GUI Applications Launch in Ubuntu but not Gentoo

[Nick]

Windows build number:

Windows 11 Insider Build 26040

Your Distribution version:

Gentoo

Your WSL versions:

WSL version: 2.2.3.0
Kernel version: 5.15.153.1-2
WSLg version: 1.0.61
MSRDC version: 1.2.5326
Direct3D version: 1.611.1-81528511
DXCore version: 10.0.26091.1-240325-1447.ge-release
Windows version: 10.0.26040.1000

Steps to reproduce:

Run any GUI application on Gentoo and you get
Error: Can't open display: :0

The same thing works perfectly on Ubuntu.

WSL logs:

stderr.log
weston.log

I can provide the log files for the working Ubuntu too.

WSL dumps:

No response

Expected behavior:

Actual behavior:

I had issues logging into the Gentoo vm and getting systemd to work with the user account and I bypassed this by logging in like this

wsl -u root doas -u nick /bin/bash

and then running doas systemctl restart user@1000 , maybe it is somehow related to this ?

Also worth noting that the X0 socket in /tmp is not being generated as well

On a whim I installed sway to draw in xwayland as a dependency and it fixed the problem.
Maybe add a note that in order for wslg to work xwayland must be installed on the distro.

It turns out that wayland apps like sway are able to run just fine, but X11 apps are not still throwing the cannot display error.

I knew it was a systemd thing but I wasn't sure what. Thank you, I'll try that when I get home

@viruscamp it worked like a charm, thank you! No idea why it suddenly stopped working in the first place.
