x11 forwarding from WSL2 to remote machine

Question

I am trying to use x11 apps on my Mac from WSL2, but whenever I ssh into the machine I get this warning:

X11 forwarding request failed on channel 0

And echo $DISPLAY returns blank.

In the server I've tried editing the X11 options in sshd_config file, alternated between yes and no on X11 UseLocalhost , edited AddressFamily to inet, used export DISPLAY=localhost:0.0 . Nothing works.

So far I've managed to use X11 on the Windows machine where WSL is installed with VcXsrv, but never remotely from an external machine.

Answer 1

So I figured that what I was doing wrong was that I followed this guide : what this actually does is that when I ssh I'm connecting to Windows first, which then prompts the ubuntu shell (or something like that).

So I got rid of that configuration and set up connection directly to the Ubuntu ssh server, and presto, x11 apps work like a charm.
