IGMAFB(4)

📦 version 11.0, in nixpkgs unstable

💖 IGMAFB(4) — Intel Graphics Media Accelerator framebuffer driver 💖

okay so bestie, welcome to section 4 of the Kernel Interfaces Manual — this is the igmafb page and it's literally about making your Intel integrated graphics actually show you a screen ✨

🎀 SYNOPSIS 🎀

options VGA_RASTERCONSOLE
no options VGA_POST
no agp
no device at drm
no genfb
igma0 at pci0 dev ? function ?
igmafb* at igma0
iic* at igma0

ngl, that last block is the whole personality of this page — it's giving "I need the entire stage to myself" 👑

🌸 DESCRIPTION 🌸

so igmafb is the driver that brings support for the integrated graphics functions in Intel chipsets, and it hands you an interface to the machine independent wscons(4) driver 🫶 like, it's the middleman between your fancy Intel silicon and the console system you actually see.

Right now, igmafb configures the display for the integrated panel in notebooks and can control the backlight 💡 — cute, useful, does the thing.

Automatic detection of the main display on desktop machines may or may not work 🙈 (yes, that's the actual energy — it's a coin flip, no cap).

The supported hardware includes:

  • GMA 900 (915G)
  • GMA 950 (945G)
  • GMA 3000 (Q965)
  • GMA X3000 (G965)
  • GMA X3500 (G35)
  • GMA X4500 (G45)
  • HD (Westmere)
  • HD2000/3000 (Sandy Bridge)
  • HD2500/4000 (Ivy Bridge)

iconic lineup honestly, a whole era of chips living their best life in this list 👑

The igmafb driver was written by Michael van Elst — ty for your service, king 🫡✨

💀 BUGS 💀

  • The driver conflicts with genfb(4), agp(4), and thus with drm(4) 😭 — that's why the SYNOPSIS is full of no lines, it's not being dramatic, it genuinely can't share the sandbox.
  • Support for a hardware cursor is missing 💔 no cursor for you bestie, mourn it.

so that's the whole page — igmafb, section 4, straight outta Debian, dated January 21, 2014 🎀 tysm for reading, go check your backlight settings and slay 💖
