I have deployed a kiosk mode system with gnome-kiosk on Ubuntu 24. Kiosk mode in gnome limits user interaction for a self-service computer.

The session is automatically started via GDM, and when the key combination CTRL is pressed, the system will switch to a tty allowing connection with the current user.

Do you have any idea how to block this behaviour and prevent the user from obtaining a tty with this key combination?

Thank you,

Perhaps try the following;

sudo tee -a /etc/init/tty3.override <<<"manual"

If there are other TTYs with such issue, change the 3 to the TTYs number or just follow the solution I've linked above

    I don't know why OP accepted this, but /etc/init hasn't been used since Ubuntu 15.04 when it switched to systemd as the default. Commented Aug 22, 2024 at 13:00
