How does it work?
Wayback is essentially a stub Wayland compositor which sits in front of Xwayland. It implements only what is needed for a rootful Xwayland to run, essentially acting as a full X server backed by Wayland. This allows using X11-only desktop environments and window managers under a Wayland base.
What's the current status?
Wayback is still in an experimental state. A lot of work needs to be done currently, but it is already daily-driveable by users with basic setups and requirements, although expect breaking changes and bugs. You can help us make Wayback stable by reporting and fixing bugs you encounter.
Community
The Wayback community is centered around the freedesktop.org GitLab page and meets in the #wayback IRC channel on Libera.Chat which you can join from either the web client Libera.Chat offers, your favourite IRC client, or #wayback:catircservices.org on Matrix. Channel archives are available on catirclogs.org. We also have a Code of Conduct.
