The shared-mime-info package contains the core database of common types and the update-mime-database command used to extend it. It requires glib2 to be installed for building the update command. Additionally, it uses intltool for translations, though this is only a dependency for the maintainers. This database is translated at Transifex.

MalContent implements parental controls support which can be used by applications to filter or limit the access of child accounts to inappropriate content.

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.

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.

Exempi is an implementation of the Extensible Metadata Platform (XMP), which enables embedding metadata in PDF and image formats.

Wtype lets you simulate keyboard input and mouse activity, move and resize windows, etc.

Snixembed is a program to proxy StatusNotifierItems as XEmbedded systemtray-spec icons. This allows programs that only support the newer StatusNotifierItem to have the older XEmbedded systemtray support. While snixembed works fine with most setups, some bars and DEs provide their own optional SNI support, which should be preferred when available.

Currently supported:

• icons (by pixmap and by freedesktop name)

• activation on left mouse button

• context menu on right mouse button (Menu dbusmenu or ContextMenu)

• tooltips (on hover, all markup except hyperlinks)

• limited AppIndicator support as a fallback

uchardet is an encoding detector library, which takes a sequence of bytes in an unknown character encoding without any additional information, and attempts to determine the encoding of the text. Returned encoding names are iconv-compatible.

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.

The xdg-utils package is a set of simple scripts that provide basic desktop integration functions in the framework of the freedesktop.org project.

This package provides a straightforward implementation of the XDG Base Directory Specification.

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

xdg-user-dirs is a tool to help manage "well known" user directories, such as the desktop folder or the music folder. It also handles localization (i.e. translation) of the file names. Designed to be automatically run when a user logs in, xdg-user-dirs can also be run manually by a user.

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.

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

Wayland is a project to define a protocol for a compositor to talk to its clients as well as a library implementation of the protocol. The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a wayland client itself. The clients can be traditional applications, X servers (rootless or fullscreen) or other display servers.

AppStream is a cross-distribution effort for enhancing the way we interact with the software repositories provided by distributions by standardizing software component metadata. It provides the foundation to build software-center applications, by providing metadata necessary for an application-centric view on package repositories. It additionally provides specifications for things like an unified software metadata database, screenshot services and various other things needed to create user-friendly application-centers for distributions.

This package provides an xdg-desktop-portal backend for Hyprland.

Libmbim is a GLib-based library for talking to WWAN modems and devices which speak the Mobile Interface Broadband Model (MBIM) protocol.

This package provides C++ bindings for the Wayland display protocol.

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

Libliftoff eases the use of KMS planes from userspace. Users create "virtual planes" called layers, set KMS properties on them, and libliftoff will pick hardware planes for these layers if possible.

This package provides xdg-desktop-portal-wlr. This project seeks to add support for the screenshot, screencast, and possibly remote-desktop xdg-desktop-portal interfaces for wlroots based compositors.

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.
