Solved X11 forwarding without ssh

[Holger]

I have another computer to which I connect via serial console. It is connected to the network, but I would like to stick to the serial console and not use SSH when running graphical applications.

The local IP address on which the X-Server runs in 192.168.178.20. On the remote machine I tried

export DISPLAY=192.168.178.20:0

But this does not work (“Could not connect to display”).

I searched the web, found some information about xauth, but nothing really worked.

Any ideas?

You need to enable TCP listening on the Xserver (it has been disabled by default for decades).

Generally pass the -listen tcp argument to the Xorg server.
