ACPILID(4)              NetBSD Kernel Interfaces Manual             ACPILID(4)


NAME

     acpilid -- ACPI Lid Switch


SYNOPSIS

     acpilid* at acpi?


DESCRIPTION

     The acpilid driver supports ACPI ``lid switches''.  The powerd(8) daemon
     can be used to control actions against the events of opening or closing
     the lid.  The script used is /etc/powerd/scripts/lid_switch, and the
     events are either pressed (the lid was closed) or released (the lid was
     opened).


EXAMPLES

     The following example modifies the mentioned script in order to put the
     system into (S3) sleep when the lid is closed:

           ...

           case "${2}" in
           pressed)
                   logger -p info "${0}: suspending..."

                   # As in sleep_button, kill some daemons.
                   #
                   /etc/rc.d/dhcpcd stop
                   /etc/rc.d/network stop
                   /etc/rc.d/wpa_supplicant stop

                   # Suspend.
                   #
                   if /sbin/sysctl hw.acpi.sleep.state >/dev/null 2>&1; then
                           /sbin/sysctl -w hw.acpi.sleep.state=3
                   fi

                   # Waking up.
                   #
                   /etc/rc.d/wpa_supplicant start
                   /etc/rc.d/network start
                   /etc/rc.d/dhcpcd start

           ...
