EDIT 2025-02-22: Solved by installing LightDM with the GTK greeter. Worked out of the box with zero config changes.
Running a multiseat setup with two GPUs, one Nvidia (GTX 1070) (seat0) and one AMD (RX 6650) (seat-hoodie).
I loginctl attach'd all of the GPU related devices per the wiki (https://wiki.archlinux.org/title/Xorg_multiseat), as well as a USB port with a hub plugged in for keyboard/mouse/etc.
The greeter works exactly as expected, I get two separate login screens, however logging in on the second seat just causes the display to freeze.
According to journalctl, the session *does* start, including systemd-user, KDE services, etc., just nothing shows up. The primary display for the seat freezes on the GDM login, and the second screen goes black.
Tried with both X11 and Wayland sessions, exact same outcome.
I'm not sure how to further diagnose/debug the issue.
Since GDM itself seems to work fine, and the session starts and is correctly assigned to the seat per loginctl's output, I'm guessing maybe there's another device I'm missing?
loginctl seat-status seat0:

Got a new GPU today, Intel ARC B580. Exact same series of steps, exact same result: All of the issues related to the NVIDIA driver are now gone, however the second seat still does not get past the login pronpt. Just freezes, exactly as above.
No idea what else to try.

Tried today with SDDM (no changes from default configuration), same hat except it completely locks up /both/ sessions instead of just one,
Tried with LightDM and lightdm-gtk-greeter, also default configuration, and it just worked immediately. I am so confused why LightDM works perfectly but the other two don't. But hey! Mission accomplished!
