I'd say it's because you're not running it under /dev/tty1
(/dev/console), my fix consists of a small script that's executed in
rc.local that puts up a prompt *before* /etc/rc is over, and if the
user hits RETURN, it will start XDM. If nothing happens (ie, the user
doesn't hit RETURN) for 5 seconds, it simply skips XDM.
In fact, the script can be more generally used to get a "smarter"
behaviour without blocking the machine:
# ask "Question" | read ANSWER
will set ANSWER to either START or SKIP depending on whether the user
hit RETURN or the timeout period (default 5 seconds) expired.
Note that this requires /bin/sleep to exist, which it "normally"
doesn't, just make a copy of /usr/bin/sleep (so it can be used before
/usr is mounted).
Caveat: the stuff that follows is my /etc/rc{,.local,xdm} and
/etc/inittab. Do *NOT* blindly copy them over to /etc or you may
regret it.
enjoy,
