Wayland/Weston with XWayland works on DragonFly

[karu.pruun]

I've tested KDE in the sense of running a KDE application (kile) using
XWayland. It's like using GNOME or XFCE or MATE to run a KDE
application.

Running a full fledged KDE with XWayland (startkde4) did not go well;
basically you already have a minimal native DE, i.e. Weston, and then
you run another DE, i.e. KDE on top of XWayaland --- KDE was
unusuable, even kile did not start; whereas running just kile as
above, i.e. just as an application with Weston gave a functional app.

The KDE effort to rewrite KDE for Wayland is documented here

https://community.kde.org/KWin/Wayland

As far as I understand all of the major desktop environments are
currently in transition of adding native support to Wayland. Until
this is done, that is, until they do not run natively under Wayland
one has to use a compatibility backend like XWayland to run
applications that rely on Xorg.

Cheers
