Consider mutter instead of Xvfb #6

Closed mickaelistria closed 1 year ago

mickaelistria commented 1 year ago

I'm currently using the xvfb-action in some workflows. I'd like to get rid of Xvfb and to use headless mutter instead, which is available since Gnome 40: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1698 Would it make sense for this action?

I'm not well versed in the differences/motivation but I'm open to reviewing a PR with the change.

My main concern is that there are a lot of downstream repos using this action and are using xvfb-run in their workflows.

Honestly, I'm hoping we (being PyVista projects) can move away from this whole action now that we are building VTK wheels with different graphics backends; eliminating the need for a virtual frame buffer altogether.

This is further motivated by how we've been unable to update OSMesa on Windows.

OK, it looks like this is not really in the scope of this project. I'm going to close it. In the meantime, I found this simple build step allows to replace Xvfb by mutter in my workflows, without having to adapt other steps
