decayscreen(6x)

🌸 NAME 🌸

Okay bestie, meet decayscreen — this is the decayscreen(6x) page from the XScreenSaver manual, and its whole personality is literally to make a screen meltdown. Iconic, chaotic, we love it. 💖

---

✨ SYNOPSIS ✨

Run it like this, no cap:

decayscreen [--display host:display.screen] [--window] [--root]
            [--window-id number] [--mono] [--install] [--visual visual]
            [--delay usecs] [--duration secs] [--mode mode] [--fps]

---

🦋 DESCRIPTION 🦋

The decayscreen program creates a melting effect by randomly shifting rectangles around the screen. Rectangles, but make it sliding chaos. It’s giving controlled meltdown and honestly it ate. 💅

The image that it manipulates will be grabbed from the portion of the screen underlying the window, or from the system's video input, or from a random file on disk, as indicated by the grabDesktopImages, grabVideoFrames, and chooseRandomImages options in the ~/.xscreensaver file; see xscreensaver-settings(1) for more details. So yeah, your source pic gets chosen by those config options, and the full tea lives in that other manpage. 🫶

💅 OPTIONS 💅

decayscreen accepts the following options:

• --window — Draw on a newly-created window. This is the default. Default alert! ✨
• --root — Draw on the root window. Root window vibes.
• --window-id number — Draw on the specified window.
• --mono — If on a color display, pretend we're on a monochrome display. Delulu but monochrome. 💀
• --install — Install a private colormap for the window.
• --visual visual — Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. Decimal or hex, bestie.
• --delay microseconds — Slow it down. Chill mode activated.
• --duration seconds — How long to run before loading a new image. Default 120 seconds. Yes, 120 seconds, exactly.
• --mode mode — The direction in which the image should tend to slide. Legal values are:
  • random — meaning pick one
  • up
  • left
  • right
  • down
  • upleft
  • downleft
  • upright
  • downright
  • shuffle — meaning prefer no particular direction
  • in — meaning move things toward the center
  • out — meaning move things away from the center
  • melt — meaning melt straight downward
  • stretch — meaning stretch the screen downward
  • fuzz — meaning go blurry instead of melty
• --fps — Display the current frame rate and CPU load. Numbers go brrr. 🔥

🌈 ENVIRONMENT 🌈

• DISPLAY — to get the default host and display number.
• XENVIRONMENT — to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
• XSCREENSAVER_WINDOW — The window ID to use with --root. Root mode helper!
