[SOLVED] Dbus-send, UPower, HybridSleep and Slackware-current

Tonus · 06-24-2019, 04:09 PM

Hi all,

When I switched to i3wm I looked for a non root way to suspend / hibernate.
I found this :

Code:

dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend

Or

Code:

dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Hibernate

Everything works well and I am happy with it... But :

I can't find a way to have HybridSleep working the same way (did not find something in UPower or dbus docs, pm-suspend-hybrid works)

Does someone has some clue?

AFAIK, all power operations require root. If you're able to do it as user, it's because some command has the appropriate permissions (4755).

Try running this and see if UPower has an appropriate method for it:

qdbus --system org.freedesktop.UPower /org/freedesktop/UPower|grep method

On my machine there isn't a HybridSleep method to call, but I don't know whether that is just because of my hardware so you'd best check yours as well.

If all else fails, you can always ignore all this dbus crap and just create a sudo rule and optionally a wrapper script to call pm-suspend-hybrid directly.

I would recommend using ConsoleKit instead. The UPower we have in Slackware is quite old, and the new version is not going to have shutdown/restart/hybernate/suspend at all, so better to migrate now.

Shut down:

Code:

dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Stop

Restart:

Code:

dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Restart

Suspend:

Code:

dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Suspend  boolean:true

Hibernate (suspend to disk):

Code:

dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Hibernate  boolean:true

Hybrid Sleep (suspend + hibernate):

Code:

dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.HybridSleep  boolean:true

Edit: I just tried it and it works, but I needed to be root. I assume that is because of this (from the link above):

Quote:

This method assumes that you are given permission to shut the system down via PolicyKit. The default group for this is wheel. To change this, edit /etc/polkit-1/localauthority.conf.d/50-localauthority.conf as root.

Thank you all three for your answers!

I'll definitely will update my key bindings and scripts according to the informations you provided.

No hybrid-sleep there neither, now I know, thank you ! (I was looking for such information)

Great thanks for listing all these commands. It works as previously (even might be faster). As it is for my laptop, mostly one user member of the wheel group, I had no need to edit /etc/polkit-1/localauthority.conf.d/50-localauthority.conf as root.
