KDE 6 + Wayland : it works or not ?

No I'm not contradicting myself, it was probably just not clearly stated...
:) -- as I said, they conflict, as they install the same
desktop in different versions...
So, don't install plasma5 if you want to use plasma6 -- the only port that
might be needed of plasma5-plasma-integration.
If you want to try to use plasma6 and try to get wayland up, make sure to
remove plasma5* and just install the plasma6-plasma
package.

I really recommend to use this tree instead of main:
https://github.com/freebsd/freebsd-ports-kde/tree/kde-it_goes_to_6


You can then create a shell-script ala

###
#!/bin/sh
export QT_DEBUG_PLUGINS=1
# export QT_WAYLAND_SHELL_INTEGRATION=xdg-shell
export WAYLAND_DEBUG=1
# export XDG_SESSION_TYPE=wayland

ck-launch-session dbus-run-session truss /usr/local/bin/startplasma-wayland
>& /memory/startplasma.log
####

to try to run plasma... you likely get an output like

###

[...]
qt.core.library:
"/usr/local/lib/qt6/plugins/platforms/libqwayland-generic.so" loaded
library
Failed to create wl_display (No such file or directory)
qt.qpa.plugin: Could not load the Qt platform plugin "wayland" in ""
even though it was found.
qt.core.library: "/usr/local/lib/qt6/plugins/platforms/libqxcb.so"
loaded library
qt.qpa.xcb: could not connect to display :0
qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to
load the Qt xcb platform plugin.
[...]

###
before it fails :/
