checking to see if wayland is installed

[666JTK666]

my system is running PLASMA X11 and i want to switch to wayland, but i dont seem to have that option. rebooting the xomputer to the login screen there is no little gear icon to switch between x11 and wayland.
So i would like to check and see if wayland is installed and if not get it installed.
As a side quetion how do i upgrade to 26.04 wayland is the default on the newest release.
X11 has been working fine but there is a piece of linux software that will only run on wayland that i would like to use.

thank you in advance for your help and suggestions.

What is it?

You need to add a login session option to your login, which can be done by installing plasma-workspace-wayland

But a caveat -- Wayland in Plasma 5 is not mature in many areas, compared to to Plasma 6. It may even be quite terrible, especially on Nvidias graphics.

What claydoh says.

As for system info, it's a bit of an overkill, but run this command in Konsole:
inxi -Fxxx
Then study the output. Probably under Graphics > Display.

the software is called breezy-desktop

it's software to use AR/XR glasses.

I am not sure how to install "plasma-workspace-wayland"
is it sudo apt install plasma-workspace-wayland ?

is it sudo apt install plasma-workspace-wayland

Correct.
You can also use a GUI package management tool called Syanptic if you want. You can find it in Discover,
