“Ubuntu” is an ancient African word, meaning “humanity to others”. Edubuntu seeks to bring the freedoms and spirit of Ubuntu to children, parents, students, teachers, and schools.

Included with Edubuntu is the Linux Terminal Server Project, a large number of educational applications including GCompris, KDE Edutainment Suite, and Schooltool Calendar.

The first Edubuntu release coincided with the release of Ubuntu 5.10, which was codenamed Breezy Badger on 2005-10-13. Edubuntu CDs were previously available for free through their Shipit service. However, as of version 8.10, it is only available as a download.

Qimo’s interface has been designed to be intuitive and easy to use, providing large icons for all installed games, so that even the youngest users have no trouble selecting the activity they want.

Qimo is based on Xubuntu; a community maintained derivative of the Ubuntu operating system, using the Xfce desktop environment.[4][5] This helps provide low hardware requirements; minimum of 256MB of memory to run from the CD, or 192MB to install. At least 6 GB of hard drive space is recommended, and a 400 MHz or faster CPU.[2] Qimo currently uses 8.04 LTS with plans to use the next LTS Lucid Lynx.

Differences between Qimo & Edubuntu:

- Qimo was designed to be a standalone home computer for kids

- Edubuntu was designed for networked classroom computer use

- Qimo will run from a LiveCD

- From October 2008 to October 2009, Edubuntu required an existing Ubuntu installation. Edubuntu is available in a live medium, but only on a DVD, as its contents will not fit on a CD anymore.

- Qimo and Edubuntu are working to bring the Qimo games and artwork as an installable option within Edubuntu.
