Linux Nvidia driver installation - fix second monitor detection

Nvidia display issue.

I was facing difficulty in detecting second monitor in my linux machine. 

I had tried few online solutions but couldn't get it done.

Finally the solution which worked:

 

1.

Detect the specific VGA controller in your machine.

# lspci | grep VGA

2. Now, go to https://www.nvidia.com/en-us/drivers/ and manually search the driver inputting the specific version you obtained in step 1.

3.  For example, in my case it was this file: NVIDIA-Linux-x86_64-550.135.run

4.  Add executable permission
chmod +x NVIDIA-Linux-x86_64-550.135.run

5. Understand what it is:
./NVIDIA-Linux-x86_64-550.135.run --help 

6. 
To build and install the drivers , run the script. 
( This is quite interesting file I come across, it is both a script as well as binary..need to explore more on this later )

./NVIDIA-Linux-x86_64-550.135.run

7. Boot after installation, you should be able to detect the second monitor.
