Tobias Stegmann, could you please test the latest upstream kernel available (the one all the way at the top, and not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-3.15-rc8 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-1.39 ** Changed in: linux (Ubuntu) Importance: Low => Medium ** Summary changed: - Thinkpad X220 wireless switch doesn't generate an acpi event + [Lenovo Thinkpad X220] wireless switch doesn't generate an acpi event -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1310248 Title: [Lenovo Thinkpad X220] wireless switch doesn't generate an acpi event Status in “linux” package in Ubuntu: Incomplete 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.
