Answer 2

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.

Answer 3

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

Answer 4

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.
