Heya, happy new year 
, for start with great stuff this year, I just Debian again after two years of using Kubuntu/Windows-lately, and I had few problems installing Nvidia drivers, with the repository drivers, so I wrote a little guide of how to make it with Nvidia site drivers – this guide is meant for working with 64 bits operating system and that you have closed the X system.
Downloading the needed stuff, nvidia driver, the kernel headers, changing permissions and installing it
wget http://us.download.nvidia.com/XFree86/Linux-x86_64/190.53/NVIDIA-Linux-x86_64-190.53-pkg2.run
apt-get install linux-headers-$(uname -r)
chmod +x NVIDIA-Linux-x86_64-190.53-pkg2.run
sh NVIDIA-Linux-x86_64-190.53-pkg2.runAnd depending of what desktop manager do you use, you will start it (gdm, kdm, w/e)
/etc/init.d/kdm start or restart (depends if it is running)
/etc/init.d/gdm start or restart (depends if it is running)If it doesn’t run, just run
dpkg-reconfigure xserver-xorg
