kacpimon then reports on what it sees while it is connected.
Use kacpimon to make sure your kernel is sending acpi-related events via the three sources mentioned above.
Since both acpid(8) and kacpimon connect to the same sources, be sure to stop acpid(8) before running kacpimon. If you are using upstart(7), use initctl(8) to stop acpid(8). If you are using systemd(1), use systemctl(1) to stop acpid(8). If you aren't using either of those, you can try killall(1) to stop acpid(8).
Be sure to run kacpimon as root or else it won't be able to open /proc/acpi/event or the input layer:
