Pytest fails with Segmentation fault on headless session

[alexandrevicenzi]

We are happy to answer your questions about the code or discuss technical ideas.

Please complete the following checklist (by adding [x]):

• I have searched open and closed issues for duplicates
• This isn't a feature request
• This is not a report about my app not working as expected

The tests fail to run if the session has no desktop environment, for example, over SSH or while building an RPM. On a graphical environment, I see that tests open windows.

Ideally, tests should be skipped if there's no desktop, it might be easier than rewriting tests to not require a desktop env.

Hey @alexandrevicenzi thanks for raising this. We actually configure this within our docker images as we basically emulate a desktop. I'll comeback at this tomorrow with the code example of what we're doing.
