So I have a recent(2 month) install of antergos with gnome shell.
By default it's using x11 instead of wayland (
echo $XDG_SESSION_TYPE return
Wayland was already install but not weston, so I installed it using pacman.
Lightdm was also by default but I move to gdm because I think I need to use gdm to use wayland.
On the login screen I have a choice between gnome/gnome with xorg. I always choose gnome but it's still using x11.
I'm using an intel nuc i3 4th generation.
