I wanted to try to run Wayland + KDE 6 plasma on FreeBSD 14.1. I’ve created the following tutorial that unfortunately has some errors inside,since the project does not work.

The steps that I have taken are the following :

1 – added user to the wheel and video groups :

sudo pw groupmod wheel video -m marietto

2 – sysrc :

sudo sysrc -f /etc/rc.conf kld_list+="nvidia-modeset nvidia-drm linux linux64 i915kms"

3 – installed the following packages :

==> pkg install --glob "plasma6-*"
==> pkg install --glob "kf6-*"
==> pkg install plasma-wayland-protocols plasma6-xdg-desktop-portal-kde kf6-breeze-icons-6 kde6-devel

4- removed these packages :

pkg remove xdg-desktop-portal-wlr wlrobs grim slurp wlr-which-key wayland-protocols wayfire wf-shell wayfire-plugins-extra

5 – created a startup script called start-kde6 :

#!/usr/local/bin/bash

[ -d $XDG_RUNTIME_DIR ] || mkdir -m 700 -p $XDG_RUNTIME_DIR


export $(dbus-launch)
systemsettings
exit

# [ -d $XDG_RUNTIME_DIR ] || mkdir -m 700 -p $XDG_RUNTIME_DIR

exec dbus-launch --exit-with-session ck-launch-session startplasma-wayland 2> log

6. made it executable :

 chmod +x start-kde6

7. rebooted the machine and logged in as normal user and ran the startup script :

./start-kde6

I see the error below and it does not work :

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimal, offscreen, vkkhrdisplay, vnc, xcb, wayland, wayland-egl.

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.
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimal, offscreen, vkkhrdisplay, vnc, xcb, wayland, wayland-egl.

I read that this problem can be fixed by installing the package libxcb :

root@marietto:/home/marietto # pkg install libxcb

but in my case it is already installed :
