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.
