Title:
  [Lenovo Thinkpad X220] wireless switch doesn't generate an acpi event

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  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
