The x-resize command detects physical display resolution changes via udev and invokes the xrandr command to reconfigure the active display resolution accordingly. It can be used to implement dynamic resize support for desktop environments that lack native support such as Xfce.

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

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.

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))

This package provides a wlroots-compatible Wayland color picker.

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.

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.

xtrlock locks the X server till the user enters their password at the keyboard. While xtrlock is running, the mouse and keyboard are grabbed and the mouse cursor becomes a padlock. Output displayed by X programs, and windows put up by new X clients, continue to be visible, and any new output is displayed normally. The mouse and keyboard are returned when the user types their password, followed by Enter or Newline. If an incorrect password is entered the bell is sounded. Pressing Backspace or Delete erases one character of a password partially typed; pressing Escape or Clear clears anything that has been entered.

xwhite is a command line tool for adjusting the colour balance of screen. It is based on xrandr's gamma correction and brightness adjustment. As such, it can only be used for X displays and not Wayland displays. It is typically used for tuning the color balance and color temperature. It has a similar function as redshift -P -g R:G:B -O temperature, but xwhite is more flexible in that it does not keep the white color fixed, suitable for setting the white color to an arbitrary balanced color.

numlockx is a tiny program that lets you turn on the numlock key in X11. It can be called from the user's initialization files to automatically turn it on on login.

AutoKey is a desktop automation utility for X11. It allows the automation of virtually any task by responding to typed abbreviations and hotkeys. It offers a full-featured GUI (GTK and QT versions) that makes it highly accessible for novices, as well as a scripting interface offering the full flexibility and power of the Python language.

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.

rofi-calc is a rofi plugin that uses qalculate's qalc to parse natural language input and provide results.

screen-message is a tool for displaying text on your screen. It will make the text as large as possible and display it with black color on a white background (colors are configurable on the commandline).

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.

Mtdev is a stand-alone library which transforms all variants of kernel MT events to the slotted type B protocol. The events put into mtdev may be from any MT device, specifically type A without contact tracking, type A with contact tracking, or type B with contact tracking.

Redshift adjusts the color temperature according to the position of the sun. A different color temperature is set during night and daytime. During twilight and early morning, the color temperature transitions smoothly from night to daytime temperature to allow your eyes to slowly adapt. At night the color temperature should be set to match the lamps in your room.

Rofi is a minimalist application launcher. It memorizes which applications you regularly use and also allows you to search for an application by name.

sxhkd is a simple X hotkey daemon with a powerful and compact configuration syntax.

dex, DesktopEntry Execution, is a program to generate and execute .desktop files of the Application type. It is also an autostarter compliant with the XDG autostart specification.

xiccd provides color profile support for desktop environments other than GNOME and KDE. It does the following tasks:

• Enumerates displays and register them in colord.

• Creates default ICC profiles based on EDID data.

• Applies ICC profiles provided by colord.

• Maintains user's private ICC storage directory.

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.

Autorandr wraps around xrandr to help with X11 multi-screen configuration management. It allows the user to create profiles for various multi-screen setups. Autorandr automatically detects the profiles that can be activated based on the connected hardware. Hook scripts can be used to further tweak the behaviour of the different profiles.

If arguments are given, xtitle outputs the title of each specified window, otherwise it outputs the title of the active window. With snoop mode on, it continuously monitors the specified windows and outputs when titles change.
