Re: Need help adding support for X1 Carbon 2nd Gen's Keyboard

Hello linux-input,

This is my first post on this mailing list (or on any other kernel
list, actually), so sorry if I break unwritten ettiquete. Please let
me know.

So I recently got a X1 Carbon Thinkpad, and so far everything has
been working flawlessly, but the Adaptive Keyboard generates some
ACPI HKEY events with scancodes that are not currently recognised.
They are reported to the kernel successfully so one could set up
shortcuts by using something like `acpid`, but perhaps it would be
better if it generated normal key presses (i.e XF86Something).

I've read through most of the thinkpad_acpi.c code and understand
most of it, but so far I've been unable to report normal keyboard
events from there (and I don't even know if it would be the correct
thing to do.)

I must also say that these keys are somewhat odd. In one of the
modes, there are icons for "snippet tool", "cloud", "man speaking",
"hands in front of camera". I'm not sure what would be the best way
to report these, so I seek your advice here.

At the very least, I can list which scancode is generated by each key.

It would be helpful to know what cations the vendor driver maps for
these keys in Windows (if you still have it available). Then we could
try to come with existing input event definitions for the actions (or
maybe we'd need to add new ones) and map them to the events in
thinkpad_acpi.c.

Thanks.
