From ArchWiki

From the Trinity Desktop Environment (TDE) project page:

TDE is a complete software desktop environment designed for Unix-like operating systems, intended for computer users preferring a traditional desktop model, and is free/libre software. Born as a fork of KDE 3.5 back in 2010, TDE is now a fully independent project with its own personality and development team, available for various Linux distributions, BSD and DilOS.

TDE still depends on an old version of Qt, which they now maintain themselves, since it is deprecated. The Trinity applications and applets should also work with other desktop environments.


Binary packages

Install either the tde-tdebase package from the trinity repository for a base Trinity environment, or tde-meta for a more complete one.

If you have any errors during an upgrade, add the 0x8685AD8B key by following pacman/Package signing#Adding unofficial keys.

Build from source

Trinity Packaging repository contains PKGBUILD files for most Trinity packages in the "arch" folder.

The sources are in a git repository. More info on cloning it is at their GIT information page.

The suggested build order is specified in the How to Build TDE page.

Note: See DeveloperWiki:Building in a clean chroot to build the packages in a chroot.



To start Trinity from the Linux console:

$ startx /opt/trinity/bin/starttde

See xinit for more.


tde-tdebase comes with TDE Display Manager. To start it at boot, enable the tdm.service.
