libsfdo is a collection of libraries which implement some of the freedesktop.org specifications.

cChardet is a character encoding detector, written in Python, that binds to the C library uchardet to increase performance.

Libglib-testing is a test library providing test harnesses and mock classes which complement the classes provided by GLib. It is intended to be used by any project which uses GLib and which wants to write internal unit tests.

Localed is a tiny daemon that can be used to control the system locale and keyboard mapping from user programs. It is used among other things by the GNOME Shell. The localectl command-line tool allows you to interact with localed. This package is extracted from the broader systemd package.

UDisks provides interfaces to enumerate and perform operations on disks and storage devices. Any application (including unprivileged ones) can access the udisksd(8) daemon via the name org.freedesktop.UDisks2 on the system message bus.

Wayland-Protocols contains Wayland protocols that add functionality not available in the Wayland core protocol. Such protocols either add completely new functionality, or extend the functionality of some other protocol either in Wayland core, or some other protocol in wayland-protocols.

Some projects rely on the sd-bus library for DBus support. However not all systems have systemd or elogind installed. This library provides just sd-bus (and the busctl utility).

Libei provides a client and server implementation of the EI protocol for Wayland compositors.

Libinput is a library to handle input devices for display servers and other applications that need to directly deal with input devices.

Wev is a tool that opens a window, printing all events sent to a Wayland window, such as key presses. It is analogous to the X11 tool XEv.

Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right.

A Wayland compositor allows applications to render to a shared offscreen buffer using OpenGL ES. The compositor then culls the hidden parts and composes the final output. A Wayland compositor is essentially a multiplexer to the KMS/DRM Linux kernel devices.

power-profiles-daemon offers to modify system behaviour based upon user-selected power profiles. There are 3 different power profiles, a "balanced" default mode, a "power-saver" mode, as well as a "performance" mode. The first 2 of those are available on every system. The "performance" mode is only available on select systems and is implemented by different "drivers" based on the system or systems it targets. In addition to those 2 or 3 modes (depending on the system), "actions" can be hooked up to change the behaviour of a particular device. For example, this can be used to disable the fast-charging for some USB devices when in power-saver mode.

Libinput is a library to handle input devices for display servers and other applications that need to directly deal with input devices.

fprintd is a D-Bus daemon that offers functionality of libfprint, a library to access fingerprint readers, over the D-Bus interprocess communication bus. This daemon layer above libfprint solves problems related to applications simultaneously competing for fingerprint readers.

poweralertd is a daemon that watches for UPower events and notifies the user using any notification daemon implementing org.freedesktop.Notifications.

Salut is a link-local XMPP (XEP-0174) connection manager for the Telepathy framework, currently supporting presence and single-user chats with iChat interoperability, and multi-user chats and Tubes using the Clique protocol.

Displaying and dumping information on Direct Rendering Manager devices.

Telepathy Mission Control 5 is an account manager and channel dispatcher for the Telepathy framework, allowing user interfaces and other clients to share connections to real-time communication services without conflicting.

Elogind is the systemd project's "logind" service, extracted out as a separate project. Elogind integrates with PAM to provide the org.freedesktop.login1 interface over the system bus, allowing other parts of a the system to know what users are logged in, and where.

The AccountService project provides a set of D-Bus interfaces for querying and manipulating user account information and an implementation of these interfaces, based on the useradd, usermod and userdel commands.

Telepathy logger is a headless observer client that logs information received by the Telepathy framework. It features pluggable backends to log different sorts of messages in different formats.

This is a GTK convenience library for interacting with colord. It is useful for both applications which need colour management and applications that wish to perform colour calibration.

PyXDG is a collection of implementations of freedesktop.org standards in Python.

This package provides wayland-info tool that can be used to check which Wayland protocols and versions are advertised by the Wayland compositor.
