Ututo
Ututo is a Linux distribution consisting entirely of free software. The distribution is named for a variety of gecko found in northern Argentina.
Ututo is compiled using Gentoo Linux ebuilds and emerge software. All documentation is in Spanish.
Ututo was the first fully free Linux-based system recognized by the GNU Project. The founder of the GNU Project, Richard Stallman, formerly endorsed the distribution nearly exclusively, and used it on his personal computer, before he switched to gNewSense, and later Trisquel.
Ututo has different binaries optimized for different Intel and AMD processors .
With no releases since 2012 the distribution is considered "dormant".
