ArchMerge has Openbox and i3 as desktop environment like ArchLabs R2-D2. But we added XFCE to it for early Linux adopters. We promote ArchMerge as a learning platform. One of the goals in ArchMerge is to learn you how to use Arch Linux and eventually install ANY desktop environement the Arch Linux way. ArchMerge wants you to Learn, have Fun and Enjoy.
