Lumina is a lightweight desktop environment that is free of D-Bus (and all its failures) and *kit and is designed to have as few system dependencies and requirements as possible. Check out the Lumina Wikipedia article and their official handbook.

To install Lumina desktop, run:

pacman -S lumina lumina-extra

A configuration file is installed in /etc/luminaDesktop.conf . Lumina also has a bunch of own configuration tools.

Lumina provides its own replacement for startx to be started from console.

start-lumina-desktop

Alternatively it can be added to the ~./xinitrc file for being started via startx or a display manager

Make sure to read this article, for more information on managing startx on Arch GNU/Linux (the information applies to Hyperbola, as well). But relevant commands are bellow:

[[ -f ~/.Xresources ]] && xrdb -merge -I$HOME ~/.Xresources
exec start-lumina-desktop
