Hello Marco,
Nice to hear you!

I saw that Xorg start correctly, then it try to launch xterm, but since this is not present in our system, it exit and close up everything.
I just replaced the execution of xterm with the execution of my application, and it works perfectly. I also know that by default Xorg stay alive until the last client application is not closed, but I would prefer to launch Xorg without clients, and then be able to start and close what I want without need to re-launch Xorg.

But I don't know how to do it...

Thank you

>> What I would obtain, is to launch Xorg once at start, and then work freely opening/closing my application, which should connect and disconnect to/from the already active Xorg server.
