Trisquel (full name Trisquel GNU/Linux) is a computer operating system, a Linux distribution, derived from another distribution, Ubuntu. The project aims for a fully free software system without proprietary software or firmware and uses a version of Ubuntu's modified kernel, with the non-free code (binary blobs) removed. Trisquel relies on user donations. Its logo is a triskelion, a Celtic symbol. Trisquel is listed by the Free Software Foundation as a distribution that contains only free software.

Trisquel
The standard Trisquel distribution includes the MATE desktop environment and graphical user interface (GUI), and English, Spanish and 48 other localizations, 50 in total, on a 2.6 GB live DVD image. Other translations can be downloaded if an internet connection is present during installation.

Trisquel Mini
Trisquel Mini is an alternative to mainline Trisquel, designed to run well on netbooks and older hardware. It uses the low-resource environment LXDE and lightweight GTK+ and X Window System alternatives to GNOME and Qt-KDE applications. The LXDE desktop only includes English and Spanish localizations, and can install from a 1.2 GB live DVD image.

Triskel
Triskel is another alternative to mainline Trisquel using the KDE graphical interface, available as a 2.0 GB ISO DVD live image.

Trisquel Sugar TOAST
Sugar is a free and open source desktop environment designed with the goal of being used by children for interactive learning. Sugar replaces the standard MATE desktop environment available with Trisquel.

Trisquel NetInstall
NetInstall consists of a 25MB CD iso image with just the minimal amount of software to start the installation via a text based network installer and fetch the remaining packages over the Internet.
