The default session uses wayland. You can select X from the login screen, does it fail the same way?

Windows, fonts etc are not scaled properly on the external monitor (too large, etc), and the only workaround I've found with earlier versions and other distros is to set the laptop display to 1920x1080 mode, so that's what I'm trying here as well. However, when doing that, the X (wayland, not sure if the package is correct here) session crashes and brings me back to login screen. So to summarize: connect the external monitor, go to Settings > Devices > Displays, click primary built in display, observe that it shows Resolution 3840x2160 (16:9) and Scale 200%, change resolution to 1920x1080 (16:9), click Apply --> crash.
