The Trinity Desktop Environment (TDE) project is a computer desktop environment for Unix-like operating systems with a primary goal of retaining the function and form of traditional desktop computers.
The TDE project began as a continuation of the K Desktop Environment (KDE) version 3. The name Trinity was chosen partly because the word means “three” and TDE was a continuation of KDE 3. TDE now is its own computer desktop environment project.
The TDE project was founded by and is still led by Timothy Pearson. Timothy is an experienced and skilled software developer and was the KDE 3.x coordinator of previous Kubuntu releases.
Trinity is provided to Sparky as a 3rd party desktop, and uses a 3rd party repositories, which lets you install the desktop in two ways:
1. Fresh install - using Sparky MinimalGUI/CLI iso images. Running the Minimal ISO, launch Sparky Advanced Installer and follow the installation process which lets you install one of 20 about desktops, including Trinity.
This desktop has been removed from installation list of Minimal iso images.
2. Sparky APTus - the Desktop tab provides an option which lets you install one of 20 about desktops, including Trinity, alongside an existing desktop.
