Do you have an old computer? Have you kept your old computer somewhere in a rack? So this is the time to take it out and start using it. In this article, I will walk you through the list of 5 Lightweight Linux distributions that you can install and use on old computers.

All of these 5 Linux distributions require fewer resources, therefore, can be run on old desktops or laptops. So without any further delay let’s dive in.

Lightweight Linux distributions for old computers

This list of 5 lightweight Linux distributions is not just meant for old computers but you can use them on newer computers as well. Now, why would you want to use lightweight Linux distributions on newer hardware? The reason you might not want a ton of packages or applications.

In other major Linux distributions such as Ubuntu or Fedora, there are a great number of packages already installed so that you can use them to satisfy dependencies of other applications. Although that’s perfectly fine but not useful for users who just need some apps on their computers. So for such users, these lightweight Linux distros would be great on newer hardware also.

So let’s start with number 5 in our list –

5. Peppermint

The 5th lightweight Linux for old computers is Peppermint. It is based on Ubuntu LTS, it’s lightweight and easy to use Linux distributions. If you are new to Linux and want to install Linux on your older hardware then Peppermint is a good choice for you. Peppermint uses the LXDE desktop environment that is lightweight and easy to use.

LXDE is specially designed for low hardware specifications/older machines and it is known for its extremely fast performance. ​Lubuntu also has fewer packages installed that make it lighter and faster than any other Ubuntu-based Linux distribution. But Lubuntu is not just about using it on older or low specification hardware but it can also be used on modern computers.

It comes with the core of OS and with some necessary applications such as Firefox Internet browser, Inkscape, VLC media player, etc. 

The best part of the Puppy Linux is that it loads into RAM so applications start very quickly from RAM. As you provide input to the applications, applications respond to your input. You can use Flash drive to boot into Live session and all the applications will load into RAM. So even if you eject the USB the system should work just fine.
