With nvidia driver v530.41.03, X11 and the framebuffer for getty are only able to serve one screen, the 2nd one gets detected and controlled by X11, but will stay black.
With sway and those settings, though, both displays will show output, albeit the 2nd display will sometimes go black for a second before coming up again.

exec systemd-cat sway --unsupported-gpu
Tried with Archlinux’ 6.3.3 & 6.2.13 kernels.
Both displays get served by EFI and work fine on Windows.
Driver 525.85.05 works fine, but dkms will fail with any kernel >= 6.3.
Can confirm it works fine with 6.2.13, LTS 6.1 & LTS 5.15.
