If I log in on pts/0 with vnc and in the Xterm i give the command startx. 
The X Server start on ttyX and the user that is on the local terminal can 
use the system with no login. If I close the session of VNC the X Server 
on tty stand up. Otherwise if I close the X Session from pts/0 the X 
Server crash.

I don't see the security problem.  How is this different from doing the same 
thing from within an ssh or telnet session?  Can you explain it in more detail 
please?

Thanks.

Closing.  I think that what you are seeing is expected behaviour.
