Requirements

• ssh

On the Host

Install and run wayvnc.

1export WAYLAND_DISPLAY=wayland-1
2wayvnc

Only the localhost can access this (highly insecure) desktop sharing, at port 5900.

On the Client

You'll need to disable your main modifier key on the client while accessing the host. Edit ~/.config/sway/config, and create a new passthrough mode where the modifier key does nothing.

mode passthrough {
    bindsym $mod+c mode default
}
bindsym $mod+c mode passthrough

Reload sway to make the changes take effect.

1swaymsg reload

Use ssh to grab the host's port 5900.

1ssh -L 5900:localhost:5900 ${remote_username}@${remote_ip}

Leave that session running, and connect with vncviewer:

1vncviewer localhost:5900
