--- Comment #19 from Jason Antman <jason at jasonantman.com> ---
I'm also experiencing this issue, on Arch Linux kernel 5.0.3 running on a Dell
Precision 5530

BIOS 1.3.0 (07/12/2018)
Intel(R) Core(TM) i5-8400H CPU @ 2.50GHz (family: 0x6, model: 0x9e, stepping:
0xa)
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Mobile)
01:00.0 3D controller: NVIDIA Corporation GP107GLM [Quadro P1000 Mobile] (rev
a1)

I've tried building a kernel package for Arch with Mark's patch applied (
https://github.com/jantman/arch-pkgbuilds/tree/master/linux-precision5530 for
PKGBUILD and source, binaries linked from
http://archrepo.jasonantman.com/current/index.html ), but when running with
that patched kernel and the ``force_edp_wide=1`` parameter set, I see no real
difference in behavior from my previous ~35 hours struggling with video on this
machine: external displays work fine, eDP is just backlight and black screen.

Would it be possible for someone who's verified this patch to post the details
of their kernel parameters and driver versions/config?
