Ututo is a GNU/Linux distribution consisting entirely of free software. The name makes reference to a gecko known by this name from northern Argentina. It is compiled using Gentoo Linux "ebuilds" and "emerge" software. All documentation is in Spanish.
Ututo was the first fully free Linux system recognized by the GNU Project. The founder of the GNU Project, Richard Stallman, formerly endorsed the distribution nearly exclusively,  and used in his personal machine, before he switched to gNewSense, and later Trisquel
Ututo was first released in 2000 by Diego Saravia in National University of Salta. Argentina. It was one of the first live CD distributions in the world and the first Linux distribution in Argentina, under ISBN 987-9381-06-8. Ututo carried Simusol, a system to simulate Solar Energy projects. Ututo was called the simple GNU/Linux, because it did not need any configuration. It automatically detected the hardware in the machine, it only asked to "move your mouse". At that time no other distribution worked that way.[need quotation to verify]
In 2004, the Ututo-e project was born, swiftly becoming the most important derivative of Ututo. This project was started by Daniel Olivera.
The latest versions of Ututo are called "Ututo XS". With the emergence of the XS series, there have been many new features, including a faster system installer. It's being used in different hardware projects such as iFreeTablet.
The emergence of a package management system for Ututo has been the topic of many discussions over a few years. Pablo Manuel Rizzo has designed Ututo-Get, a tool for maintaining a package database modeled after Debian's APT; however, as other Gentoo-based distros, Ututo is compatible with Portage.
