This gives me a command prompt on screen 2 on the thin client, but doesn't
permit login by anyone

Yes, it was necessary to use passwd to assign root a
password in the chroot, and then rebuild the image.

Now, on the thin client, I can switch to screen 2 and login to
the thin client as root.

At this point, I can run a command line session. From the thin client,
I can login
to the server via ssh. But if I try to ssh from the server to the
client, I get the message

ssh: connect to host port 22: Connection refused


After logging in as root on the thin client, I can type

X -query :1

And get the graphic GDM user chooser, which lets me login as any
user and run a full GNOME session on the server which displays
on the thin client.

This would almost be satisfactory if I could tunnel through ssh, but
of course, sound and local devices USB devices won't work this way.
But as Barry said in a previous, I must be very very close to getting
LTSP to work.

I checked. This file does not exist on the thin client.
The thin client does have an /etc/ssh/ssh_known_hosts file.

I'm not familiar with compiz, but a quick Google search indicates that
it looks like some sort of 3D rendering environment. How do I know
if compiz is enabled, and if so, how would I disable it?
