DRM_CLIENT_CAP_STEREO_3D(9)

💅 DRM_CLIENT_CAP_STEREO_3D — Kernel API Manual 💅

okay bestie, welcome to the tiny little manpage that's lowkey about making your screen go 👓 3D. it's short, it's sweet, and the manual name is literally DRM_CLIENT_CAP_STEREO_3D(9) so like… yeah. let's get into it 🫶

---

✨ NAME ✨

DRM_CLIENT_CAP_STEREO_3D — that's it. that's the name. no description given, she's mysterious like that 🙈 (the original page leaves the description blank, so we're honoring that, periodt)

---

🌸 SYNOPSIS 🌸

DRM_CLIENT_CAP_STEREO_3D

just the flag itself, standing there, being iconic. no arguments, no nothing ✨

---

🎀 DESCRIPTION 🎀

okay so here's the tea ☕ — if you set this bad boy to 1, the DRM core will expose the stereo 3D capabilities of the monitor by advertising the supported 3D layouts in the flags of struct drm_mode_modeinfo. the way that works is you go look at DRM_MODE_FLAG_3D_* and all your 3D layout dreams are right there in the flags 🔥

the way that…" it's giving "monitor said 'i do 3D' and the kernel said 'bet'" 💀

and the best part? this capability is always supported for all drivers starting from kernel version 3.13 🎉 no cap, no caveats, no "it depends" — from 3.13 onwards it's just there for every driver. slay 👑
