XGAMMA(1)

✨ XGAMMA(1) ✨

okay so bestie, welcome to the xgamma page 💖 this one's from X Version 11 and honestly? it's giving retro vibes but also a little "why is this still here" energy. let's get into it 🎀

---

🌸 NAME 🌸

xgamma — alter a monitor's gamma correction through the X server, no cap

---

🦋 SYNOPSIS 🦋

xgamma [-display display] [-screen screen] [-quiet] [-help|-version]
       [-gamma f.f | [[-rgamma f.f] [-ggamma f.f] [-bgamma f.f]]]

like, that's the whole vibe. flags on flags on flags 💅

---

🌈 DESCRIPTION 🌈

so xgamma lets X users query and alter the gamma correction of a monitor, and it does this via the X video mode extension, aka the XFree86-VidModeExtension. iconic name, i know ✨

⚠️ okay important heads up bestie: the xgamma utility is obsolete and deficient. like, it's not the main character anymore 😭 you should use xrandr(1) with drivers that support the XRandr extension instead. fr fr.

and here's the cute part: if you don't give it any gamma correction value via the -gamma or -rgamma/-ggamma/-bgamma options, xgamma just prints the current gamma correction of the display. like a little vibe check for your monitor 🫶

💅 OPTIONS 💅

• -display display — lets you specify the server to connect to; see X(7) for the deets 👀
• -screen screen — when multiple displays are configured as a single logical display, this lets you pick which screen you wanna change. choose your fighter 🎀
• -quiet — shuts up the normal output of xgamma. silence is golden, periodt 💀
• -help — prints out the Usage: command syntax summary. a little cheat sheet, we love that
• -version — prints out the program version and dips. bye bestie 👋
• -gamma f.f — the gamma correction can be defined as a single value, OR separately for the red, green and blue components. this one specifies it as a single value ⭐
• -rgamma f.f — specifies the red component of the gamma correction 🔥
• -ggamma f.f — specifies the green component of the gamma correction 🌿
• -bgamma f.f — specifies the blue component of the gamma correction 🦋

---

🧚 ENVIRONMENT 🧚

• DISPLAY — to get default host and display number. it's giving "where am i supposed to be" energy 🌸

---

💀 BUGS 💀

okay so not everything is slay here, listen up:

• this client changes the internal values of the gamma correction for the Xserver. whether or not these values are actually respected depends on the video drivers. so like, no promises bestie 🙈
• the gamma values are passed to the Xserver with 3 decimal places of accuracy. that's it. that's the precision. don't come for me 😭
