How to get a Wayland session in Kubuntu?

Ubuntu 17.04 comes with a wayland display server session. I've used and seen what it can do, I've used it before by selecting it from the lock screen just like selecting Unity 8 session, with a gear icon, that option doesn't appear in Kubuntu's lock screen. A blatant explanation would be that Kubuntu doesn't ship with wayland display server but it comes with an app exclusively called as wayland

The app itself does nothing that or I can't seem to understand how to use it and make wayland session possible

Update

I'm sure that I'm not running Wayland, but I've seen videos of KDE Neon running Wayland, is it just not possible in Kubuntu?

Solution 1:

Since 5.4 it is possible to start a complete Plasma session on Wayland. For this go to a tty, log in, end the running X server (otherwise startup might block) and run the following command:

startplasmacompositor

Support for running a full Plasma session on Wayland is still in it's early stages. Bugs are to be expected and there are known missing features. Please consider it only as a mode to experiment with.

On Kubuntu you might need to Install plasma-workspace-wayland

sudo apt install plasma-workspace-wayland

Solution 2:

At least as of Kubuntu 17.10, you don't need to do much manual work. First make sure that Wayland integration is installed:

sudo apt install plasma-workspace-wayland

Now you should have a session menu in the lower-left corner of the login screen (SDDM). Select "Plasma (Wayland)" there and you are done. Mind you, Wayland integration definitely isn't ideal at this point. But HiDPI support for example is way better.
