Here's a Linux Distro that, for some reason. I don't remember ever trying out. And I've been running Linux since 2005 and I've tried out at least 50 Linux Distros. Some the same Distro, but different versions. I have several old computers and Manjaro is suppose to be low on Resource Usage. So, I guess it's about time to try out Manjaro!;) I'm Downloading the Manjaro Openbox and Community Manjaro Cinnamon & Gnome Editions Now.

Update: So, I Booted up Manjaro Openbox and Community Manjaro Cinnamon & Gnome Editions om Virtual Box. I like Manjaro Community Manjaro Cinnamon & Gnome Edition's Desktop, best. But, it may not run well in an older Machine. I ran it in a VM with 768MB of Ram and 64MB of Video. It did give a warning, saying that the Hardware was not setup and working right. And said that it would run much slower, in this condition. I'm sure, that was because it was running in a Virtual Machine, instead of a Real Hardware System. So, I will have to actually Boot it in a Real Machine to know for sure, how much resources it needs to run well. But, Manjaro Openbox Edition, ran quite well. I'm thinking, that it would be the best choice for my old P2's and 3's. They only have 195 and 256MB of Ram and 64MB Video Cards. Since Manjaro Openbox was only using about 115MB of Ram, while running. There is a great Desktop App, that shows the System Resources. And it starts up with the System by default. I like that on Older Systems. That way you can just glance at your Desktop to see what's going on. Especially if you try to open an app and nothing seems to happen. This is much better than those little Fiery looking Icons on some Systems. This actual Text, Overlaid on the Desktop Background. I need to make a note of that Apps name and start installing it on my other old Systems. So, I think I will soon be Trying out Manjaro Openbox and Community Manjaro Cinnamon & Gnome Editions on some Real Hardware Systems...

About - Manjaro Linux

Manjaro is a user-friendly Linux distribution based on the independently developed Arch operating system. Within the Linux community, Arch itself is renowned for being an exceptionally fast, powerful, and lightweight distribution that provides access to the very latest cutting edge – and bleeding edge – software. However, Arch is also aimed at more experienced or technically-minded users. As such, it is generally considered to be beyond the reach of those who lack the technical expertise (or persistence) required to use it.
Developed in Austria, France, and Germany, Manjaro provides all the benefits of the Arch operating system combined with a focus on user-friendliness and accessibility. Available in both 32 and 64 bit versions, Manjaro is suitable for newcomers as well as experienced Linux users. For newcomers, a user-friendly installer is provided, and the system itself is designed to work fully ‘straight out of the box’ with features including:

Pre-installed desktop environments
Pre-installed graphical applications to easily install software and update your system, and
Pre-installed codecs to play multimedia files

For more experienced – and adventurous – users Manjaro also offers the configurability and versatility to be shaped and moulded in every respect to suit personal taste and preference. Furthermore, a minimalist NET-Edition is also available in both 32 and 64 bit versions. Stripped of any pre-installed software, this provides a base installation on which to build your own system; starting from a command line, be completely free to chose your own greeters, desktops, hardware drivers, software applications, and so on!

Features

Manjaro shares many of the same features as Arch, including:

Speed, power, and efficiency
Access to the very latest cutting and bleeding edge software
A ‘rolling release’ development model that provides the most up-to-date system possible without the need to install new versions, and
Access to the Arch User Repository (AUR).

However, Manjaro boasts a few extra features of its own, including:

A simplifed, user-friendly installation process
Automatic detection of your computer’s hardware (e.g. graphics cards)
Automatic installation of the necessary software (e.g. graphics drivers) for your system
Its own dedicated software repositories to ensure delivery of fully tested and stable software packages, and
Support for the easy installation and use of multiple kernels.

Openbox is a highly configurable, next generation window manager with extensive standards support. It allows you to change almost every aspect of how you interact with your desktop and invent completely new ways to use and control it. It can be like a video game for controlling windows. But Openbox can also be kept extremely simple, as it is in the default setup, meaning that it can suit just about anybody. Openbox gives you control without making you do everything.
