Ubuntu Titling or Ubuntu-Title is a rounded geometric sans-serif font.
 It was created by Andy Fitzsimon for use with the Ubuntu operating system and its derivatives.
 It is distributed under the GNU Lesser General Public License.
 Prior to the 10.04 release, the typeface was notably used in branding for the Ubuntu operating system and its related projects.
 Fitzsimon's design was created without any upper-case letters.
 A later release by Christian Robertson (who later created Roboto) added capitals and was released by Robertson at the 'release candidate' stage.
 This was called Ubuntu Titling.
Xubuntu ( ) is a Canonical Ltd.–recognized, community-maintained derivative of the Ubuntu operating system.
 The name "Xubuntu" is a portmanteau of "Xfce" and "Ubuntu", as it uses the Xfce desktop environment, instead of Ubuntu's Unity.
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.
Ubuntu is an OpenType-based font family, designed to be a modern, humanist-style typeface by London-based type foundry Dalton Maag, with funding by Canonical Ltd.
 The font was under development for nearly nine months, with only a limited initial release through a beta program, until September 2010.
 It was then that it became the new default font of the Ubuntu operating system in Ubuntu 10.10.
 Its designers include Vincent Connare, creator of the Comic Sans and Trebuchet MS fonts.
Unity is a graphical shell for the GNOME desktop environment originally developed by Canonical Ltd. for its Ubuntu operating system.
 Unity debuted in the netbook edition of Ubuntu 10.10.
 It was initially designed to make more efficient use of space given the limited screen size of netbooks, including, for example, a vertical application switcher called the "launcher", and a space-saving horizontal multipurpose "top menu bar".
Ubuntu releases are made semiannually by Canonical Ltd, the developers of the Ubuntu operating system, using the year and month of the release as a version number.
 The first Ubuntu release, for example, was Ubuntu 4.10 and was released on 20 October 2004.
 Consequently, version numbers for future versions are provisional; if the release is delayed until a different month (or even year) to that planned, the version number will change accordingly.
