Perhaps you could look at how this guy did it:

回答2:
You could start with a minimal linux distribution such as Ubuntu Server and install only X-Windows (without any Window Manager) on top of it: https://help.ubuntu.com/community/ServerGUI
Then, start your Qt application by adding a call to it in the .xinitrc initialization script.

Might be helpfull Linux Journal KDE Kiosk Mode
回答4:
Why not run x server without window manager and the running the application in full screen mode on that x server.
to start x server type startx and then you must run your application in fullscreen mode (your app must support this mode by argument switch like this)
./myapp --fullscreen
回答5:
I have never tried this, but try google for 'framebuffer'. It should allow you to run a single application with no need for X server.
