How to get X-windows working with WSL 2 for things such as gtrace

Essentially add this to the end of .bashrc file in the Linux container.

export DISPLAY=$(awk '/nameserver / {print $2; exit}' /etc/resolv.conf 2>/dev/null):0
export LIBGL_ALWAYS_INDIRECT=1

This should have an associated firewall rule but to check it out and getting it to work under initial conditions, start X-windows allowing any connection, but this is very wrong so only do for the first test.


Currently the only need I have for X-windows with an Linux OS on WSL 2 is for running gtrace/0 with SWI-Prolog.

While it took a few hours and a few false starts and some attempts that partly worked, what I currently do is detailed in Remote development using Docker, WSL 2, Visual Studio Code and X-windows server of this post.

Aaah, very nice. Works!

Thanks, Eric!
