Hello,
I have been experiencing an issue with the Lenovo Carbon X1 Gen 2 -
after resuming from suspend-to-RAM, the adaptive keyboard bar was
completely off and did not respond to any touch.
Thanks to Shuduo San's patches for supporting the Lenovo adaptive
keyboard, I was inspired to device a fix. Seems that simply calling
the ACPI function to set the state of the adaptive keyboard after
resume takes from it off state.
This fix is not perfect because it does not remember the last mode
used. But it makes it useful enough for me (one can't work without
the function keys...). I hope you integrate this anyway into your
proposed changes.
