I would like to test different layouts on my keyboard using a GUI, and I would preferably want to use the keyboard layout GUI that is shown during the installation of any Ubuntu-based distribution, because I found it to be very user-friendly.
This is the keyboard layout GUI that I'm referring to:
Is it possible to execute this application without having to follow the installation process?
Are there any other GUI-based alternatives for testing different keyboard layouts?
I am running Xubuntu 16.04.2 LTS
