Sounds right.

no to yes.
(6) I looked at /etc/default/keyboard again and noted there now was

This is expected after doing dpkg-reconfigure keyboard-configuration.
(5) I tried ctrl-alt-del and ctrl-alt-backspace again (without

This will not work. Please see below.

At last! Udev does not know about what you have done, so one way of
beating it into submission is by rebooting. A gentler approach is
udevadm trigger --subsystem-match=input --action=change
So *somewhere* in the cruft on the old system was *something* that
interfered with restarting the X server. But I don't have the
energy to track it down. It will just have to remain one of life's
little mysteries.
Sorry for all the fuss...
It's not a fuss but an interesting situation. Nowadays, most users would
not know of ctrl-alt-backspace as a way of exiting X. The DEs have seen
to that. But, for the present, it can still be used if you know how to
activate it, as you have discovered.
You asked about ctrl-alt-del (or some other key combination) to close X.
Please look at /usr/share/X11/xkb/symbols/terminate:
partial default modifier_keys
xkb_symbols ctrl_alt_bksp {
key BKSP {
type=CTRL+ALT,
symbols[Group1] = [ NoSymbol, NoSymbol, NoSymbol, NoSymbol,
Terminate_Server ]
};
};
Changing 'key' to 'DELE' might be a thought. Except . . .

I usually activate ctrl-alt-bksp during the post-installation phase
when I install/purge/configure stuff I want/don't-want that differs
from the default installation. Some of that requires a reboot anyway,
so using udevadm isn't necessary (Don't force it -- use a hammer!)
though thanks very much for the pointer. It's clear I've got a lot to
learn about this area.
I'm perfectly happy with ctrl-alt-bksp -- I just want *some* one key
combination I can remember to use for that purpose.
Discovering that ctrl-alt-del started the screensaver was fun. It
will be useful!
Is /usr/share/X11/xkb/symbols a good place to look for other
interesting key combos?
Thanks to everyone for all the help!

Anybody know what I'm missing? Thanks! Rick What you're missing is a text file in /etc/X11/xorg.conf.d which is needed to make the ctrl-alt-bkspc combo work since in recent Xservers the 'DontZap' option has been deprecated.
