<pre>DRM tip tree, commit 90b59df999a1 ("drm-tip: 2018y-10m-15d-20h-57m-27s UTC
integration manifest")
Fedora 28 system on an HP EliteBook Folio G1 with Intel(R) Core(TM) m7-6Y75
CPU, x86_64 of course.
I have two external monitors connected:
* one directly by USB-C display port cable
* one via docking station (<a href="https://www.iogear.com/product/GUD3C01/">https://www.iogear.com/product/GUD3C01/</a>), connected
with HDMI
Both screens frequently go completely blank. Of course now while I was waiting
for it with the camera turned on it didn't happen, but basically it just all
goes completely black and the displays turn off the backlight temporarily.
This is a regression, but I cannot exactly say when it was introduced. I know
it works on 4.13 (which I installed because of this bug...), and I believe it
still worked on 4.15, but I don't have that installed now to test.</pre>
