Trinity

The Trinity Desktop Environment (TDE) project is a computer desktop environment for Unix-like operating systems with a primary goal of retaining the overall KDE 3.5 computing style. The 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.

The goal of this project is to keep the KDE3.5 computing style alive, as well as polish off any rough edges that were present as of KDE 3.5.10. Along the way, new useful features have be added to keep the environment up-to-date.

The current stable release of TDE (3.5.13) was released Nov 1st 2011. A software release update (SRU) for 3.5.13 is planned in late 2012. Current development is on 14.0.0. Both 3.5.13(sru) and 14.0.0 build on Arch with all current libraries. The old stable 3.5.12 release was packaged as an updated kdemod3.

Note: Backwards compatibility with 3.5.X was dropped in 14.0.0 to allow install of TDE/TQt without conflict with KDE4/Qt4.

The difference between 3.5.13 and 14.0.0

The versioning change between 3.5.13 and 14.0.0 signifies that backwards compatibility with 3.5.X has been dropped to allow TDE/TQt to install along side KDE4/Qt4 without conflict. 14.0.0 will continue to rely on HAL, but subsequent releases will do away with that dependency. 14.0.0 contains the first prototype of media:/ kioslave as a replacement for HAL. 3.5.13 continues backwards compatibility with KDE 3.5.10 code and provides an alternative choice for those that prefer. The 3.5 13 branch will be maintained for the forseeable future.

Currently the remaining TQt name changes are being implemented after which a tentative code 'freeze' is anticipated to allow user testing and bug identification. 14.0.0 will be a true TDE release with all branding, artwork, and graphics changed and updated for this project rather than using the holdover KDE3 stock images. All in all, the desktop functions beautifully on current graphics libs, systemd-tools, libusbx, udisk2 and other newly implemented hardware paradigms.

Installation

Currently development packages for Arch Linux are available for both 3.5.13-sru and 14.0.0. Server space has been graciously provided by maevius.

For stable 3.5.13-sru snapshots add to your /etc/pacman.conf:

[tde3513]
Server = http://archlinux.us.to/3.5.13/$arch

Note: If you have installed packages before 8/18/12, tde-tdeartwork was misssing. Please install that package to insure your selection of screensavers are complete.

For development 14.0.0 snapshots (expected by 9/1), add to your /etc/pacman.conf:

[tde1400]
Server = http://archlinux.us.to/14.0.0/$arch

Meta package installation for tde is provided under the name tde-base. Simply install with:

pacman -Sy tde-base

Note: On install, you should expect conflicts with tde-sip and tde-sip4-tqt. The TDE packages tde-sip and tde-sip4-tqt are direct replacements for the sip and python2-sip packages. They simply contain additional extensions for TDE. If you encounter these conflicts, the recommended install is:

pacman -Rdd sip python2-sip
pacman -Sy tde-base

Warning: If attempting to install 3.5.13 along side KDE4 you will experience conflicts with libart-lgpl and kdebase-workspace. The libart-lgpl packages are equivalent. The kdebase-workspace conflict is with /etc/ksysguarddrc. Both are in the process of being eliminated.

Start and configuration

After a successful install of TDE, starting TDE from the command line or configuring /etc/inittab to launch tdm is straightforward. The init script for the display manager has been renamed from kdm to tdm to avoid conflicts.

Configure to work with startx

Trinity provides a normal starttde in /opt/trinity/bin (symlink provided in 3.5.13). The easiest way to start Trinity is to simply add /opt/trinity/starttde entry at the end of ~/.xinitrc. If you do not presently have ~/.xinitrc, then simply create it with the following entry:

~/.xinitrc

exec /opt/trinity/bin/starttde

Then from the command line, just type startx.

Configure with kdm greeter

Trinity provides a great looking tdm graphical interface. The tde-tdebase PKGBUILD has been updated to install the trinity.desktop file in /etc/X11/sessions. In order to automatically lauch tdm on boot, edit /etc/inittab and change the runlevel 5 x startup to:

x:5:respawn:/opt/trinity/bin/tdm -nodaemon

If you modified inittab in runlevel 3, you can use telinit to initialize the runlevel 5 services from the command line.

If you experiment with other display managers (slim, etc..) please drop a quick howto here.

Build from source

PKGBUILDs - current git code

For a snapshot of PKGBUILD sources for building against the current GIT tree, see R14 and 3.5.13-sru. Be sure to read the README-building.txt.

Note: Final PKGBUILD source files will be moved to the tdepackaging GIT tree after 14.0.0 is released.

Build order

The required build order is specified in the Trinity-HowToBuild. After building tdebase, you can start the desktop.

Warning: Trinity on Arch must be built in a clean environment without KDE4 present.

Set up your chroot for building by referencing DeveloperWiki:Building in a Clean Chroot. Make sure you configure your local repository in $CHROOT/root/repo and add each package built to the repository as outlined in the DeveloperWiki.

Example

 # mkarchroot -u $CHROOT/root
 # makechrootpkg -c -r $CHROOT
 # makechrootpkg -r $CHROOT    

Which means respectively:

1. update the chroot
2. build first package with the -c option
3. build remaining packages without update }}

Known issues

Issues for 3.5.13-sru

The following are issues that are specific to the 3.5.13-sru release:

KHelpCenter documentation from packages built with autotools are installed in /opt/trinity/share/doc/HTML while documentation from CMake packages are installed in /opt/trinity/share/doc/kde/HTML. This means roughly one-half of the help files are missing from the khelpcenter browser. This is currently being fixed in the GIT tree and the next set of packages will have all help documentation in the chosen standard location of /opt/trinity/share/doc/tde/HTML. This also insures a future /usr install will not conflict with any KDE help files. As a workaround in the mean time, after installing 3.5.13-sru:

cd /opt/trinity/share/doc/kde/HTML/en
for i in ../../../HTML/en/*/; do ln -s $i; done

Note: Substitute your language for en

Package tde-tdesvn for x86_64 had been built with libpath /opt/trinity/lib64 and /opt/trinity/lib64/trinity , but there was no any records in libpath about them. Then, starting kdesvn you get error libkdesvnpart.la not found in paths. As a workaround you may copy/symlink libraries from /opt/trinity/lib64 and /opt/trinity/lib64/trinity into /opt/trinity/lib and /opt/trinity/lib/trinity respectively or try to create libpath record and ldconfig after it.
