display not turned on by kernel on boot
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
During boot, where you enter the disk password, and the Fedora logo is
displayed, the second one stays blank. It does come out of powersave, but stays
blank rather than showing the Fedora logo and password entry etc. It comes on
properly when GDM starts up. See the two attached images - one with the fedora
boot logo, the other with the GDM screen (the actual input screen is on the
laptop display, so not visible).
This is a regression, but I cannot exactly say when it was introduced. I know
it works on 4.13 (I installed this due to the other bug I'm about to file), and
I believe it still worked on 4.15, but I don't have that installed now to test.</pre>
