After some research on the net I didn't find any way to have a keyboard output preview for a xfce desktop. It looks like it is possible only using gnome. (see
https://www.linuxquestions.org/questions...ux-930784/).
I would like to have such a preview because I must switch between different keyboards when writing in different languages.
Any idea of what I can do?
With regards
I found the program "florence", a virtual keyboard, very useful. It solved my problem.

Just need to install it for example through synaptic.

I'm not sure if this exatcly what you want but you might try installing "xfce4-xkb-plugin", it allows you to switch between 4 different keyboard layouts. Just type this in your terminal
Code:
$ sudo apt-get install xfce4-xkb-plugin
Once installed right click on the panel, then select add new item and look for it so it sits on the panel. Also, if you prefer a GUI method, install it via synaptic, then add it to the panel.

Hope this helps!
thanks, but I have it already installed. What I needed was a preview of the keys of the keyboard. For example when I change from german to english keyboard the y becomes z etc... so my physical keyboard does not correspond any more to the one used by the software. A preview of the english (or others) keyboard, in order to find where are the keys I am looking for is my aim.
