Hi ael

Set 
    X11Forwarding yes

on the Devuan machine in /etc/ssh/sshd_config.d/local.conf (you shouldn't
change /etc/ssh/sshd_config -> eases next upgrade for you). Restart ssh.

In sshd_config the defaults are mentioned as comments.

PS: To debug use ssh -vv on the client side. For X11 forwarding its worth to
compress, even on a LAN: ssh -XC machine3
