Chapter 20. Restricting the session to a single application

Procedure

1. Install the gnome-session-kiosk-session package:

   # yum install gnome-session-kiosk-session

2. As the user that will open the single-application session, create the /home/user/.local/bin/redhat-kiosk file:

   [user]$ mkdir -p ~/.local/bin
   
   [user]$ touch ~/.local/bin/redhat-kiosk

3. Edit the /home/user/.local/bin/redhat-kiosk file and enter the executable name of the application that you want to launch in single-application mode.

   For example, to launch the Firefox browser in single-application mode, enter the following content:

   #!/bin/sh
   
   while true; do
       firefox --kiosk https://example.org
   done

   The while true loop ensures that the application restarts if it terminates for any reason.

4. Make the file executable:

   [user]$ chmod +x ~/.local/bin/redhat-kiosk

5. If you created the file or its containing directories as a different user than the single-application user, such as root, ensure that the file has the correct permissions:

   # chown -R user:group ~user/.local

6. At the GNOME login screen, select the Kiosk session from the gear button menu and log in as the single-application user.
