Single Application Mode on Ubuntu/RedHAt

Desktop

I am trying to build a linux box that work as a kiosk in a single-Application Mode. I found a guide here

https://help.gnome.org/admin/system-admin-guide/stable/lockdown-single-app-mode.html.en

but i’m not able to make it works.

My main doubs is the steps 6:

*Define the kiosk session by writing a custom session definition, containing the following line:*

*RequiredComponents=kiosk-app;gnome-settings-daemon;kiosk-shell;*

I imagine if i want to run google-earth my required component will become:

RequiredComponents=google-earth-pro;gnome-settings-daemon;kiosk-shell;

but where do i have to put this line?

here --> /var/lib/AccountsService/users/kiosk-user?

and about the step 8:

create a mode definition /usr/share/gnome-shell/modes/kiosk.json

What i have to put in this file if i want only google earth available?

In /usr/local/share/gnome-session/sessions/my-kiosk.session

You can’t restrict individual applications on that level. What you probably want in a kiosk setup is disable the activities overview. /usr/share/gnome-shell/modes/initial-setup.json is probably a good appromixation of what you’d want in a kiosk setup.
