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:

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.
