This question already has an answer here:

I have a project that requires a Debian device to run one simple custom app on a touchscreen from boot to death. It shouldn't be possible to exit the app.

I've looked into Gnome, KDE, XFCE, and Tcl/Tk, but it's hard to tell which are the best for a single app rather than an entire desktop. What are the best options out there?

Bonus points if the solution is in any way easy to program and/or better than average on security.

  • Doesn't matter which you pick, as long as it can run in fullscreen without expecting a WM to exist. – Ignacio Vazquez-Abrams Dec 4 '17 at 18:36
