Force hibernated system to only wake up on powerbutton press

Hi,

I need the computer to shut down on hibernate (via systemd).

By "shut down" I mean that the computer should not wake up on any other action than Power Button press or a WoL magic packet.

Currently when I hibernate (via systemctl hibernate or clicking on Hibernate in XFCE) the compuer shuts down but powers on on a keyboard press or a mouse click. I don't want that.

I've been ddg'ing around and found /sys/power/disk but "echo shutdown > /sys/power/disk" doesn't seem to have the desired effect. Didn't find anything useful on systemd itself.

When I do a "real" shutdown (i.e. run poweroff or click shutdown in xfce) I get the expected behavior.

Any tips on what I should look into?

thanks,

-miky

Two things to look into: /proc/acpi/wakeup and /sys/devices/.../power/wakeup. You could disable wakeup on devices before hibernating and enable it after thawing (man systemd-sleep).

Also check your BIOS, I know mine has an option to enable/disable resume from keyboard.

AS lucke suggests, check /proc/acpi/wakeup. I.e. on my system there is XHC device with enabled status which is causing wake up from keyboard and mouse.

You can switch state with simple

echo XHC > /proc/acpi/wakeup

If you suspend system and it works, you just need to do this before every sleep. You can use systemd hook (beware that on some systems hooks are in /usr/lib/systemd/system-sleep and on some systems in /lib/systemd/system-sleep. Just check man systemd-suspend.service for correct path):

#!/bin/bash

# /lib/systemd/system-sleep/45fix-usb-wakup
# Disable wakup from USB devices
# 
# This is just modified version of pm-utils script from
# https://gist.github.com/rutsky/1ed8e9779f0b2941c5a6

[[ "$1" = "pre" ]] || exit 0

function print_state {
    cat /proc/acpi/wakeup | grep $1 | cut -f3 | cut -d' ' -f1 | tr -d '*'
}

function disable_wakup {
    dev=$1
    if [ "`print_state $dev`" == "enabled" ]; then
        echo $dev > /proc/acpi/wakeup
    fi
}

function enable_wakup {
    dev=$1
    if [ "`print_state $dev`" == "disabled" ]; then
        echo $dev > /proc/acpi/wakeup
    fi
}

case $2 in
    suspend)
            echo "Fixing acpi settings."

            # Disable wakup by events from USB hubs
            # (e.g. mouse move on some mices)
            disable_wakup XHC
            ;;
