How to setup RHEL 8 to run as a kiosk

While investigate how to setup a PC as a kiosk, I found this blog post describing this RHEL 8 feature. It basically run a minimum Gnome desktop, autologin as the kiosk user and launch the kiosk app. It also disabled the Crtl + Alt + F# key combination to switch to another virtual terminal.

To summarize:

  • Create a dedicated kiosk user
    useradd kioskuser
  • Install the requred packages
    yum install -y gnome-session-kiosk-session gdm firefox
  • Make sure the system start up graphical target
    systemctl set-default graphical.target
  • Setup to autologin as the dedicated user. Edit /etc/gdm/custom.conf. Will also need to make sure Wayland is not running.
  • Setup the user’s session to run com.redhat.Kiosk. Edit /var/lib/AccountService/users/kioskuser.
  • Suppress initial setup dialog box. Edit /etc/xdg/autostart/gnome-initial-setup-first-login.desktop.
    line: "X-GNOME-Autostart-enabled=false"
  • Create an infinite loop script to run the kiosk app by creating file ~kioskuser/.local/bin/redhat-kiosk. In this example, bring up the world clock on firefox.
    while true; do
        firefox -kiosk https://time.gov

    Make sure the script is executable

    chmod +x ~kioskuser/.local/bin/redhat-kiosk
