KDE Plasma and virtual keyboard don't work in live boot session

[newuser0001]

Hello guys,

I just tried Kubuntu 25.10 Questing Quokka on my Dell Latitude 7320 Detachable in a live boot session using a boot stick.

However, I think it fails to load KDE Plasma when I choose it as a desktop environment on the login screen. After logging in with Plasma(Wayland) set as an option, I still see the Kubuntu desktop, not Plasma. I'm not very experienced but I tell it from the Kubuntu startmenu icon which still shows up in the bottom left corner instead of the KDE Plasma icon.


Also the virtual keyboard doesn't work. When I click it in the login screen, nothing is showing. In the system setttings, there is only the option "none" to choose.

I currently still have Windows 11 installed, but I don't yet want to remove it, since I only want to keep this PC if I find a Linux OS which I can use it well with as a surface PC in tablet mode.

Do you have an idea what could be the problem here and how to fix it?

Kubuntu is the OS, and it uses the Plasma Desktop environment, so you are in Plasma

The keyboard, I am not sure, it at least partly sucks, and to get it at the login screen might take some fiddling around.

Orrrrrrr....just look at this post for the fix.

And you also need to install a desktop keyboard, the qt-virtual one does not work on the desktop, So iirc you still need to install maliit-keyboard and enable it in settings.

It works, but may not work in every application.
