4. sudo apt install cosmic-session

6. set "WaylandEnable=true"

7. reboot

8. at the log in screen, there is a small gear wheel on the bottom right side, choose “Pop on Wayland" (edit: if you want COSMIC DE to work too, see update below)

• Display Spice : Type = Spice server, Listen type = none, uncheck password / opengl
• Video : use QXL (instead of default Virtio)

The base Ubuntu 24.04 LTS shipping with Linux kernel 6.8 is anticipated for release on April 25th, 2024.
