Before installing Nvidia drivers make sure you have the latest Debian version by running:
sudo apt-get update
sudo apt-get dist-upgrade
then reboot your computer

lspci -nn | egrep -i “3d|display|vga”

sudo nano /etc/apt/sources.list
(main contrib non-free)

sudo apt-get update

sudo apt-get install linux-headers-$(uname -r|sed ‘s,[^-]*-[^-]*-,,’)

sudo apt-get install nvidia-settings nvidia-driver nvidia-opencl-common
or (for hybrid graphics chipset):
sudo dpkg –add-architecture i386 && sudo apt-get update && sudo apt-get install bumblebee-nvidia primus primus-libs:i386

Tip for users with Optimus (hybrid) graphics chipsets with bumblebee-nvidia driver installed:

1. To run a game with Nvidia support, type in the terminal: optirun (program-name)

2. You can’t install Nvidia Tweaking tool with graphical interface (Nvidia X server settings). Doing so can corrupt your system! If you’ve generated /etc/X11/xorg.conf using nvidia-xconfig, remove that file. It’s not compatible with Optimus laptops:
sudo rm /etc/X11/xorg.conf

3. To fix screen tearing in Bumblebee, you need to follow my tutorial for INTEL cards:

4. All Nvidia tweaks should be done through modifying
/etc/bumblebee/xorg.conf.nvidia configuration file
