Public bug reported: The cosmic login screen flickers to black a few times on boot and then finally settles on using Xorg instead of Wayland.
I can tell because from ssh user 'gdm' is running: /usr/lib/xorg/Xorg vt2 -displayfd 3 -auth /run/user/121/gdm/Xauthority -background none -noreset -keeptty -verbose 3 and not the usual Xwayland. Also the login screen offers no choice of Xorg or Wayland sessions.
