Working Configuration for Wayland Auto-Login?

[yasu]

Hi!

Does anyone have a working example configuration that enables Wayland
Auto-Login?

I tried to use:
  (auto-login-user "yasu")
  (auto-login-session "gnome.desktop")

by guessing from the description at: 
https://guix.gnu.org/manual/en/html_node/X-Window.html

But whenever I added those below the remember-last-user? line at:

              (service sddm-service-type
                       (sddm-configuration
                         (display-server "wayland")
                         (remember-last-user? #t)
                         ))

The session changed to X11, and was not Wayland anymore.

I have just noticed that Wayalnd is way faster than X11 for my terminal
program Kitty.   The mouse cursor seems much smoother as well.

Let me paste my system description at the bottom.

Cheers,
Yasu
