The following worked on my very old hp dv6500 laptop. Haven't yet tested it on any other type of laptop/computer. I don't know if it would work on any other computer, so Do It At Your Own Risk.
If you have any suggestions, please tell me so that i can make this even better. I'm a n00b when it comes to linux.
I used this technique because I didn't have 1,097 MB to spare if I had updated my kali linux system.
However, the best way of installing nvidia can be found on the following link below.

The following tutorial is a mixture of what I learnt from kali linux documentation, and my own experience of installing nvidia in ubuntu.

You need to download the latest version of nvidia drivers from their site: You will have to know the model of your nvidia driver. My model is 8400M GS.

Kali linux uses a graphics driver called nouveau, which comes in debian by default. You need to block it so as to install nvidia graphics driver.

Code:
sed*'s/quiet/quiet nouveau.modeset=0/g'*-i*/etc/default/grub
update-grub
Secondly, we can blacklist nouveau manually by adding the following to /etc/modprobe.d/kali-blacklist.conf

blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv
Thirdly, uninstall any previous nvidia drivers, just incase you have any in your system.

root@kali:~# sudo apt-get --purge remove nvidia-*
Once saved, you'll need to stop gdm3 so as to be able to install the driver. From here, you'll use commands to get to the nvidia driver.

service gdm3 stop
Then press Ctrl-Alt-F1 to enter your username and enter your password. Go to the folder that contains the nvidia driver, and run the following command .

sh NVIDIA-Linux-x86-331.49.run
(depending with which version you got.)

From there, just follow the instructions given by the program.
Once you have finished installing, type
reboot
