Came to this bug while searching on my the wireless toggle switch doesn't work on my Thinkpad X1 Carbon after a fresh Ubuntu 14.10 install. I understand some of the reasoning above, which seems to say, that it is not really an issue because the button press can be intercepted through other ways and dealt with then, but I want to say that is the only key that is not working out of the box, so it is really confusing, and just plain bad user experience. Even after reading the "solution" above, I can't get it to work on my laptop. I can use rfkill command for now, but, oh boy, it would be great to the key properly working.
It appears that the code in charge of handling the X1 Carbon adaptive keyboard is here and rfkill handling is there: https://kernel.googlesource.com/pub/scm/linux/kernel/git/jic23/iio/+/refs/heads/togreg/drivers/platform/x86/thinkpad_acpi.c So, it's either my stock kernel doesn't have it, or something else is broken. Here's some info about your system. root@x1:~# cat /proc/cmdline BOOT_IMAGE=/vmlinuz-3.16.0-24-generic.efi.signed root=/dev/mapper/ubuntu--vg-root ro quiet splash acpi_osi=Linux acpi_enforce_resources=lax i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 i915.semaphores=1 vt.handoff=7 root@x1:~# uname -r 3.16.0-24-generic root@x1:~# ls /dev/input/by-path/platform-thinkpad_acpi-event -lh lrwxrwxrwx 1 root root 9 Nov 2 19:45 /dev/input/by-path/platform-thinkpad_acpi-event -> ../event7 # nothing ever fires when I press all extra buttons including the wireless one root@x1:~# input-events 7 /dev/input/event7 bustype : BUS_HOST vendor : 0x17aa product : 0x5054 version : 16641 name : "ThinkPad Extra Buttons" phys : "thinkpad_acpi/input0" bits ev : EV_SYN EV_KEY EV_MSC EV_SW waiting for events timeout, quitting # acpi events fire for all extra buttons except the wireless one! root@x1:~# acpi_listen -t 100 ibm/hotkey LEN0068:00 00000080 00001105 ibm/hotkey LEN0068:00 00000080 00001106 ibm/hotkey LEN0068:00 00000080 00001108 ibm/hotkey LEN0068:00 00000080 0000110a ibm/hotkey LEN0068:00 00000080 00001101 ibm/hotkey LEN0068:00 00000080 00001101 ibm/hotkey LEN0068:00 00000080 00001101 video/switchmode VMOD 00000080 00000000 ibm/hotkey LEN0068:00 00000080 0000110e So, since nothing fires on both channels, it seems I can't manually bind the button to rfkill either. Please tell me what I can do to help. -- 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: 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.
