--- Comment #15 from Omar <omarpakker+freedesktop at gmail.com> ---
I thought I'd give this another shot to see if things have changed since the
last few kernel releases.

Tested on:
Linux Omar-PC 4.8.12-3-ARCH #1 SMP PREEMPT Thu Dec 8 16:10:23 CET 2016 x86_64
GNU/Linux

Nouveau default behaviour:
- Main GPU shortly blinks with boot information on the first screen followed by
the second screen, then both power down.
- The monitor attached to the second GPU shows the coloured stripes.
- Turning the monitor on the second GPU off and back on again made it render a
bright blue opaque screen.

Nouveau with config=NvForcePost=1 behaviour:
- All monitors power down, nothing is shown at all on either GPU.

I'll attach the output of `journalctl -b --no-pager | grep nouveau` for both
runs shortly.
