Please check that the $DISPLAY environment variable is properly set.

I'm on openSUSE Leap 15.3. I've set up everything else necessary to run WinApps, this just seems to be the thing blocking me from finishing.

Executing `sudo bin/winapps check` results in error:


What am I supposed to set the DISPLAY environment variable to? I can't find that out from searching the internet. Any help is appreciated.

Reproduce the reported failure on openSUSE Leap 15.3 by running `sudo bin/winapps check`. Start at the `bin/winapps` check entry point and trace how it reads or validates DISPLAY. Done means the check either succeeds with the correct environment or clearly explains what DISPLAY value is required.
