On Wayland, you should use the API provided by xdg-desktop-portal:
org.freedesktop.portal.ScreenCast. It is not directly related to X11
though, and should work the same no matter what windowing system you
use. Read more about it here:
Thanks. That looks reasonable to implement, at least for full-screen
sharing. I'll come back to individual windows later. If I update to
Fedora 28 do all those instructions about having to rebuild stuff for
myself and enable the features go away?
Right, no need to rebuild anything.

Ah, it works if I manually start /usr/bin/pipewire. Is that supposed to
get started automatically? Is my client (Pidgin) expected to start it
if needed? Or should I check if it's running, and just not offer screen
sharing functionality if it isn't?
