Keyboard switching not working in MATE

There is no flag or indicator in the empty space of the tray where the indicator lives.
No key combination works. Tried all sorts of Ctrl-Shift, Alt-Shift, Ctrl-Alt, Win-Space, Win-Shift/Ctrl/Alt whatever. Tried to cliick the indicator. Tried to right-click and use the pop-up menu. Even if alternative layouts are chosen, the input remains the default. Moving the alternative layout to the top does not help. Dead in the water.
This is a F41 VM in WS HyperV. We can’t go 42 because it does not have the software which we require, so stuck on F41.
Out of desperation, we wanted to try KDE, which the user does not like, so we went to Switching desktop environments :: Fedora Docs and followed the installation steps for KDE and the desktop switcher.

# dnf history list
ID Command line                                                Date and time       Action(s) Altered
 7 dnf install switchdesk switchdesk-gui                       2025-11-19 13:16:32                 2
 6 dnf install @kde-desktop-environment --allowerasing         2025-11-19 13:13:32               400

After both were installed, and the VM rebooted, there is no KDE in the switcher tool:


The KDE is still listed as available:

# dnf environment list --available | grep desktop
Updating and loading repositories:
Repositories loaded.
kde-desktop-environment           KDE Plasma Workspaces                       no

When we look at the DM login screen, there is Plasma in the list, but it is not clear how to choose it because we log in through XRDP which takes us to MATE regardless.
I read that using this command, I should be able to switch the DM:

update-alternatives --config x-session-manager

However when I run it, there is no menu to choose from. It simply exits right away.

EDIT: Does it matter that the language selector shows a duplicate of every language? Is this the expected behavior? Did anyone test this before it was included in the Fedora OS releases?

You are playing with very old software. Inkl. Mate desktop which not updated the desktop since almost two years.
As in the article above mentioned, normally you can switch the desktop on the login screen with newer DM’s.

Fedora is moving ahead with Wayland etc. and the Mate desktop is standing still since a while. How and what should we test here. A Spin is at it comes from upstream. They not block an upgrade, so they are like in a Standby mode, till someone figures out how it works, and maybe posts a workaround.

p.s.
Please read the topic I linked, to understand the problematic you are facing here.

We are not playing. For us, it is not a game. Insult noted.

It is not an insult when I say you use outdated software. Wen you want to help them then you can do this upstream.

And the Fedora Version you are using is in the next few days EOL too.
