Jerry, that's a good suggestion (to try this as "root"). I think
however, I'm going to wait until the weekend and try this with a fresh
install on a separate partition. I'm a little gun shy about reverting
settings for a third time.
Thanks for the good tips!

Most of these settings are stored in "hidden" files in your home
directory.
An 'ls -al' will show you all your files, hidden or otherwise as well as
the permissions.
Once you determine that these files may have incorrect ownership, then:
'sudo chown -R <you>:<your group> .'
Should set everything back to the correct ownership.

1., become root using sudo ' sudo -s -H'
2. cd /tmp.
3. Check permissions and ownership of files in /tmp
4. reinstall the nvidia driver. Something like 'apt-get install
--reinstall nvidia'
After reinstalling, check the permissions and ownership in the /tmp
directory.
5. Restart X by logging out, and logging back in. Your home directory
should be untouched, and it any file permission has changed in /tmp,
then the nvidia package is suspect.

Thanks for the tips guys! I tried to recreate the problem and ran
into a couple of new ones, lol...
(1) I couldn't figure out how to switch to the Gallium driver. After
searching online to no avail, I tried switching the "Driver" line in
xorg.conf to "gallium." That didn't seem to work. When I logged back
in, the display was super low resolution and listed the driver as i915.
(2) I figured that removing the package for the nvidia driver would
switch me back to Gallium. It didn't.
(3) I reinstalled the nvidia driver. Nowhere along the way did it
change the permissions on my home directory. However...
(4) When I got back into Cinnamon, I lost settings that you wouldn't
expect I would have lost. For example:
a- My language setting was lost
b- My panel settings were back to the default
c- My window settings (e.g. where the maximize/minimize/close buttons
appear) were back to the default
d- I had my GMail account configured in Pidgin for GTalk and the
account was gone.
e- Also, in Pidgin, I had disabled the lib-notify plug-in. It was
re-enabled.
f- When I started Firefox, it checked for plug-in compatability,
which it only does the first time you run it after installing a new
version, so it seems to have forgotten it had already done this
g- In Terminal, I had changed the colors. These went back to the
defaults.
h- When I look at my bash history, I don't see any of the apt-get
commands I used for this experiment or the editing of the xorg.conf
file, which leads me to believe I may be going crazy.
I'm guessing some or all of the above settings were all stored in my
home directory. So like I said, I couldn't recreate the original
problem, but I managed to create some new ones.

You could follow Bill's suggestion and pull apart the package and see
what it does. Or you could just test it... Being very careful not to
run anything else, log in to your system, change the driver back to
gallium. Log out, and check your ownership and permissions. Then log
in again, update it to nvidia again, and do your check again.
Possibly an easier way is to make sure everything is Kosher including
your home directory permissions and ownership, then after you have
verified, reinstall the package that you think caused the problems,
then
double check the ownership et. al. Then you can terminate your X
session
by logging out. You should be able to log in once again. Or if the
problem is the same as before, then you can assume that the package you
installed is the culprit.
Possibly easier, or possibly harder. It's almost exactly what I
suggested, except it leaves out the step of returning the machine to
the state it was in prior to upgrading the driver. If the problem is
caused by an interaction between those two, skipping that step will
obviously not trigger it...
