Now look at the file output for an xwin display manager starting up via 'S' at the beginning of the filename to start the service. In my case, it was /etc/rc2.d/S17gdm3. In my case, to stop or kill Xwindow at default runlevel 2, I just did this:
cp /etc/rc2.d/S17gdm3 /etc/rc2.d/S17gdm3.bak #safe keeping
mv /etc/rc2.d/S17gdm3 /etc/rc2.d/K17gdm3 # 'K' to kill sevice
reboot
The original idea is also very informative and useful to know.
