Public bug reported:
When I built a new PC with Kubuntu 22.04 LTS, I carried over my recently
purchased GeForce RTX 3060 and copied over the Xorg.conf that was doing
perfectly well for me in 20.04 LTS, containing the following line:
Option "metamodes" "HDMI-0: 1280x1024 +3200+0, DP-3:
1280x1024 +0+0, DP-1: 1920x1080 +1280+0"
(Bear in mind that, due to a history of bugginess in KScreen2 and how it
interacts with Plasma panel layouts, I disable it in the Background
Services control panel and do my best to lock down the allowed layouts
and resolutions in Xorg.conf.)
This technique has been working for me for close to a decade, with my
previous video card being a GeForce GTX750 and, if I remember correctly,
I was also using it with the GeForce GT430 I was using before that, and
with Kubuntu and Lubuntu versions going back to at least Kubuntu 16.04
LTS and likely to Lubuntu 14.04 and possibly even Lubuntu 12.04.
However, much to my dismay, it appeared to have no effect, and the
system was still assigning a virtual layout that didn't match the
physical arrangement of the monitors.
Eventually, I realized from /var/log/Xorg.0.log that my metamodes line
WAS getting set, but, for reasons I still have no idea how to diagnose,
something else was overriding it and resetting the metamodes line back
to the undesired default, with unlocked resolutions and an incorrect
monitor layout.

I've created a /etc/X11/Xsession.d/01-fix-the-damn-ignored-metamodes

...though that doesn't fix the monitor layout at the login screen and
it's not possible to work around the forced changeability of the
