I'm currently running Weston as the main display server, so that is known :) Well, my fork of weston actually: https://github.com/myfreeweb/weston Sway 0.x also worked, 1.x (master) should work too, unless they broke something. The only unknown is KDE KWin ("might just work with ConsoleKit2?"). I guess I should look into that, but I'm busy with other stuff.. GNOME is definitely not supported ("needs patching to support ConsoleKit2 or some other alternative to systemd-logind"). That's actually the main porting issue in general, many compositors use logind, some (like gnome) *only* use logind. > If that's correct, then assuming that I compiled my ports with > support for Wayland enabled, and assuming further that I have 11.2 > installed, what else would I need to do to be able to test this? > > I guess I need to compile and install drm-next-kmod or > drm-stable-kmod.

For windowed mode, you don't need anything special. But for *anything on Vega*, you do need drm-next-kmod. LinuxKPI updates required for drm-next-kmod 4.15 have indeed been merged into 11-STABLE: https://svnweb.freebsd.org/base?view=revision&revision=335436 Vega support is still not as stable as <=Polaris, btw: https://github.com/FreeBSDDesktop/kms-drm/issues/76 https://github.com/FreeBSDDesktop/kms-drm/issues/71 > Please correct if my guesses are wrong.
