GWSL-Source VS x11-over-vsock

That vsock thing can be done with GWSL/VcXsrv too. Check this out: https://github.com/nbdd0121/wsld

Install an X server in Windows (that page mentions VcXsrv and/but I recommend GWSL which also uses VcXsrv for a little nicer experience).

and GWSL https://github.com/Opticos/GWSL-Source with settings:

With OpenInWSL, possibly using alonside GWSL.

I don't know but if all you want is a working X server and you don't need Xming specifically then give GWSL/VcXsrv a try instead.

You may instead want to use an X server and I recommend GWSL for that.

I don't feel like troubleshooting that issue any further so if all you needed was GUI app support and not necessarily GPU compute capabilities (CUDA etc) then use this: https://opticos.github.io/gwsl/.

Also, if for some reason you decide that you aren't big on the idea of Wayland yet (as in if you don't have a care for the Wayland features and/or WSLg's PCIe partitioning based direct GPU access etc) then you can opt to disable the guiApplications setting in your .wslconfig file and instead install an X server (like VcXsrv, or GWSL that uses it and provides some nice to have GUI controls etc for it) and be able to set your preferred titlebar/border via the said themes from Pling etc from within your WSL distro environments themselves (install lxappearance or GNOME Tweaks Tool to set them up).

Yeah, all of that seems to be available if you use WSL1 and pair it up with an X server (GWSL is a handy FOSS package for that and the dev's OpenInWSL app makes the integration even more seamless).

Those that don't want to pay for it, checkout these two neat open source projects called GWSL & WSLD (for vsock). These days I don't care much about using the Linux GUI stuff on Windows anymore, as Microsoft is winning, but once I have to be more serious about it I'll use them again (or do something else.)

This way WSLg will be disabled but you can still use the X servers (like VcXsrv or the other tools that use it like GWSL) which can use X over TCP or X over vsock (there's WSLD which uses vsock for a more stable & reliable connection).

wsld can do the same for regular xserver which to me currently looks like best option.

With the Ubuntu 21.04 Community Preview from MS Store (with the ubuntu.Interop.advancedipdetection: true) it's fine but, if that isn't a distro that one would like to use then WSLD helps with that as well. You can see my post here from a while ago for a quick reference too.

Sure, but the experience is pretty rough. It only renders at a single given DPI, so it's bad if you have say, a 4K laptop and 1080p external monitor. And since you have to go over TCP unless you use WSL1 (or some hacks that require admin access), it drops all X11 connections if you suspend/resume in WSL2.

For automatic startup follow the instructions here (setup using Task Scheduler & ~/.profile / ~/.bash_profile / ~/.zlogin).

Install vcxsrv and use X11 forwarding from your Guest to Windows via TCP. If you want this to be really lickety-split or if you do work that messes with your network connection, you can use VSOCK via x11-over-vsock. To get sound working, you can probably install Pulseaudio on windows and connect to your Linux guest that way.
