DMX(3)

💅 DMX(3) — the vibe check

okay bestie, listen. you're looking at the manual page for DMX(3), from the Library Functions Manual, and honestly? it's giving main character energy for your whole multihead setup. let's get into it 🫶

---

✨ NAME ✨

DMX — the X Window System DMX extension. that's Distributed Multihead X, and yes, the acronym is the whole personality 💜

---

🌈 DESCRIPTION 🌈

so here's the tea: the DMX extension is literally the support system that lets you communicate with and control the Xdmx(1) server. that's it. that's the job.

and it's not just vibes — you can query and modify all of this through the protocol:

• the attributes of the Xdmx(1) server itself 👑
• the attributes of the back-end screens attached to that server 🖥️🖥️🖥️

so yeah, you get to peek at stuff and change stuff. iconic behaviour, no notes. ✨
