SUMMARY

For my user, spiderunderurbed, I get this issue:
https://pastebin.com/LGMZ66xE

Multimonitor wayland does not work with my primary user spiderunderurbed is my primary user and a rarely play around with user specific configuration, so this could likely be a configuration option that stayed back from a few updates ago, cache, (but i removed .cache) or something I would perfer to fix on my user, and I think this might not be a issue with the fact my main user was in use for awhile but it could be a issue that could happen to anyone. This does not happen on other users, like another user i have called "jellyfin."

STEPS TO REPRODUCE:
UNKNOWN at the moment

OBSERVED RESULT
I observed that the second monitor would flicker with a hdmi connection and fail, 3 times, then crash and return to sddm. display-manager was not being of much help, here is a log with display-manager:
https://pastebin.com/MQGww7Bs
^ long one (ignore the early entries where it mentions the gnome keyring, I had to remove gnome as the keyring was crashing sddm, but later onwards is where my bug manifests)

EXPECTED RESULT
Wayland should start, on both of my monitors, my laptop screen and my display. Like it does when I am on the user jellyfin, maybe there is a simple fix for me, but there should also be a change made so this issue doesnt happen with anyone else.

I do use a predator helios 300 with a nvidia dpu and igpu but this is not a limitation when it comes to multimonitor support I discovered, since it works with another user, however if you suspect this does have something to do with my computer, I mistakingly assumed it was a hardware issue and a few months earlier i filed a bug report under that assumtion:

I figured out what caused this issue, and what caused this issue shouldn't have, at least there should have been better logging, I made a nix script which copies a icon zip or whatever format into a directory, some kde directory for icons, it ends in this:
share/icons/uos-fulldistro-icons

I think it was under .var or /usr/
anyways, there was no reason for me to think that this caused my multimonitor issues, here is the full nix script as I tried to package a new icon theme from my distro, at some point ill attach a backtrace and then a fix is probably needed or better logging to identify icons which aren't properly installed. Here is the link to the package script:
