GTF(1)

✨ NAME ✨

gtf — bestie, this is the little icon that calculates VESA GTF mode lines for you 💅

---

🌸 SYNOPSIS 🌸

gtf h-resolution v-resolution refresh [-v|--verbose] [-f|--fbmode]
[-x|--xorgmode]

---

🎀 DESCRIPTION 🎀

okay so gtf is a utility for calculating VESA GTF modes. you hand it the horizontal resolution, the vertical resolution and the refresh rate (in Hz) you're dreaming of, and it prints out the parameters for a matching VESA GTF mode. that's it. that's the whole girlboss move ✨

it supports two output formats, and this is the part where you pick your fighter:

• mode lines suitable for the Xorg xorg.conf(5) file 📄
• mode parameters suitable for the Linux fbset(8) utility 🐧

---

💖 OPTIONS 💖

• -v, --verbose — turns on verbose printouts. this shows a trace for each step of the computation, so you can watch the math do its little dance step by step 👑
• -x, --xorgmode — prints the mode parameters as Xorg-style mode lines. heads up: this is the default format, so if you do nothing, this is what you get 🫶
• -f, --fbset — prints the mode parameters in a format suitable for fbset(8) 🍓

tiny heads-up bestie: in the synopsis up top the long form of -f is written --fbmode, and down here in the options it's --fbset. i am simply the messenger, i do not make the rules 🙈 i'm reproducing both exactly as they are, no cap.
