Created page with "= Debian Stretch = * From https://wiki.debian.org/Suspend <pre> Debian Jessie ... With systemd, pm-utils and its hooks are not used any more, instead there's systemd-suspend..."

New page

Debian Jessie

With systemd, pm-utils and its hooks are not used any more, instead there's systemd-suspend.

== Power button management ===

Part of the official Debian documentation is outdated, still using acpi config folder:

* https://wiki.debian.org/ConfigurePowerButton

We can cosider the follows

* https://wiki.debian.org/Suspend
* https://wiki.debian.org/SystemdSuspendSedation
* https://wiki.archlinux.org/index.php/Power_management#ACPI_events

And edit the config file /etc/systemd/logind.conf to handle the behavior that we want

For instance, to put the PC to sleep on power button press, change the value of HandlePowerKey property unde the [Login] section from the default
<pre>
#HandlePowerKey=poweroff
</pre>
to
<pre>
HandlePowerKey=suspend
</pre>

* Note, pm-util is not necessary anymore and apparently can be removed:

<pre>apt-get remove --purge pm-utils</pre>

* There is a package called upower that is used to abstract the power management layer, but in my dell notebook XX there is something that cause an eternal sleep request loop, and it is using upower, so I removed this package and the issue disappeared (but I can still use power manager button, lid close event still sleep, all work as expected apparently):

<pre>apt-get remove --purge upower libupower-glib3</pre>

= Before Debian Stretch =

(or before jessie, whenever /etc/acpi folder was used)

* Edit file 'acpi/powerbtn-acpi-support.sh'

* replace the 'shutdown' command with the 'pm-suspend' one
for example:

<pre>
### /sbin/shutdown -h -P now "Power button pressed"
pm-suspend
</pre>
