Thanks for your advice, I was able to spawn an Xvfb for display :1 like
you suggested but apparently, the tests for python-manim want to create
some type of cache folder.  The tests now raise a different error:
`Failed to create //.cache for shader cache (Permission
denied)---disabling.' I have to investigate where this error message
comes from.  I suppose I have to set some environment variable.
Nevertheless, what would be an appriopiate writable location for the
cache?

Alright, thank you.  I will give the other tests another try.

Best Daniel
