Arch only outputting to a single monitor

Hello everyone, I installed Arch to my computer a few days ago to dualboot with Windows 10, and a day after installing I saw that it's only outputting signal to a single monitor.

I'm using Wayland and GNOME.

My monitor setup consists of 3 monitors: the first monitor, connected via DVI, which the screen is and has been always working (this one appears to be my "default" monitor, as it's the monitor used for the boot menu); the second monitor, connected via HDMI with a KVM switch (it is switched to the correct PC), which was working on first install but not working now; and the third monitor, also DVI, which hasn't been working with Arch at all. All monitors work as usual when booting to Windows, so I'm guessing that it is not a hardware issue.

Could anyone please help me out with this?

What's your GPU(s)? Did you check the display configuration settings in GNOME? Assuming the displays don't show up there at all either it's probably something more systemic and a

sudo journalctl -b | curl -F 'file=@-'  https://paste.c-net.org/

would be useful

What's your GPU(s)?

I have a 2GB NVIDIA GeForce GTX 660 Ti GPU.

Did you check the display configuration settings in GNOME?

Yes, and it is not showing any other displays, just the display settings for the one monitor (orientation, resolution, etc.).

Assuming the displays don't show up there at all either it's probably something more systemic and a

sudo journalctl -b | curl -F 'file=@-'  https://paste.c-net.org/

would be useful

I did that, and it just outputted a link. Should I send that link here?

Yes. Are you trying to use the nvidia-470xx drivers or nouveau with that? This will predate any useful Wayland work on nvidia and could be the reason and nouveau is still in a bit of a limbo state

Here is the link: https://paste.c-net.org/RickieWeekly

I believe I am using the nvidia-470xx drivers, however I am not absolutely certain; how would I check?
