XForms is a graphical user interface toolkit for X based on the X11 Xlib library. It allows you to create windows, containing all kinds of widgets (buttons, sliders, browsers, menus etc.) with a few lines of code and then attach actions to the widgets, i.e., have some function called when a button is pressed. To make this even easier XForms comes with a program called fdesign that allows you to design a GUI for a program directly on the screen and which then writes out the necessary C code for it.

xsettingsd is a lightweight daemon that provides settings to Xorg applications via the XSETTINGS specification. It is used for defining font and theme settings when a complete desktop environment (GNOME, KDE) is not running. With a simple .xsettingsd configuration file one can avoid configuring visual settings in different UI toolkits separately.

The hsetroot command composes wallpapers for X. This package is the fork of hsetroot by Hyriand.

The xf86-input-wacom driver is the wacom-specific X11 input driver for the X.Org X Server version 1.7 and later (X11R7.5 or later).

xsecurelock is an X11 screen locker which uses a modular design to avoid the usual pitfalls of screen locking utility design.

As a consequence of this design, you shouldn't use the usual screen locker service with xsecurelock. Instead, add a helper binary to your operating-system's privileged-programs field:

(privileged-programs
 (cons*
  (privileged-program
   (program (file-append xsecurelock "/libexec/xsecurelock/authproto_pam"))
   (setuid? #t))
  %default-privileged-programs))

Wl-clipboard is a set of command-line copy/paste utilities for Wayland.

Hyprpaper is a blazing fast wallpaper utility for Hyprland with the ability to dynamically change wallpapers through sockets. It will work on all wlroots-based compositors, though.

Wlsunset adjusts gamma based on day-night cycles on Wayland compositors that support wlr-gamma-control-unstable-v1. It is also known as a blue light filter or night light.

Xeyes is a demo program for x.org. It shows eyes following the mouse.

kbdd is a simple keyboard layout switching program, which is designed to run in an X11 session and remember keyboard layouts on a per-window basis. That can be very handy for a user of a non-US keyboard who does not want to jump through layouts back and forth while typing in terminals (mostly in a latin alphabet) and some kind of chat (in native language).

kbdd also supports D-Bus signals, which makes it possible to create layout indicator widgets.

This is a small utility to provide a blue light filter for your system. This method is preferred to screen shaders as it will not be captured via recording / screenshots.

hyprsunset also provides a gamma filter, which can be used to adjust perceived display brightness on monitors that do not support software control, or to reduce percieved brightness below the monitor's minimum.

GNU Xnee is a program that can record, replay and distribute user actions in X11. It can be used to automate user interactions for testing or demonstration purposes.

Xautolock monitors input devices under the X Window System, and launches a program of your choice if there is no activity after a user-configurable period of time.

xssproxy implements the org.freedesktop.ScreenSaver D-Bus interface described in the Idle Inhibition Service Draft by the freedesktop.org developers. The inhibition of the screensaver is then controlled using the XScreenSaverSuspend function from the Xss (X11 Screen Saver extension) library.

xscreensaver is a popular screen saver collection with many entertaining demos. It also acts as a nice screen locker.

Stalonetray is a stand-alone freedesktop.org and KDE system tray (notification area) for X Window System/X11 (e.g. X.Org or XFree86). It has full XEMBED support and minimal dependencies: an X11 lib only. Stalonetray works with virtually any EWMH-compliant window manager.

Pixman is a low-level software library for pixel manipulation, providing features such as image compositing and trapezoid rasterisation.

nxbelld is a tiny utility to aid people who either don't like the default PC speaker beep, or use a sound driver that doesn't have support for the PC speaker. The utility performs a given action every time the X bell is rung. The actions nxbelld can currently perform include running a specified program, emulating the PC speaker beep using the sound card (default), or playing a PCM encoded WAVE file.

FYI is a command line utility to send desktop notifications to the user via a notification daemon implementing XDG desktop notifications.

Rxvt-unicode (urxvt) is a colour vt102 terminal emulator intended as an xterm replacement for users who do not require features such as Tektronix 4014 emulation and toolkit-style configurability. It supports unicode, XFT and may be extended with Perl plugins. It also comes with a client/daemon pair that lets you open any number of terminal windows from within a single process.

The xwallpaper utility allows you to set image files as your X wallpaper. JPEG, PNG, and XPM file formats are supported.

The wallpaper is also advertised to programs which support semi-transparent backgrounds.

Xclip is a command line interface to the X11 clipboard. It can also be used for copying files, as an alternative to sftp/scp, thus avoiding password prompts when X11 forwarding has already been setup.

Gammastep automatically adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night.

Wofi is a launcher/menu program for wlroots based wayland compositors such as sway, similar to rofi.
