Public bug reported:
This system has a 4k laptop screen with resolution 3840x2160, and an
external HP monitor connected via HDMI, resolution 1920x1200. 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.
