Product xorg
Version unspecified
Hardware Other
OS All

Starting with fedora 28 and going through fedora 30, the nouve=
au driver
produces a bad signal when trying to display X on my LG OLEDB6P 4K televisi=
on.

Weirdly, with what is presumably the same driver, it displays a full UHD
resolution when running wayland rather than X. (I really don't understand w=
hy
something as low level as the video timing would be different between wayla=
nd
and X, but if someone does know, they probably know where the bug is too :-=
).

This isn't restricted to fedora either. I've just been testing a multi-boot=
 USB
stick, and the drivers on the ubuntu 19.04 live CD and the System Rescue CD
6.0.3 produce the same "bad signal" errors on this monitor.

For details (like X log files) see:

ugzilla.redhat.com/show_bug.cgi?id=3D1648608

If I add nomodeset and forcevesa kernel parameters, I can boot and see (low=
er
resolution) video rather than a black screen.

Switching to the nvidia binary drivers makes the display work properly agai=
n.

Booting the USB stick on different systems with more conventional resolution
monitors, nouveau works fine.

FWIW I have a LG C7P which I tested with a GM206 and GP107. Sl=
ightly different
than your setup, but comparable.

I used this setup for bringup of HDMI 2.0 support, available in kernel 4.20.
HDMI 2.0 is required for 4k@60 over HDMI.

Looking at those logs, you appear to be using modeset instead of
xf86-video-nouveau (note how it says "modeset" instead of "N=
OUVEAU"). The logs
make it look like modeset is trying to use a 3840x2160 594MHz mode. This
requires HDMI 2.0 to work (and should have been filtered out, but nonethele=
ss
is the modeline presented).

I'd recommend (a) using xf86-video-nouveau [RH has made local changes to th=
is
driver to not load, but I believe this to be a very bad idea, you can overr=
ide
with an xorg.conf iirc], and (b) updating to a 4.20+ kernel so that you get
HDMI 2.0 to work to get access to the higher refresh rates.
