Solve Macbook pro 7.1 VGA NVIDIA black screen, not detected, external display doesn't work in Ubuntu

There are a lot tutorial to installing NVIDIA Driver in Macbook Pro 7.1 on Ubuntu. But, I ended up with bad result.
What I facing before, I got blank screen after installing Nvidia current-driver. Also, my dual monitor doesn't works (I use DELL monitor).
What actually happen is my Nvidia doesn't detected in Ubuntu and there no additional new device (jockey) for this VGA.

Finally, I made my Nvidia in Macbook Pro 7.1 working 100% in Ubuntu 11.10 Oneiric.
So, how to solve this problem and make it works?

Basically, it's pretty easy :

1. Blacklist nouveau driver
Open "/etc/modprobe.d/blacklist.conf" and add this into bottom line :

2. Install Nvidia current driver
sudo apt-get install nvidia-current

3. Edit GRUB
Add "nopat" in GRUB_CMDLINE_LINUX.

Then update grub by :

4. Reboot and enjoy your VGA!
