An answer to How to forward X over SSH to run graphics applications remotely? explains how to forward GUI applications via an X11-compliant display server (like XOrg).

However, I see no equivalent for accessing remote systems using solely Wayland compositors on both ends. Does it exist, or must a combination of X11 and/or XWayland and Wayland be utilized?

waypipe is the closest equivalent. It is not raw Wayland-over-SSH, as Wayland is not primarily a network-oriented protocol – as I understand, it relies heavily on shared memory (whereas in X11 that's completely optional) – but it's probably as close as you can get.

$ waypipe ssh foo@bar

Some compositors, such as GNOME Shell, now integrate RDP and/or VNC directly into the compositor; it's likely to provide better performance.

  • same problem here but your solution causes "WAYLAND_DISPLAY not set, exiting". Do you have more details ? Commented Jun 5, 2024 at 8:42
  • @user3732793: Do you get the message from local waypipe or from the remote program? Commented Jun 5, 2024 at 8:53
  • in the local console when conneting to the remote machine like that Commented Jun 5, 2024 at 9:52

    @user3732793: It has Wayland for its remote display, but nearly all of the actual apps you'd be running are either dual X11/Wayland compatible or even X11-only, so if that's what you're looking for – just use ssh -X -Y. (After all, the whole point of X11 forwarding is that it doesn't use the remote display – it connects to your local one – so whether the remote display is Wayland or X11 does not matter.) Just keep the superuser.com/q/1843704 issue in mind when doing so. Commented Jun 5, 2024 at 10:05
