Lxde - how to enable X server nolisten ? (Solved)

[whywhy]

My /etc/X11/xinit/xserverrc is as follows :
#!/bin/sh
exec /usr/bin/X -nolisten tcp "$@"

And I am starting my X window using "startx".

In my .xinitrc file I have :
exec ck-launch-session startlxde

However, even though the xserverrc have the nolisten option, my X server is still starting up on Port 6000.

Is there any other file that override the default xserverrc file ?

Thanks in advance.

P.S I found the problem, I have a alias for the command startx like startx=startx -logverbose 6, which somehow override the default.
