Activate Nvidia Accelerated Graphic Drivers (Ubuntu 11.10)

I'm a noob in linux, and here's what I got.

Instead of downloading and installing the driver manually from Nvidia you should either use the xorg-edgers or xswat ppa for updated drivers.
https://launchpad.net/~xorg-edgers/+archive/ppa
https://launchpad.net/~ubuntu-x-swat/+archive/x-updates
ATM xorg-edgers breaks Unity in 11.10 so I would suggest x-swat as a small stable option.

What I did, I just copy this codes ;

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get upgrade

and then I'll get NVDIA XSERVER SETTINGS (system>administration).

Configure. DONE.
