Inspired by Bunsen Labs Linux which is based on Debian,
the ArchLabs Linux distro is based on Arch Linux
Found this easier to install than Arch Linux manily due to the text installer called Arch Labs Installer(ALI) which the Arch Labs Linux developers have added.
I installed OpenBox and found the system responsive.
You need to righ click then choose preferences and then conky chooser and you Sthen enable Conky. Conky is a light weight system monitor.
A freshly installed system with a few terminal windows open was taking only around 350 MB of memory usage.
At first i found there was no sound then i found that the volume was set low and then i had to increase the volume.
