The easiest way to install NVIDIA GeForce Driver on Debian Linux 8 ( Jessie ) ( for Debian 9 Stretch visit: How to install the latest NVIDIA drivers on Debian 9 Stretch Linux) is to use official contrib and non-free debian repository. First, add the following non-free and contrib repositories to your /etc/apt/sources.list. Therefore, first change the content of your /etc/apt/sources.list file to include contrib and non-free packages eg.:
deb http://ftp.au.debian.org/debian/ jessie main contrib non-free
deb-src http://ftp.au.debian.org/debian/ jessie main contrib non-free
Next, update your repositories:
# apt-get update

Using jigdo downloader is a smarter and greener way of downloading data from the Internet mirrors. In comparison to a regular download where you point your browser or wget command to a single mirror URL, jigdo allows for multiple mirrors where the main feature is to re-use a previously download ISO image of a lower version to use as base and thus only new packages not downloaded previously are downloaded.

For this reason using jigdo is often faster way of downloading debian ISO images. To start using you first need to install it on your system:
# apt-get install jigdo-file
Once the jigdo-file package is downloaded your can start using jigdo do download official Debian instillation images. All you need is the URL of the *.jigdo file of the image you intend to download. In the example below we download Debian Jessie KDE iso image. First start jigdo:
$ jigdo-lite
Jigsaw Download "lite"
