F17 GNOME 3 dual monitor problem

[Paul Erickson]

I have installed F17 on an A7V8X-X with an Athlon 2500 cpu with 2.5Gb of 
memory with a
Quadro NVS 280 64MB AGP8X video card. Installation went fine and I was 
able to add enough
extensions to GNOME 3 to make it usable, but when I add a second 
monitor, I get a
"GNOME 3 failed to start" starting in fall back mode.  The monitors are 
identical Samsung
SyncMaster 740N's. A web search reveals that others are having problems 
with dual monitors,
but so far I have seen no solutions.

Anyone found a solution for this?

cheers, Paul
