RADEONTOOL(8)

🎀 RADEONTOOL 💅

okay so bestie, welcome to the radeontool page — it lives in the System Manager's Manual section 8, which is the "admin stuff" corner of the manual world, iykyk. grab a strawberry 🍓 and let's get into it.

✨ NAME ✨

radeontool — the little utility that gets/sets registers and controls the backlight on radeon based laptops 🦋

🌸 SYNOPSIS 🌸

radeontool [option] [command]

💖 DESCRIPTION 💖

This manual page documents briefly the radeontool command. Short and sweet, no cap.

This manual page was written for the Debian distribution because the original program does not have a manual page. not me being the replacement bestie 😭 — but fr fr, that's the whole reason this page exists.

So what does radeontool actually do? It's a program that switches on/off the backlight and the external output on ATI Radeon based laptops, and it's also able to list or set register values. it's giving tiny utility, main character energy 👑

⭐ COMMANDS ⭐

You can specify one of the following commands. one. singular. pick your fighter 💅

• dac [on|off] — powers down the external video output 🔌
• light [on|off] — powers down the backlight 🌙 (yes this is the one everyone actually came here for)
• stretch [on|off|vert|horiz|auto|manual] — adjusts stretching for resolution mismatch 📐
• regs — shows a listing of some random registers 🎲 (yes, "random" is doing a lot of work in that sentence, that's literally what the page says)
• regmatch [pattern] — shows registers matching the wildcard pattern 🔍
• regset [pattern] [value] — sets registers matching the wildcard pattern 🛠️

💅 OPTIONS 💅

These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-`). A summary of options is included below, periodt.

• --debug — show a little debug info 🐛 (just a little. a sprinkle.)
• --skip=n — skips the first n cards and acts on the n+1 🃏 (so if you've got a whole stack of cards and you want the second one, that's --skip=1, bestie)

ngl bestie, if you're poking at registers with regset, be careful — you're writing straight into hardware, and the page doesn't promise it'll be nice about it. vibes only on the commands you understand 🫶

and that's the whole page!! 💖 thanks for reading RADEONTOOL(8) with me, mwah, see you in the next man page 🌈✨
