I did not tested yet in Wayland, but Calamares 3.2 series was supposed to support Wayland too: https://calamares.io/calamares-3.2-plan/ https://github.com/calamares/calamares/issues/747#issuecomment-309212388 https://www.debian.org/News/2019/20190706 - debian by default is with Wayland and live images includes Wayland.
