Pengwin: Penguin GUI apps not working with VcXsrv

[Thorocaine]

Describe the bug
Trying to run a GUI app returns:

Error: Can't open display: :0

To Reproduce

1. run penguin-setup
2. install emacs and VcXsrv
3. use apt to install x11-apps
4. restart computer
5. open terminal, and open wsl (to make sure it is running)
6. from the start menu try open emacs GUI (nothing happens)
7. from the terminal, try run xeyes (get Error: Can't open display: :0)
8. check system tray (VcXsrv is running version 1.20.1.4)

Expected behavior
I expect the programs to run, and not give an error

Hello,

By any chance you are using WSL2? It should work in WSL1 for WSL2 we are working on this.

It is WSL2.
Thank you for the quick update.

Follow this PR: https://github.com/WhitewaterFoundry/pengwin-base/pull/61/files. You'll need to replace your /etc/profile.d/00-pengwin.sh with the file in this PR and be sure that VcxSrv accepts connections from anywhere: vcxsrv -ac

@crramirez That worked as well, thank you, it just needs AC Disabled, I might be able to create a default config.

For anyone who stubles accross this:
After replacing 00-pengwin.sh as per @crramirez you want to edit the file /etc/profile.d/vcxsrv.sh.
you can add -ac to the command that is run from there.
