GNOME3 stopped functioning

[BinaryBandit]

G'day folks,
my friend GOOGLE has not helped me today
I installed a second monitor, when I restarted X there was a brief message about incompatibility, both screens worked as intended but in what appeared to be the old classic gnome desktop (most likely fall back mode for gnome shell).
I tried several things to get it back to normal, including removing the second monitor and returning to default monitor settings, however without any success.
Any help will be appreciated.

Fedora 16
EN 250GTS
C2D E6750
Asus P5G41

Thanks,
The Bandit

Was the second monitor a replacement or supplementary to the first? What do you have attached now and what state is the system in at this point? Is it still fallback gnome or no X server at all?

Thanks for the reply,
The second monitor is a supplement to the first.
When Gnome3 crashed it reverted to 'Fallback mode'
I was able to resolve the issue by replacing the Nouveau driver with the Nvidia driver.
I'm not sure what the issue was with the Nouveau driver, I had successfully run two monitors
on FC15 with Gnome3 and I don't remember having any issues.
I have built a new system since my last post and have installed FC17 on it,
It runs two monitors without any problem using the in built Intel HD4000 graphics.

Cheers,
The Bandit.

I gave up 2 monitors on Gnome 3 since it did absolutely not work when Gnome 3 first came. After that I have tried it in Fedora 16 to with the same result.
Solution : switch to KDE.
Code :
yum install @kde-desktop

Be amazed how good 2 monitors is with KDE.
