This is on a Lenovo Ideapad Y700, running bumblebee to switch between intel
graphics and the discrete nvidia gpu. Running intel-virtual-output produces the
following error:


tkelman@linux:~> intel-virtual-output -v
intel-virtual-output: version 2.99.917
display_open((null))

:0: dri3_active?=0
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
      after 20 requests (20 known processed) with 0 events remaining.


Searching for this led to https://bugs.freedesktop.org/show_bug.cgi?id=89172
and http://lists.x.org/archives/xorg-commit/2015-February/037632.html, so I
made by own branch of the package on OBS at
https://build.opensuse.org/package/show/home:kelman:branches:openSUSE:Leap:42.1:Update/xf86-video-intel
to test the patch. Seems to at least fix this error. I'm not sure of the exact
procedure in where to submit this patch to, hence I'm opening this issue.

(and continues from there, which I think means it's working - I have other
issues with external displays and suspend/resume on this laptop, for which I'll
probably go to the forums for debugging suggestions)
