Example from 2020: Running Ubuntu with two displays each of which has a different scaling factor requires switching to Wayland, because on X11, any window that touches the edge of one of the displays will run unusably slowly. (I don’t know why.) A non-technical “typical desktop user” would never have figured this out.
This is on a fully supported Linux machine (XPS 13 9300 Developer Edition).
Well, thats mostly due to Ubuntu still defaulting to X. Fedora switched to Wayland by default back in 2016 and even RHEL 8 (released 2019) defaults to Wayland.
I feel like that just reinforces my point. Figuring out which random unsupported distro to install on the Linux laptop you bought is even less feasible for non-technical users than choosing a different login session on Ubuntu.
