I hadn't known of zap.  Indeed it's an easier way to do the cleanup.
However, use it _after_ stop.  

I tried it instead of stop.  What it does is remove the 
/var/init.d/*/xdm files.  With them gone,  "/etc/init.d/xdm status"
can't tell that xdm has been started and "/etc/init.d/xdm stop" doesn't
do anything.  I had to frog around to fix the problem.

Be careful !!
