       kacpimon - Kernel ACPI Event Monitor




       kacpimon is a monitor program that connects to three sources of ACPI events:

              1. /proc/acpi/event
              2. netlink
              3. the input layer (/dev/input/event*)

       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:

              sudo kacpimon

       If you want to pipe the output of kacpimon to a file, be sure to use the "Esc" key to exit
       rather than Ctrl-C.  Using Ctrl-C will cause output to be lost.

       - Make kacpimon something that actually gets installed?
