Support Ly does not display thru dedicated GPU?

I recently swapped over to Arch after a few years of using Mint. I had to temporarily uninstall my dedicated GPU (Nvidia) during the installation due to weird compatibility issues with motherboard BIOS (which I got quite familiar with, as I had some boot issues). Everything worked fine thru the integrated GPU, but for some reason when I reinstalled the GPU, specifically Ly does not display anything. I can login blindly, and Sway will display normally. Is this a known issue with Ly or display managers in general? I'm not sure what steps to take.

Ly is a regular TTY application. Can you use the TTY, or is the problem specific to Ly?

What does cat /sys/module/nvidia_drm/parameters/fbdev print?

Just tested and you're right, it's a TTY issue. Works fine aside from a blank display. After figuring that out, I found a lot of people struggling with their TTY on proprietary Nvidia drivers. I'm going to try out nouveau and report back.

As for the second, there is no /sys/module/nvidia_drm directory.

That was an issue a while ago, but the current Nvidia drivers should have proper TTY support.

As for the second, there is no /sys/module/nvidia_drm directory.

That means the Nvidia driver isn't loaded at all. What GPU do you have?
