Nvidia driver 629 on laptop

I downloaded and installed the new Nvidia driver for my laptop. after installation successfully completes, when it goes into X, I have a black screen (like it is sending to TV out or something) So, I modified my XF86Config to include the ConnectedMonitor CRT and still black screen. I can switch to console, but when I switch back, same black screen. Any ideas? The only thing I can think if is the wide-screen resolution of 1200x800. Thanks in advance. B-)
