We have an increasing number of questions from our Linux community about using Wayland. Our take is that Wayland remains an experimental, evolving idea. It is still missing basic functionality that KiCad users have come to expect. We hope that it continues to improve. But for now, if you need to use KiCad on Linux, we recommend installing X11.
