Here's what I did to login to X:

1.  I added the following line to /etc/inittab.  Rather than running
    hpterm directly, I run a script that does a few other things as well.

	X0  : 2 :respawn:env PATH=/usr/bin/X11:/bin:/usr/bin xinit \
			/users/cary/bin/xstart.init ttyqf \
			-- :0 >>/tmp/xinit.log 2>&1

2.  I linked the ttyqf and ptyqf device files from the /dev/pty and
    /dev/ptym directories into /dev, because older hpterms couldn't
    find them otherwise:

	ln /dev/pty*/*qf /dev

    (I picked ttyqf arbitrarily.)

3.  I added the following line to /etc/gettydefs.  When hpterm runs
    getty, it uses an argument of "Xwindow".

	Xwindow# B9600 HUPCL PARENB CS7 # B9600 SANE PARENB CS7 ISTRIP IXANY TAB3 #X login: #9600

4.  The script /users/cary/bin/xstart.init starts up the clock and
    login window, and also loads my X defaults and sets the root
    window pattern:

	MYHOME=/users/cary

	: ${DISPLAY:=unix:0.0}; export DISPLAY
	TZ=PST8PDT
	export TZ

	xset b 60 880 100 s 1200
	xrdb -load $MYHOME/.X11defaults
	xsetroot -bg SeaGreen -fg Grey -mod 16 16
	xclock -geometry 128x128+10+10 &
	exec hpterm =80x24+10-10 -L "$@"

    The final argument to hpterm comes from the inittab line ("ttyqf").

5.  In my .profile, I test the tty to start up the rest of my clients.

	if [ `tty` = "/dev/ttyqf" ]
	then PATH=$HOME/X11/bin:/usr/local/bin/X11:/usr/contrib/X11Programs:/usr/bin/X11:$PATH
	     export PATH

	     : ${DISPLAY:=unix:0.0}
	     export DISPLAY

	     xsetup
	fi

Be careful!  When you logout of the initial login window, X will terminate
(and all the clients along with it), then init will respawn the whole
thing.  This sure makes it easy to shut down at the end of the day,
though.

If you want to login on the console without running X, you'll need to
change the run level to 1 (type "init 1" as root).  I considered setting
up the X stuff as run-level 3, and making that the default, but it hasn't
yet seemed necessary.
