Title:
[Lenovo ThinkPad X1 Carbon 20A8] Wireless switch key doesn't work
Status in “linux” package in Ubuntu:
Triaged
Bug description:
On my X1 Carbon laptop the wireless switch key doesn't work. 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
Pressing the key generates no events (see below) and thus has no effect. So,
it's either my stock kernel doesn't have it, or something else is broken.
Nothing ever fires when I press all extra buttons including the wireless one:
ls /dev/input/by-path/platform-thinkpad_acpi-event -lh

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.
WORKAROUND: Add custom rule to /etc/acpi/events and bound handling to
a different adaptive button that does generate a acpi event.
