Hello calc, thank you for your bug.

A couple of things changed; one was to most 'thinkpad-keys' polling (constantly checking) in most cases and to replace this with ACPI hotkey events.

The second was a last minute change with the kernel to stop the kernel automatically responding to brightness events; this won't work now unless 'gnome-power-manager' is there to deal with it. The longer term solution is a small daemon to sit there and handle the brightness.

Is the A21m one of the laptops that uses Fn-Backspace/Fn-Insert/Fn-Delete for volume, or does it have the separate volume keys.

Secondly, can you post the output of:

  cat /var/lib/acpi-support/*-*

which will help identify for hardware for enable the workarounds. Could you also try running:

  acpi_listen

and pressing the brightness/volume keys, then paste the annotated output here.
