This sounds like the Wayland compositor is crashing. Some troubleshooting steps that might help to narrow down why:

• Make sure all system packages are up to date (sudo dnf upgrade)
• Next time this happens, run sudo dmesg and sudo journalctl -ab as soon as possible and post the last 30 lines or so of the output of each here. It might help explain the cause.
• If all attempts at solving the issue fail, from the gear menu on the login screen, select “GNOME on X11”. This session may lose some functionality, but is less likely to crash in the same way.

I proposed that resolution because it’s the closest to 1920x1200, but keeping a 3:2 aspect ratio.

startrek.website too. maybe it’s just a kbin-lemmy federation bug

While this new display certainly seems better (in terms of being able to use 2x scaling instead of my current 1.25x), I’d honestly prefer to have a cheaper option that’s just 1920x1280, so I don’t have to use scaling at all. I don’t care that much how “crisp” text looks.

I use https://vgy.me/ currently. Unfortunately I’m not aware of any open-source options, but vgy at least seems friendly and easy to work with.
