Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.5 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Title:
  Adaptive keyboard breaks with sleep/resume

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have a Lenovo X1 Carbon Gen2. It as the adaptive row of keys that
  change from function keys to volume, etc when you toggle the function
  key. It's always worked fine but with this kernel, after a few
  sleep/resumes, the entire row will go black. If I reboot it will
  return to normal. dmesg throws a bunch of these..

  [30910.489925] thinkpad_acpi: unknown possible thermal alarm or keyboard event received
  [30910.489931] thinkpad_acpi: unhandled HKEY event 0x60c0

  though I'm not sure it's the cause of the failure.
