If you expect to run clients from foreign machines, you should make sure
this line appears in /etc/services:

	xserver0	6000/tcp

otherwise the X server will silently ignore all network client
attaches.

To run OpenLook on System V Release 4.0 you should run ``oladduser'';
by:

	# cd /usr/X/adm			# (or maybe it is /usr/lib/X/adm)
	# ./oladduser USERNAME

``oladduser'' sets up all the necessary OpenLook init files and
patches your .profile to start them up.  The last release of oladduser
from AT&T did not come with the necessary intelligence to deal with
csh, so you should have USERNAME's login shell be `sh' or `ksh'.  Now
login as USERNAME and type:

	$ olinit

This should start up OpenLook.

If you are still having problems, try this:

login as guest and type:

	$ X

login as guest again on the same machine (either by using the multiple
console thingies or telnet in from another host or whatnot) and:

	[ Make sure you are in bourne shell ]

	$ DISPLAY=unix:0 ; export DISPLAY
	$ cd /usr/bin/X11
	$ ./xterm
