Log-in gui screen blank but usable? (lemmy.ca)

Welcome :)

I'm on Pop!_OS 22.04 LTS and up to date.

I shutdown my computer with no problems last night. Today I decrypted my drive with the on-screen prompt and it followed into a solid-grey background; My 3 accounts were not displaying. Rebooting has done nothing regarding the problem. The only notable thing I've done is install drawio and thunderbird from the pop shop.

Despite this issue, I was able to press [Enter] and input my password successfully. Everything else seems to be running hunky-dory.

I read through my syslogs while scritching my chin, but I honestly have no idea what to look for this time. I scanned through my entire post-boot log entry to no avail, but I'm also a... linux noob.

Help please q.q

Oh my bad so both were external monitors, don't remember why I thought one of them was a laptop screen. At least the issue got narrowed down a bit. I haven't touched GNOME or GDM in years so I'm not sure but shouldn't you also copy your monitors.xml to /var/lib/gdm/.config/? There's also this about changing that file and which assumes the existence of a gdm user under which the gdm process runs but I'm not sure if that's applicable to Pop OS: https://discourse.gnome.org/t/how-do-you-configure-your-displays-for-gdm/13762

About the AMD APU, if it's not causing any issues it's probably not worth the hassle to disable it in the BIOS (if that's even possible), I'm not familiar with those setups but modern Nvidia GPUs can switch to the integrated GPU to save power and that's normally supported on Linux.
