Title: [Lenovo Thinkpad X220] wireless switch doesn't generate an acpi event Status in “linux” package in Ubuntu: Triaged Bug description: $ lsb_release -rd Description: Ubuntu 14.04 LTS Release: 14.04 I use a customized acpi event script to disable bluetooth on my Thinkpad x220, if I toggle the hardware wifi switch (not Fn+F5): $ cat /etc/acpi/ibm-wireless-switch.sh #!/bin/sh test -f /usr/share/acpi-support/state-funcs || exit 0 # Find and toggle wireless of bluetooth devices on ThinkPads . /usr/share/acpi-support/state-funcs # disable bluetooth on wireless activate to save battery if isAnyWirelessPoweredOn; then # Wireless was turned on logger "Wireless switch turned on: Disable bluetooth." echo disable > /proc/acpi/ibm/bluetooth fi This used to work fine with Ubuntu 13.10, however it stopped working with 14.04. More precisely the switch doesnt generate an acpi event anymore. To check that I used acpi_listen. $ acpi_listen -t 10 # nothing happens here Using 14.04 with kernel version 3.11.0-19 from 13.10 the switch works fine again: $ acpi_listen -t 10 ibm/hotkey HKEY 00000080 00007000 Thanks. --- ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: tobias 2256 F.... pulseaudio tobias 2324 F.... pulseaudio CurrentDesktop: KDE DistroRelease: Ubuntu 14.04 InstallationDate: Installed on 2013-03-24 (438 days ago) InstallationMedia: Kubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.1) Lsusb: Bus 002 Device 002: ID 8087:0024 Intel Corp.
