Draco Desktop Environment

Draco is a simple and lightweight desktop environment. While small still features XDG integration, freedesktop services and integration, power and storage management, desktop, panels, multi-monitor support and much more. Draco does not include any user applications.

Draco is developed for and on Slackware Linux, but is also compatible with RHEL/CentOS/Fedora and others. Draco is a fork of Lumina.

Screen saver

Draco depends on XScreenSaver to handle the screen session, the default settings may need to be adjusted. You can launch the (XScreenSaver) configuration GUI with the xscreensaver-demo command or from settings.

Recommended settings are:

A custom configuration tool will be added in the future.

Hibernate

A swap partition (or file) is needed by the kernel to support hibernate/hybrid sleep. Edit the boot loader configuration and add the kernel option resume=<swap_partition/swap_file>, then save and restart.

Note that some distributions don’t require resume=, and some have hibernation disabled. Consult your distribution documentation regarding hibernation.

Build

Daemon notice

Draco includes a power daemon (to be able to adjust screen and cpu) this daemon must run as root (or a user with write access to /sys), this service run through D-Bus and can only be accessed by a predefined system group, this should be a common desktop user group like power or something similar. The default when building Draco is root as user and power as group. If you want something else you can change this during build.

Add the following during cmake configure:

-DPOWERD_SERVICE_USER=<run service as this user>
-DPOWERD_SERVICE_GROUP=<user group that have access to service>

You can also change the /etc/dbus-1/system.d/org.dracolinux.Powerd.conf file manually if you want.

Slackware Linux (14.2+)

Install the following packages from SlackBuilds.org or slackware.com/~alien:

The rest should be available in a standard installation.

A draco.SlackBuild is available.

You can of course build it manually:

mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib64 -DCMAKE_INSTALL_MANDIR=/usr/man -DCMAKE_INSTALL_DOCDIR=/usr/doc -DCMAKE_BUILD_TYPE=Release ..
make
sudo make install

Note that the install prefix should be the same folder as D-Bus (usually in /usr), else you will need to copy the Draco service files to the proper location manually.

Ubuntu (Xenial+)

Minimal testing is done on Ubuntu, some features may not work.

Known issues:

Dependencies (based on a miminal install of Xenial):

Build and install:

mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib64 -DCMAKE_INSTALL_LIBEXECDIR=bin -DCMAKE_BUILD_TYPE=Release ..
make
sudo make install

Note that the install prefix should be the same folder as D-Bus (usually in /usr), else you will need to copy the Draco service files to the proper location manually.

RHEL/CentOS/Fedora

Minimal testing is done, some features may not work.

Known issues:
