💖 xscreensaver-gl-visual 💖

okay so bestie, this is the xscreensaver-gl-visual page from the XScreenSaver manual, section 1, and it is short but it is doing something kinda iconic. it's the little helper that goes "hey, THIS visual, use THIS one" so your GL stuff doesn't freak out. let's get into it 🦋

✨ NAME ✨

xscreensaver-gl-visual — figure out which X visual to use for GL programs

like. that's the whole job. it figures out the visual. that's it. and yet. 👑

✨ SYNOPSIS ✨

xscreensaver-gl-visual [--display host:display.screen]
  • --display host:display.screen — tell it which display to look at, in the classic host:display.screen format. same energy as everywhere else in X-land, iykyk 💅

✨ DESCRIPTION ✨

so what does this tiny main character actually do? it prints out the ID of the visual that should be used for proper operation of OpenGL programs. that's the tea. 🍓

and why does a whole separate binary exist for one (1) print statement, you ask? because the xscreensaver(1) daemon did NOT want to link against the OpenGL library, periodt. so this lil guy gets its own program, does the one thing, and everybody stays unlinked. no cap, it's giving separation of concerns. 🧚

✨ ENVIRONMENT ✨

  • DISPLAY — used to get the default host, display, and screen number. if you don't pass --display, this is where it looks. 🌈

✨ SEE ALSO ✨

go read those too, they're the friend group 💜
