It is a lightweight Linux distro specifically made to run on computers with limited capabilities. Bodhi Linux is a light release that comes with Moksha Desktop.

It is also possible to use the AppPack edition, a live system-based OS that connects to your PC and runs the standard applications.

With the most recent version of Ubuntu MATE, you’ll find many new features and improvements. This includes various color themes, an easy install, the experimental ZFS, and GameMode by Feral Interactive. This is among the best desktop environments and that’s why you will get a more refined look with MATE, which you could even run on limited hardware.


Additionally, Ubuntu MATE also offers an elegant Linux experience that will help make the transition for a Windows user an enjoyable experience. We often criticize the smaller Linux distros that do not use many resources; however, that’s not the case with Ubuntu MATE.

Arch Linux + Lightweight Desktop environment

If you are someone who likes to customize and personalize your system, I’d recommend Arch Linux. The desktop interface in your OS can make it light or heavy. Arch is essentially a simple lightweight Linux distro that isn’t loaded with a large number of pre-installed applications.

I would recommend that you try a lightweight window manager such as i3. It’s said that the most efficient DE does not have one in the first place. If you’re looking to change Arch to a speedy and light Linux distribution with an environment for desktops, several options are available, including amazing Xfce and the LXQt.

It is important to note before deciding on Arch Linux. Make sure your system isn’t built on 32-bit technology, as Arch makers have stopped providing 32-bit versions due to the declining popularity of 32-bit platforms. You can opt for the forked archlinux32 version also.

Of the projects established following the CrunchBang era, BunsenLabs is the only one still being maintained. The lightweight Linux distro follows the CrunchBang trend and uses a Debian base with a simple user interface and Openbox window manager as well as a BunsenLabs-specific software repository.

There are 32-bit and 64-bit versions available that work with each of the x86 and ARM processors. The minimum system requirements are set at 1GB RAM, with the complete installation of the current ISO is approximately 2.1GB. BunsenLabs is faithful to its CrunchBang origins.

The most recent version was an upgrade of the current Ubuntu LTS. The focus of this lightweight Linux distro is on reviving old devices, and the distro has been intended to be an operating desktop straight out of the box. It’s designed to appeal to current Windows users.

The programmers spend substantial time implementing every necessary modification and tweaks that improve performance, yet they do not skimp on the finer things. The program’s aesthetics is a significant aspect of the game, as shown by the variety of wallpapers available in the app and clones of Windows applications such as Aero Snap or Expose.

The lightweight Linux distro includes full-featured applications across various categories like audio and video, internet graphics, office games, and much more. There are also valuable tools, such as an app for weather that runs on terminals and Penguin Pills, an interface that can be used as a graphic for various antivirus scanners.
