Xwrapper is a small helper program whose only purpose is to give the X
server the needed privileges to access the video hardware. Thus, Xwrapper is
SUID root. It sets up the privileges then hands off control to the main X
server program, which is not SUID. Xwrapper executes /etc/X11/X to start the
X server.
So, the sequence is:
/usr/X11/bin/X -> /usr/X11/bin/Xwrapper -> /etc/X11/X -> /usr/X11/bin/XF86_*
If you try to run your X server directly as a regular user, you will get a
message like this:

I hope that clears everything right up. ;-)
