I may have to take back my previous posting, since I agree with Lucio that 
with NVidia's Proprietary Driver removed, compiz runs without Segfaults 
and I see no signs of unity-2d-panel or unity-2d-shell running.  That said 
I am not sure whether Unity is actually running in its 3D Mode???  I also 
tried a "Clean" Installation of Ubuntu 12.04, where NVidia's Proprietary 
Driver was pre-installed and therefore had to be removed before selecting 
"Ubuntu" at the Login Screen would give a "Workable" Console...

NOTE: Following the removal of NVidia's Proprietary Driver, the screen
       display itself returned to what I consider to be "Normal"
       (Full-Screen, ie. no frame around the desktop and without an
       annoying "Flicker", indication of a poor choice of Refresh Rate)...
