Switching between 2 video cards

Hi everybody,
I installed 2 vga on my desktop. The first one is a Radeon 5770, the second one is a nVidia 210.
In BIOS settings I selected Radeon as first vga because I have to use it in windows.

I want to use nVidia on linux, so I want to disable Radeon card.
At the moment I can see signal only from 5770, none from nVidia (installed driver from pacman and created xorg.conf file)
Tried to blacklist radeon module adding  modprobe.blacklist to the kernel line in menu.lst file.

What can I do?

Re: Switching between 2 video cards

Partially found the solution.

In BIOS settings -> nvidia 1st vga, radeon 2nd

WIndows: installed nvidia driver, then disabled nvidia vga. Only Radeon, but if I want, I can use physx featurs in videogames.

Arch -> boot from nvidia, as it was the only card! Everything is ok.

Now, the last issue: On arch I want to turn off Radeon vga.... how to?

Thanx!
