Well, I think I may have found the problem but can't seem to find a 
fix to test my theory.  Xorg is loading Xinerama and I've found some 
noise via google that there is a 'nvidia-xinerama' that is faster 
than the native 'xorg-xinerama'.  I've tried disabling xinerama in my 
Xorg conf file but it loads anyways.

Attached is my xorg.log
