13.2 and 14.1

--- Description ---
Hello.

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)
exec dbus-launch --exit-with-session ck-launch-session startplasma-wayland

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 :

Updating FreeBSD repository catalogue...
FreeBSD repository is up to date.
All repositories are up to date.
Checking integrity... done (0 conflicting)
The most recent versions of packages are already installed

It may be a bug in detecting the library :

Description    :

The xcb-util module provides a number of libraries which sit on top of
libxcb, the core X protocol library, and some of the extension libraries.
These libraries provide convenience functions and interfaces which make the
raw X protocol more usable.  Some of the libraries also provide client-side
code which is not strictly part of the X protocol but which have traditionally
been provided by Xlib.
The util-cursor module implements the XCB cursor library, which is th XCB
replacement for libXcursor.

I'm on FreeBSD 14.1 ; I don't have the exact requested packages. Please give a
look here :

There's a recent unanswered post on the FreeBSD forum which claims the library
is installed :
