💖 fluxcore(6) 💖

okay so first things first: this is a page from the XScreenSaver manual — yes that XScreenSaver, the one that's been making your screen pretty since before you were born. fluxcore is one of its savers and honestly? it's giving main character energy. ✨

🦋 NAME 🦋

fluxcore — it's a screen saver, bestie. that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

fluxcore [--display host:display.screen] [--visual visual] [--window]
[--root] [--delay number] [--speed number] [--scale number] [--fps]

run it, pass it some flags, watch the pretty energy happen. no cap. 🔥

✨ DESCRIPTION ✨

okay so the lore is actually iconic: long range space-based energy transmission requires a flux core to amplify and concentrate energy. that's it. that's the whole thing. a flux core. in space. transmitting energy. over long range. 🛰️💫

so basically this saver is a whole sci-fi power source just vibing on your monitor and i am obsessed. 🫶

🎀 OPTIONS 🎀

  • --visual visual — picks which visual to use. legal values are either the name of a visual class, or the id number of one specific visual (and yes, decimal or hex both work, we're flexible like that 💅).
  • --window — draw on a newly-created window. this is the default, so it's already what you're getting unless you say otherwise. ✨
  • --root — draw on the root window instead. full-screen chaos era. 🖥️
  • --delay number — per-frame delay, measured in microseconds. default is 20000, which is 0.02 seconds for anyone who doesn't do micro-math in their head. ⏱️
  • --speed number — animation speed multiplier. 2.0 means twice as fast, 0.5 means half as fast. choose your own adventure. 🏃‍♀️💨
  • --scale number — frame buffer resolution. 0.5 halves the resolution for better performance but lower quality output. default is 1.0, full quality. no compromise behavior, love that for you. 🌈
  • --fps | --no-fps — whether to show a frames-per-second display down at the bottom of the screen. yes or no, your call, no wrong answers. 📊

🧚 ENVIRONMENT 🧚

  • DISPLAY — used to get the default host and display number. the classic. 👑
  • XENVIRONMENT — used to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. fancy override energy. 🎀
  • XSCREENSAVER_WINDOW — the window ID to use with --root. ikyk. 💜
