       sleepd - puts a laptop to sleep during inactivity or on low battery


       sleepd  [-s command] [-d command] [-u n] [-U n] [-I] [-i n] [-E] [-e filename] [-a] [-l n]
       [-w] [-n] [-v] [-c n] [-b n] [-A] [-H] [-N [device] [-r n] [-t n]]


       sleepd is a daemon to force laptops to go to sleep after some period of  inactivity.  This
       is useful if your laptop does not automatically go to sleep when you aren't using it, and,
       like me, you often forget to shut it off. It is also capable of suspending a  laptop  when
       its battery gets very low.

       sleepd  can detect activity in several ways. The default is to poll both event devices and
       interrupts to detect when your laptop is in use due to keyboard  or  mouse  activity.   It
       defaults  to  polling  /dev/input/event*.  You  may specify a list of device files to poll
       instead, or use options to enable other means of checking for activity (network  activity,
       utmp,  or load average). After a configurable amount of time with no activity, sleepd runs
       a program to put the laptop to sleep.


       -h, --help
              Show summary of options.

       -n, --nodaemon
              Don't fork to background; run in forground.

       -v, --verbose
              Output status messages.

       -u, --unused
              Number of seconds the laptop can remain idle before being put to  sleep.   Defaults
              to 600 seconds (10 minutes). Set to 0 to disable any sleeping due to idleness.

       -U, --ac-unused
              If  set, controls the number of seconds the laptop can remain idle before being put
              to sleep when running on AC power. If not set, the laptop will not sleep when  it's
              on AC power.

       -e, --event
              Adds  an event file to the list that is watched. Using this switch disables polling
              all files in /dev/input/event*.

       -E, --no-events
              This switch disables event device polling.

       -l, --load
              If set, a load average higher than this  number  will  prevent  the  computer  from
              sleeping If not set, the computer will ignore the load average.

       -w     If set, sleepd will also check idletime based on utmp. This will prevent the system
              from sleeping while remote connections are active. It uses the time limit from -u.

       -i, --irq
              Adds an irq to the list that is  watched.  Using  this  switch  disables  automatic
              detection of keyboard and mouse irqs unless -a is specified as well.

       -I, --no-irq
              This switch disables interrupt polling.

       -a, --auto
              Automatically detect and watch mouse and keyboard irqs.

       -s, --sleep-command
              Command  to  run  to put the laptop to sleep. Defaults to "apm -s" for systems with
              APM and "pm-suspend" for systems with ACPI.

       -b, --battery
              If this option is specified, the daemon  will  put  the  laptop  to  sleep  if  the
              percentage of battery charge drops below the specified number and the system is off
              AC power. This is useful for some laptops which don't handle  this  themselves.  It
              supports using APM, ACPI, and HAL for querying battery status.

       -d, --hibernate-command
              A command to run instead of the regular sleep command when the battery is low. This
              can be useful if you want to make the system go to sleep when it's not active,  but
              suspend to disk if the battery is low. If not set, the sleep command is used.

       -N, --netdev
              Monitor  a  network  interface  for  activity  based  on  packet count. eth0 is the
              default. This option may be used more than once with different network interfaces.

       -t, --tx-min
              Set a baseline transmit raffic rate in packets per second for  network  monitoring.
              Requires -N.

       -r, --rx-min
              Set  a  baseline receive traffic rate in packets per second for network monitoring.
              Requires -N.

       -A, --and
              Only go to sleep if all specified conditions are met. For example,  only  sleep  if
              idle and if the battery is low.

       -c, --check-period
              Number  of  seconds  between  check on system status. Defaults to 10 seconds, which
              should be fine generally.

       -H, --force-hal
              Force HAL to be used instead of ACPI or other methods to query battery status.




       Interrupt monitoring cannot always detect keyboard and mouse.  If the  keyboard  or  mouse
       interrupt  is  shared (as is common with usb devices), other devices on the same interrupt
       can keep the system awake.  Use event device polling instead.
