There are many situations when we need to keep our computer running without using monitor. It usually happens when we are downloading any large file or when we are leaving our computer for a short while. In such a case, most of us leave our computer monitor turned ON even though it is not required until the power saving system automatically turns it off after some time. Monitor consumes a significant amount of power. So, turning it off when not in use will save power.


You might be thinking "why not use the button provided to turn off our monitor?"
Yes, you can do that way but not always. It can cause wear and tear and the button may get damaged sometimes as it has happened to me now (esp if you had an old monitor). Also, this button is not provided for most laptops these days. In this article I will tell you an easy solution to turn Off your monitor on Linux.

In the previous post, I have shared the executable of "program to solve system of linear equations with step by step solution". I got many requests from the readers to publish the source code. So I have rewritten the source code from scratch in C language. This version has a few impressive improvements than the previous one. In this article, we shall have a brief introduction to this program with a screenshot tour. The download links for the executables along with the source code are available for download on my facebook page.

Four years ago when I was in my first year of B-Tech, I have written a program in C to solve for given system of linear equations. I actually wrote it for my personal use then. Once my maths lecturer gave a long assignment on solving system of linear equations. I did not feel like doing that. So, I wrote this program to solve the equations by generating a step by step solution (so that I can copy in the assignment) and also give information about all the related properties like rank of the matrix, nature of solution, etc. (If you are in a hurry, you can scroll down the page to quickly download the program)
