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.

fuzzel is a Wayland-native application launcher, similar to rofi's drun mode. It has Emacs key bindings and remembers frequently launched applications. The font and colors can be configured.

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.

This is a fork with added support for Wayland using the wlr-gamma-control protocol.

wlrctl is a command line utility for miscellaneous wlroots Wayland extensions. At this time, wlrctl supports the foreign-toplevel-mangement (window/toplevel command), virtual-keyboard (keyboard command), and virtual-pointer (pointer command) protocols.

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.

maim (Make Image) is a tool that takes screenshots of your desktop and saves it in any format. Along with a full screen, it allows you to capture a predefined region or a particular window. Also, it makes it possible to include cursor in the resulting image.

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

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.

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))

Start clipmenud, then run clipmenu to select something to put on the clipboard.

When clipmenud detects changes to the clipboard contents, it writes them out to the cache directory. clipmenu reads the cache directory to find all available clips and launches dmenu (or rofi, depending on the value of CM_LAUNCHER) to let the user select a clip. After selection, the clip is put onto the PRIMARY and CLIPBOARD X selections.

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

xss-lock listens to X signals to fire up a user-defined screensaver. In effect this automatically locks the screen when closing a laptop lid or after a period of user inactivity (as set with xset s TIMEOUT). The notifier command, if specified, is executed first. Additionally, xss-lock uses the inhibition logic to lock the screen before the system goes to sleep.

XLockMore is a classic screen locker and screen saver for the X Window System.

This package provides an application grid, button bar, and dmenu applications for Sway and other wlroots-based Wayland compositors.

The Direct Rendering Infrastructure, also known as the DRI, is a framework for allowing direct access to graphics hardware under the X Window System in a safe and efficient manner. It includes changes to the X server, to several client libraries, and to the kernel (DRM, Direct Rendering Manager). The most important use for the DRI is to create fast OpenGL implementations providing hardware acceleration for Mesa. Several 3D accelerated drivers have been written to the DRI specification, including drivers for chipsets produced by 3DFX, AMD (formerly ATI), Intel and Matrox.

This package provides a library for programmatically controlling Xorg windows using Python. The library relies on the wmctrl to do so.

physlock locks all virtual terminals at once, only allowing the user of the active session (the user logged into the foreground virtual terminal) to unlock the computer. It is an alternative to vlock -an, written to overcome vlock's limitations regarding hibernate and suspend.

Xkeysnail is an X environment keyboard remapping tool, featuring high-level and flexible remapping mechanisms. It affects the low-level layers (evdev and uinput), making remapping work in almost all the places.

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.

This package provides a small utility for inverting the colors on all monitors attached to an XRandR-capable X11 display server.

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.

This library implements cross-platform clipboard utilities supporting both binary and text data.

Startup-notification contains a reference implementation of the startup notification protocol. The reference implementation is mostly under an X Window System style license, and has no special dependencies.

Bind a key for any given application that will launch the application, if it's not already running, or focus the application's window,if it is running. Pressing the key again will cycle to the application's next window, if there's more than one.
