking station support and a trackpoint instead of a shitty touchpad.
The only other option I would have is to not have a laptop, but I need a laptop to do my job.
So I would very deeply appreciate if this issue was fixed, especially considering the patch on the Bumblebee bugtracker for this issue is two lines only ;)
If you need any help from me I will try to do my best!

Accompanied with, "Works for me, but the XRRSetPanning() calls seem to be necessary in the general case, so ymmv." but zero explanation why this would be needed to work with a black box binary package. It's a rabbit hole. There's no end to it.
Life is too short to be debugging binary blobs without source.
