💖 GDDCCONTROL 💖

okay bestie, so this is the manual for gddccontrol — that's a General Commands Manual situation, one command, and it's here to let you talk to your monitor with software instead of angrily mashing the physical buttons. we're obsessed.

✨ NAME ✨

gddccontrol — a graphical utility to control monitor parameters via software 🖥️🦋

✨ SYNOPSIS ✨

gddccontrol [options]

that's it. that's the whole vibe. you run it, you pass it some options, it does its thing. periodt. 💅

✨ DESCRIPTION ✨

so this manual page documents briefly the gddccontrol command. brief, but cute.

gddccontrol is an open source utility which allows controlling monitor parameters via software. that's the whole main character energy of it — your monitor settings, handled in software, no cap. 🌈

✨ OPTIONS ✨

okay so real talk: as a GTK3 application, gddccontrol accepts the standard GTK3 options. yes, all the GTK3 ones. it's giving inherited behavior, and we respect it. 👑

then there's these two of its own:

  • --hide-unsupported-warning — Do not show the warning banner for unsupported monitors when a fallback profile is used. basically: if your monitor isn't officially supported and it's falling back to a profile anyway, this yeets the warning banner so it stops yelling at you. 🙈
  • -v, --verbose — Increase verbosity. Repeat (e.g. -vv) for more detailed output. one -v is like "tell me a lil more", and stacking them is like "bestie give me EVERYTHING". 🔥

✨ ENVIRONMENT ✨

two env vars, both iconic, both listed here:

  • DDCCONTROL_NO_DAEMON — When set to a non-empty value, gddccontrol bypasses the D-Bus daemon and accesses /dev/i2c-* devices directly. This can be useful for testing, debugging, or working around a daemon startup or connection problem. so like, if the daemon is being dramatic and won't start or won't connect, this is your escape hatch. 🫶
  • GTK_THEME — Override the GTK theme for this launch. For example, run GTK_THEME=HighContrastInverse gddccontrol to use the GTK high-contrast dark theme when it is installed. If running through sudo, use sudo env GTK_THEME=HighContrastInverse gddccontrol. yes, the env is doing heavy lifting there — sudo does NOT pass your theme through on its own, and the example is right there showing you the move. 🌸
ngl, that sudo env ... line is the kind of detail that saves you twenty minutes of "why is my theme not applying" spiraling. iykyk. 💀
