[BUG] xhost unable to open display (+ fix)

[XVanilor]

Initially, I wrote this bug report to provide troubleshooting to anyone which might encounter it, as Exegol does not indicate what could have gone wrong. It would be great to raise a message to indicate what's missing (DISPLAY environment variable on the host) instead of the default error message of xhost

Hello

Thank you for the feedback

The wrapper already uses a fallback to ":0" if the environment variable is not present. (See the last line of execution in the section "Execution logs in debug mode") but this is only applicable inside the container, we don't change the host environment configuration.
The wrapper tries to call xhost but indeed if the host is not correctly configured it will cause problems.

The problem being rather on the side of the host (/ DISPLAY service) I don't see what to add on the wrapper side...

Maybe add a warning message if the xhost commands fail ?
Or maybe add this use case in the documentation for troubleshooting ?
What do you think @ShutdownRepo ?

Agreed, this is a host issue.
However, we could probably raise a warning message at wrapper level if we feel like the DISPLAY env is messed up and user didn't use --disable-X11

[ShutdownRepo]

Agreed, we'll make the necessary changes to the wrapper
Thank you for raising the suggestion
