Try sudo systemctl enable wslg-xwayland.socket

Not useful, there're several player in this issue:

  1. wslg-xwayland.socket / wslg-xwayland.socket: Create a socket at /tmp/.X11-unix
  2. tmpfiles.d/wslg.conf (check both under /etc and /usr/lib): Link /tmp/.X11-unix to /mnt/wslg/.X11-unix
  3. systemd's own /usr/lib/tmpfiles.d/x11.conf: Remove all file under /tmp/.X11-unix
  4. WSL's own bind mounting from /tmp/.X11-unix to /mnt/wslg/.X11-unix

For me, 4 is conflicting with 1 2 3, as wslg-xwayland will overwrite the original socket, wslg.conf will do a symlink, systemd will delete tmp folder, all of these will kill the original X11 socket. There're several working cases:

  1. Disable 134 & Use 2 only: DISPLAY variable will be set correctly
  2. Disable 234 & Use 1 only: DISPLAY variable will be empty, but manually setting it to :0 would still make wslg working
  3. Disable 123 & Use 4 only: the original, non-genie case, OFC working

So I chose to disable 134: I killed 4 by umounting /tmp/.X11-unix before genie, and killed 1 by masking wslg-xwayland*, and make sure there's /etc/tmpfiles.d/wslg.conf

In theory, 1 should not exist alongside 2 on a clean genie installation; 2 was intended as a replacement for one. 2 also shouldn't clash with 3, because systemd-tmpfiles consolidates the various .confs before acting on them.

Not sure about 4. I see a symlink there pre-genie, not a bind mount.
