Any suggestions??


Did you check port 6000?
root@pc6:~# netstat -anp | grep 6000
tcp   0   0 0.0.0.0:6000   0.0.0.0:*   LISTEN   2684/Xorg
tcp6  0   0 :::6000    :::*    LISTEN   2684/Xorg


Bingo! The command gave me empty output.


Always start low level.

Now -nolisten tcp is the 
default Xorg behaviour. Thus, you need to add -listen tcp flag 
explicitly.


That changed some time ago.


I added:
arg=/usr/bin/X -background vt07 -listen tcp
to /etc/lxdm/lxdm.conf and now it works perfectly.


Sometimes it's in /etc/X11/xdm/Xservers or /etc/X11/xinit/xserverrc
With lightdm it's in /etc/lightdm/lightdm.conf;
xserver-allow-tcp=true


Regards,
Rob
