Ubuntu 11.04 x64 - GTS450 as second card Install Fail

Hello everybody,
I am new to the forum, I’ve had some experiences with CUDA, and am looking for help installing a new computer in the CUDA environment of college.

The computer I’m using is an Intel Core i5 with a ZOGIS GTS450.

I am using the onboard video output to the screen and let the Geforce 450 just to do the processing.

When I install the driver I get a lot of mistakes.

Follow the link to the tutorial I’m following:

If someone can help me be grateful.

Thanks
Gabriel.
