Reset and Power buttons on the system block in Linux

Question

In my Debian Linux PC the buttons Reset and Power on the system block do nothing.

Is it possible the Reset button to make a soft reboot (the same as sudo reboot)? Is it likewise possible the Power button to do soft poweroff (the same as sudo poweroff)?

Weird. I found that Power button works as expected in normal situations. But when XWindows is hanged (the very situation when I need the Power button), the Power button does nothing. I have the pristine Debian /etc/acpid/ and don't understand why is it not working and how to make it works when XWindows is hanged.

Here is my config:

/etc/acpi/powerbtn-acpi-support.sh:

#!/bin/sh

# This script initiates a shutdown when the power putton has been
# pressed. Loosely based on the sample that ships with the acpid package.
# If the acpid sample is present as a real config file (as it was in earlier
# versions of acpid), we skip this script. (Purging and reinstalling acpid
# resolves this situation, or simply deleting /etc/acpi/events/powerbtn.)

if [ -f /etc/acpi/events/powerbtn -o -f /etc/acpi/events/powerbtn.dpkg-bak ] ; then
        logger Acpi-support not handling power button, acpid handler exists at /etc/acpi/events/powerbtn or /etc/acpi/events/powerbtn.dpkg-bak.
        exit 0
fi

[ -e /usr/share/acpi-support/policy-funcs ] || exit 0

. /usr/share/acpi-support/policy-funcs

if { CheckPolicy || HasLogindAndSystemd1Manager; }; then
        exit 0
fi

if [ -x /etc/acpi/powerbtn.sh ] ; then
        # Compatibility with old config script from acpid package
        /etc/acpi/powerbtn.sh
elif [ -x /etc/acpi/powerbtn.sh.dpkg-bak ] ; then
        # Compatibility with old config script from acpid package
        # which is still around because it was changed by the admin
        /etc/acpi/powerbtn.sh.dpkg-bak
else
        # Normal handling.
        /sbin/shutdown -h -P now "Power button pressed"
fi

/etc/acpi/events/powerbtn-acpi-support:

event=button[ /]power
action=/etc/acpi/powerbtn-acpi-support.sh

I have no other files in /etc/acpi/.
