Warning, this is a long message!

I'm having a slight problem trying to boot directly into X.  When I boot to
a console, login, and run "startx" everything seems fine.  However, when I
modify my rc.local file to startup X directly, it seems to start, displays
the default background and the "X" cursor, and then justs sits there.  No
menus, no login window, nothing.

After about 60 seconds (rought estimate) it returns to a blank console
screen for about 10-15 seconds, then returns to the blank X display.

While in the console display, either CTRL-Z, CTRL-X, or CTRL-D breaks the
cycle and brings up a login: prompt.

Any ideas?

Here are some relevant snippets of various files (though my determination
of relevant may be entirely off-base):

/etc/rc.local:
--------------
if [ -d /usr/X11R6/lib ]; then
echo 'adding X11R6 sharable libraries to cache'
ldconfig /usr/X11R6/lib
#
# Start up the X login if xdm has been configured
# NOTE: we only do this if we loaded the X sharable libraries
#
#if [ -f /usr/X11R6/lib/X11/xdm/xdm-config ]; then
#	/usr/X11R6/bin/xdm -server ":O Mac-terminal local /usr/X11R6/bin/X
:O" &
#fi
fi

/usr/X11R6/lib/X11/xdm/Xstartup:
--------------------------------
#!/bin/sh
#
# Update the utmp file so we know who is currently running on the display.
#
sessreg -a -I $DISPLAY -x /usr/X11R6/lib/X11/xdm/Xservers $USER
exit 0

/usr/X11R6/lib/X11/xdm/xdm-config:
----------------------------------

Are there any other files you need to see, or anything obvious that I am
missing in the setup here?
