Connection refused while initiating application

Hi @nbdd0121, I am having issues with running Terminator GUI via WSL2 Ubuntu.

Here is my setup:

1. Start VcXSrv on windows host with vcxsrv.exe :0 -ac -terminate -lesspointer -multiwindow -clipboard -wgl -dpi auto
2. Start the wsldhost --daemon with in Windows CMD as admin, and verified that it is running on the port 6000
3. Inside WSL via windows CMD export DISPLAY=:0 and start wsld process in background.
4. But I can't get any response for xset q, it just waits.
5. And also when initiating the application I get the following error:

C:\>wsl.exe bash -c "DISPLAY=:0 terminator"
Unable to init server: Could not connect: Connection refused
Unable to init server: Could not connect: Connection refused
You need to run terminator in an X environment. Make sure $DISPLAY is properly set

I can see the correct PID in /tmp/.X0-lock for the wsld process I started. And the /tmp/.X11-unix/X0 also have correct permissions(777):

Thanks!

Start by reproducing the reported WSL2 setup with VcXSrv, wsldhost, wsld, DISPLAY=:0, and xset q, then compare it with launching terminator. Investigate why the X11 connection is refused despite /tmp/.X0-lock and /tmp/.X11-unix/X0 being present; done means the connection responds and Terminator starts successfully.
