Syslog is
reporting Compiz Segfaults, with compiz.desktop respawning too
 After the Coloured Background appears, that is wiped clean leaving a
"Blank" Screen...  Very occasionally a Compiz Error pops up, although
disappears before I have time to read or interact with it...

Graphics Card is an NVIDIA GeForce 6200 and I had the same "Problem"
either of the currently available NVIDIA Drivers installed...

Any IDEAs what is going "Wrong"???

Have you run computer janitor yet to clean up after the upgrade? Ric

Just ran Computer Janitor, but I still can NOT run Unity in the 3D Mode.

Try, in a terminal running
unity --reset
and log out and in again.
This should reset compiz settings which may help.  If still no joy see
what happens if you login as a different user.  That may indicate
whether it is a system wide problem or a problem with the users

Running "unity --reset" from a Terminal still does NOT allow me to run Unity
in its 3D Mode...  I had already tried creating a "New" Account to see if
there might have been some settings hanging around from when I last ran
Unity 3D under Ubuntu 11.10, although there was NO "Difference"...

No need to shout, we are only trying to help. Have a look in syslog
to see if there are any messages (use the Log File Viewer). Note the
time at which you attempt to login so you can find the right bit of
the file. If there are any error messages search on launchpad to see
if it is a known bug.
