ibm-acpi - IBM ThinkPad ACPI Extras Driver

This is a Linux ACPI driver for the IBM ThinkPad laptops written by Borislav Deianov. It aims to support various features of these laptops which are accessible through the ACPI framework but not otherwise supported by the generic Linux ACPI drivers. As a kernel module, ibm-acpi works as a bridge to deliver information about certain hardware events like key presses or control the state of certain hardware features by software.

Features

  • triggers ACPI Events for
    • Fn key combinations (FnF1, FnF2, FnF3, FnF4, FnF5, FnF6, FnF7, FnF8, FnF9, FnF10, FnF11, FnF12)
    • UltraBay device eject
    • Display lid, Power button, Undock button
  • enables software control of
    • Bluetooth
    • Video output switching, video expansion control
    • Docking and undocking (limited)
    • Fan (on most models, only enable/disable; speed control is added by a further patch)
    • Volume
    • LCD Brightness
    • ThinkLight
    • LEDs
    • Beep codes
    • Several CMOS states
  • can show values of


Some of these features are available only when the module is loaded with the experimental=1 option. To enable it, add the following to /etc/modprobe.conf (or your distribution's equivalent):

options ibm_acpi experimental=1
