Install NVIDIA drivers the right way on Linux

Just a couple of months back I had bought a new laptop with Intel Core i5-6200U processor and NVIDIA GeForce 930M GPU. The first thing I tried to do was to install the graphic drivers.

So, being a Linux noobie at that time, I googled this thing and I ended up here (AskUbuntu being a reputed site, became my first choice among the search results). I did what the solution said, and ended up screwing my distro, it wouldn't proceed past the login screen. I tried doing what a few other sites were telling, all ending up the same road. I tried using Ubuntu's own Software Updater app too, ending on the same note again.

Until one day I discovered that I could directly install the Graphics Driver from the Terminal without any hassles (sigh -_-)

WHAT NOT TO DO

These are what I tried ending up on the same road (not going past the Login screen despite the correct credentials)

• Trying to update via .run files provided by NVIDIA's official site
• Trying to update via Ubuntu's very own Software and Updates app.
• Having the following two repos and installing the driver via terminal
  

   ppa:xorg-edgers/ppa
   ppa:mamarley/nvidia

•  Updating the kernel (unless you install the drivers)

WHAT TO DO

Now it's a really simple process on Ubuntu 16.04 (Doing this on 15.10 was hell, checked the X Server Log Files and didn't get anything special to boast about)

Run these steps:

• $ sudo apt update

• $ lshw -numeric -C display
  or
  $ lspci -vnn | grep VGA  

  
   (As a root user). The Output will show your Nvidia Model Number. Example:
  

  $ lshw -numeric -C display

• The Model used by my system is GeForce 930M. Next, we will find a correct NVIDIA driver within the Ubuntu repos using this info. But before that, navigate here and enter details. Example:
  
  


• After a successful search, take a note of the driver number:
  

  Version:  361.42
  Release Date:  2016.3.30
  Operating System:  Linux 64-bit
  Language:  English (US)
  File Size:  82.74 MB 



• Then install the corresponding driver
  

  $ sudo apt-get install nvidia-361
  ...
  Done.

• Now you can reboot your system. Then after loading Ubuntu, you can load the X Server Settings app:
  
  

CONCLUSION

So that's it, folks. This is the safest and a recommended way to install NVIDIA drivers for Linux. And I repeat, do not install the drivers using the .run file
