  1. Fast Linux is great for older hardware. It’s a DIY load of Debian tailored for old computers. I’m using it now on a 1.2GHz cpu laptop!

  2. For me, best choice are Puppy family from the lighter Thar to Xenial or Bionic and Linux Lite. We need a light distro that have some basic software (Libre Office or, at least. Abiword, VLC, simplescreen recorder, that records areas of your screen and as such can copy Youtube videos, Gimp, etc), easy installation of extra applications and a browser that can digest sites with lots of CSS coding. Older browsers can not handle them. Even some browsers can not read microsoft site!

  3. Interesting article, but I have a really hard time seeing anything based on Ubuntu as light weight. And the Lubuntu minimums are pure fantasy. It won’t even run on a system with the base specs they state–Pentium II is pure fantasy. Some tester may have a PII they tricked it into running on, but it fails on all of mine. On a PIII is is a hopeless pig, and unusable though it sort of runs. P4 is possible, but it’s still very, very slow. Atom single core is just as bad.

    I haven’t tried the new Puppy yet, but it’s considerably heavier than its earlier versions. I do look forward to giving it a spin on my older systems.

    Tiny Core really is light, but it’s more like an embedded Linux than a regular light Linux.

    Unlisted, even as a “contender”, is AntiX. AntiX Full will run capably on a 700MHz Atom with 1GB of RAM. A second GB makes it much faster. It needs just a smidge over 4GB of disk to install. It runs amazingly well off a USB stick or SD card, even on an old system with USB 2.0. And that’s the -heaviest- version of AntiX. From heaviest to lightest the AntiX versions are Full, Base, Core, and Net. Base drops LibreOffice and a couple of other full-fat applications, Core has only the most basic graphic interface, and Net is headless.

    • Thank you, Mark Graybill! An honest comment.

      I’m getting a bit tired of seeing upper-middle weight distros being passed off as light. Also getting tired of fanboys not seeing their fav distro listed (regardless of the theme of the article) and asking “What about my bloated distro? Why isn’t my bloated distro not listed among lightweight distros for old computers?”.

      As soon as I see Lubuntu on any list of lightweight anything… I move on. The only two that are lightweight on this list are TinyCore and Puppy. Tried them both. Also tried antiX – amazing on old hardware. I even like MX on old hardware (a kinda’ fuller-featured version of antiX) – it’s faster than Linux Lite and Lubuntu. Source? I actually try them all on my old equipment.

      • Have you tried Trisquel Mini? I don’t think you have cos you didn’t write it off as not being lightweight. It’s one of the lightest on the list. I just tried it yesterday and when idle, it was taking 150 mb of ram. Is it not lightweight?

    • Agree…IMHO MX16 is totally underrated…I love Puppy Linux but haven’t found a more functional, hassle free and fun distro than MX16.

    • It’s a Small list of lightweight Linux distros. So i could not accumulate all but i have included peppermint in mentionable para.

    • Basically, it’s really difficult to enlist only 5 lightweight Linux Distros. I am totally agreed with you. Gentoo Linux is one of the smallest Linux distros.

  4. What is great about Puppy Linux is that they have several different sub-projects, each geared to a specific level of newer or older hardware. What I usually do on a person’s computer is to start with Lubuntu if the hardware isn’t really old, and then work through the various Puppy’s if I have to, until I find a version that is speedy enough. It is all about a trade-off of GUI and features verses speed. I have a lot of practice with people wanting to replace XP with an OS that continues to get security and application updates.

    • This piece of information, you shared, is really useful and effective for those who want to use Lightweight Linux Distros in their old machine. Thanks for your valuable comment.

  5. I have used many of them because I have no money enough to buy a modern PC or Laptop like many people of course and the best for me is Puppy Linux. Thanks for the article. See you.
