Im running a labwc kiosk app and want to prevent users from tty switching easily.

Previously, I had a Xserver with the "DontVTSwitch" option on and it worked like a charm. I changed to labwc because external things and I'm having a ton a difficulty implementing this. There are some requirements:

  • Prevent exiting labwc view with Ctrl+Alt+F[2-9]
  • Allow to switch with a special keybind (this is already implemented using a keybind in .config/labwc/rc.xml that calls a script that uses chvt)

Some things I've tried that did not work:

  • Creating empty keybinds in .config/labwc/rc.xml like this <keybind key="C-A-F2"><action name="None"/></keybind>
    • It did not work. I think the keybind does not reach this part. i tried change to <action name="Execute" command="echo 'VT switching'"/> and it did not print and still changed.
  • Change NAutoVTs in /etc/systemd/logind.conf to 1
    • It did not prevent from exiting the labwc view but it did not appear the login prompt
  • Delete any line that contains 'Console_' in dumpkeys and then loading this new map
    • It worked in reverse. I can exit labwc with the command but I cannot get back
