Hi,
I've installed Debian 13 on a VirtualBox VM with the KDE desktop. At GUI
login sddm let me to choose if I want to start a Plasma session with X11
or Wayland. Choosing Wayland, what make me wondered is that a Wayland
server process seems missing:
~$ ps wwax |grep sddm
1081 ? Ssl 0:00 /usr/bin/sddm
1988 tty2 Ssl+ 0:00 /usr/lib/xorg/Xorg -nolisten tcp
-background none -seat seat0 vt2 -auth /run/sddm/xauth_MsOstO -noreset
-displayfd 17
2103 ? S 0:00 /usr/lib/x86_64-linux-gnu/sddm/sddm-helper

--start

~$ ps wwax |grep wayland
2103 ? S 0:00 /usr/lib/x86_64-linux-gnu/sddm/sddm-helper

Looking at the description of "xwayland" package it doesn't seem to be
the Wayland parent process:
Description-en: X server for running X clients under Wayland
This package provides an X server running on top of wayland, using
wayland input devices for input and forwarding either the root window or
individual top-level windows as wayland surfaces.
So, how is the Wayland graphical server implemented? I was expecting a
row such as:
1988 tty2 Ssl+ 0:00 /usr/lib/xorg/Xorg -nolisten tcp -background
none -seat seat0 vt2 -auth /run/sddm/xauth_MsOstO -noreset -displayfd 17
but referred to the Wayland server. Thank you very much for any answer.
Kind regards,
