I was watching this video. How do I get Weston on Ubuntu to try it?
Where can I find other desktop environments that work with wayland - are there any wayland ports for it like GNOME and KDE?
To enable it follow the directions here 18.04: How to get Wayland back after upgrade to 18.04?
On the login screen, you should be able to select "Ubuntu on Wayland" by clicking on the settings icon, next to the login button.
