Trinity is a lean fork of the mainline KDE 3.5 desktop environment initially targeting Kubuntu users. This is specially for users who used to love the functionality and snappiness of KDE 3.5. Trinity codebase uses Qt heavily and has its own software in many categories. Yesterday the Trinity team released TDE R14.0.0 which was being developed for 2 years. It brings many improvements like a new hardware manager based on udev (HAL is no longer required), full network-manager 0.9 support, a brand new compositor (compton), built-in threading support, and much more! With this new development Trinity has the potential to become a stable choice for KDE fans. You can either download the LiveCD or install it as an alternative DE to try it out.
To install the latest TDE on Ubuntu Trusty (14.04), run the following commands:
$ echo "deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-r14.0.0/ubuntu trusty main" | sudo tee -a /etc/apt/sources.list.d/trinitydesktop.list > /dev/null $ echo "deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps-r14.0.0/ubuntu trusty main" | sudo tee -a /etc/apt/sources.list.d/trinitydesktop.list > /dev/null $ sudo apt-key adv --keyserver keyserver.quickbuild.pearsoncomputing.net --recv-keys F5CFC95C $ sudo apt-get install aptitude $ sudo aptitude update $ sudo aptitude install kubuntu-default-settings-trinity kubuntu-desktop-trinity
As you might have guessed already, to install on other versions of Ubuntu, you need to change the release name trusty in the first two commands above.
