Linux Hint

Recommended Posts

Unlike Windows and Mac, Linux still provides lifelong support for older machines with its various distributions. This is what I like most about Linux and its distributions. Even if you cannot carry out larger tasks, you can still carry out normal day-to-day tasks such as web browsing, writing/editing word document, watching movies, or listening to music. So why throw your old machine if you can still make use of it?

We will look at the best Linux distributions that can be easily used and installed on older computers with minimal hardware. Some of the Linux distributions listed here might be useful for beginners also.

So, let’s get started and have a look at lightweight Linux distros for an old laptop.

You can install Slax on a USB flash drive so that you can carry it anywhere in your pocket and run on any computer. Maybe that’s why they call it a pocket operating system. Slax is based on Debian, which ensures good community support and updates.


Slax ships-in with a handful of useful pre-installed applications such as Terminal, Web Browser, and others. It is available in both 32-bit and 64-bit versions. This installation ISO file size is just around 270 MB, which makes it an ideal Linux distro for older laptops.
