[System] Kubuntu 25.04 online says I can add native x11 but I get error

[Gazzer]

Hi,

I have read in this article that I can install x11

You can install an X11 session in Kubuntu 25.10 easily: just run sudo apt install plasma-session-x11

Link ... https://www.omgubuntu.co.uk/2025/06/...ps-x11-session

When i add the text into terminal i get error unable to locate package ?
I do want to use x11 wayland as it's not exactly the same as the original x11 I have been using for many years

Help me if there is anyway I can install x11 ?

Thanks

X11 session in Kubuntu25.10

You are a bit early

25.04 already has all the parts installed. This new package for the upcoming release just depends on these to pull them all in, since they won't be included by default starting with 25.10.

To double-check, just check that you have the package kwin-x11 installed. You should, as it is a default part of the ISO.

All you need to do is select the desired session at your SDDM login screen, down in the bottom left corner.
