GUI Applications Launch in Ubuntu but not Gentoo

[peppapig450]

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.
