[Bug 1310248] Re: [Lenovo Thinkpad X220] wireless switch doesn't generate an acpi event
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 0080 1105 ibm/hotkey LEN0068:00 0080 1106 ibm/hotkey LEN0068:00 0080 1108 ibm/hotkey LEN0068:00 0080 110a ibm/hotkey LEN0068:00 0080 1101 ibm/hotkey LEN0068:00 0080 1101 ibm/hotkey LEN0068:00 0080 1101 video/switchmode VMOD 0080 ibm/hotkey LEN0068:00 0080 110e So, since nothing fires on both channels, it seems I can't manually bind the button to rfkill either.

[Bug 1310248] Re: [Lenovo Thinkpad X220] wireless switch doesn't generate an acpi event
Here's the awnser of the thinkpad_acpi module maintainer: https://www
.mail-archive.com/platform-driver-x86@vger.kernel.org/msg05285.html
To summarize: The patch itself is technically correct and leads to the
old behaviour. But he'd prefer not to apply the patch, because the event
is already propagated through the thinkpad_acpi input device.
The input device is located at /dev/input/by-path/platform-
thinkpad_acpi-event and toggling the switch twice raises the following
events:
$ sudo input-events 6
/dev/input/event6
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
19:07:04.424098: EV_SW SW_RADIO 0
19:07:04.424098: EV_SYN code=0 value=0
19:07:05.982584: EV_SW SW_RADIO 1
19:07:05.982584: EV_SYN code=0 value=0
I haven't figured out yet, how I can make use of the input event device.
There doesn't seem to be any scriptable daemon listening to it.
Alternativley one can use rfkill uevents via the udev daemon. A working
rule could be:
SUBSYSTEM==rfkill, ATTR{type}==wlan, ENV{RFKILL_STATE}==1,
RUN+=/usr/local/bin/toggle-blue
I guess this bug can be marked as invalid.

I've taken a deeper look into the thinkpad acpi module and found a quite simple solution, which doesnt require deprecated APIs. The patch is tested against upstream kernel 3.15-rc8 as well as Ubuntu-3.13.0-29.53. ** Patch added: 0001-Make-Thinkpad-hw-wireless-switch-propagate-an-acpi-e.patch https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310248/+attachment/4127780/+files/0001-Make-Thinkpad-hw-wireless-switch-propagate-an-acpi-e.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310248 Title: [Lenovo Thinkpad X220] wireless switch doesn't generate an acpi event To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310248/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1310248] Re: [Lenovo Thinkpad X220] wireless switch doesn't generate an acpi event
Hi, unfortunatly the issue has not been fixed in the latest upstream kernel. The kernel version I used to test was: $ uname -r 3.15.0-031500rc8-generic For the test I ran acpi_listen and toggled the switch numerous times. Out of curiosity I also checked some older kernel images: 3.11.10-03111010-generic, which is the last 3.11 iteration, is working fine: $ acpi_listen -t 10 ibm/hotkey HKEY 0080 7000 and its broken with 3.12.0-031200rc1-generic, which is the first 3.12 release candiate. I hope this helps to track it down. ** Tags added: kernel-bug-exists-upstream kernel-bug-exists- upstream-3.12-rc1 kernel-bug-exists-upstream-3.15-rc8 ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310248 Title: [Lenovo Thinkpad X220] wireless switch doesn't generate an acpi event To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310248/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
