acpi, suspend, hibernate

acpi, suspend, hibernate

[白い熊＠相撲道]

I have GuixSD installed on the Gluglug X200 and would like to issue 
suspend and hibernate commands. Upon inspecting /proc/acpi however it 
seems that this is not built in the current kernel that I have booted.

Do I need to add some acpi, acpi-service etc. to config.scm and 
reconfigure? Could someone specify what exactly is needed?

Many thanks.

I'm not aware of any solution for this. To trigger suspend to RAM
manually on kernel level you need to run:

echo mem > /sys/power/state

We currently lack the pm-utils package, which provides ‘pm-suspend’
(currently I use a script that writes to /sys/power/state as Tomáš
suggested.)  Would you like to give it a try?

We also lack a service to run acpid.  You’re welcome to try it as well
;-).  The main thing is that it requires studying a bit acpid’s options
and possibly provide an API for the /etc/acpi/events rules.

Thanks,

I wonder if it might be better to implement suspend/resume in dmd, so
that services could easily define actions to be run before suspend and
after resume.  I guess the pm-utils approach is to put shell scripts
into /etc/pm.

I second this idea. Dmd is proper place to implement such actions as
services may benefit from performing actions before suspend or after
resume.

Pm-utils package was collection of hacks and workarounds for broken
hardware. It hopefully won't be needed anymore.

To have the list of options richer, there is also UPower
(http://upower.freedesktop.org/) which is designed to take care of
power management.

Best regards,

Good point, and this would be quite easy.

I wonder where things like X session locking should take place though.
(I guess this is one of the things that ConsoleKit and its replacements
took care of.)

Thoughts?

This is an OK solution for suspend. Unfortunately it doesn't allow to hibernate to a swap partition...
