ADMOS-Lite (previously known as minimalubuntu) is an operating system that features LXDE and lightweight programs based on Ubuntu (operating system), but it is not an official project by Canonical Ltd. The goal of ADMOS-Lite is to create a distribution based on Ubuntu that is reasonably fast even on limited hardware & consists of 100% free software only. In contrast to other variants of Ubuntu, ADMOS-Lite is focused on providing a trimmed set of software packages while providing the experience expected by a modern computer user. Furthermore, the user interface is designed to be usable even at smaller resolutions such as those on older computers and netbooks.
ADMOS-Lite uses software from the repositories of Ubuntu but also excludes non-free elements. ADMOS-Lite is promoted, developed, and distributed by the P4F Project.
