Can you check the SuspendAllowed and CanSuspend properties of org.freedesktop.UPower? Both of them have to be true in order for it to announce suspend support.

Hi Kai

First: my apologies for stating "shutdown and hibernate" when I meant to say "suspend and hibernate" of course.

Here are the results on my laptop:

$ qdbus --system org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.CanSuspend
true
$ qdbus --system org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.SuspendAllowed
true

And this actually suspended the laptop:
$ dbus-send --system --print-reply  --dest='org.freedesktop.UPower' /org/freedesktop/UPower org.freedesktop.UPower.Suspend
method return sender=:1.14 -> dest=:1.52 reply_serial=2

Still, no suspend option in the Leave menu or in the System Settings > Power Management.

Are you really sure there's no login1 service on DBUS? It may not be visible but it's activated on first usage.

The code responsible for querying the suspend/hibernate capabilities first tries with login1 and only if that's not available, falls back to upower. It not only checks whether the method is available (CanSuspend) but also whether it's allowed by polkit (SuspendAllowed), see below for the snippet:

   if (m_login1Interface) {
        QDBusPendingReply<QString> canSuspend = m_login1Interface.data()->asyncCall("CanSuspend");
        canSuspend.waitForFinished();
        if (canSuspend.isValid() && (canSuspend.value() == "yes" || canSuspend.value() == "challenge"))
            supported |= ToRam;

        QDBusPendingReply<QString> canHibernate = m_login1Interface.data()->asyncCall("CanHibernate");
        canHibernate.waitForFinished();
        if (canHibernate.isValid() && (canHibernate.value() == "yes" || canHibernate.value() == "challenge"))
            supported |= ToDisk;

        QDBusPendingReply<QString> canHybridSleep = m_login1Interface.data()->asyncCall("CanHybridSleep");
        canHybridSleep.waitForFinished();
        if (canHybridSleep.isValid() && (canHybridSleep.value() == "yes" || canHybridSleep.value() == "challenge"))
            supported |= HybridSuspend;
    } else {
        if (m_upowerInterface->canSuspend() && m_upowerInterface->SuspendAllowed()) {
            qCDebug(POWERDEVIL) << "Can suspend";
            supported |= ToRam;
        }

        if (m_upowerInterface->canHibernate() && m_upowerInterface->HibernateAllowed()) {
            qCDebug(POWERDEVIL) << "Can hibernate";
            supported |= ToDisk;
        }
    }

Hi Lukáš,

I am certain that there is no Login1 service available on DBUS. For the moment, Slackware is not prepared to add anything looking like systemd or logind to the distro. We still use ConsoleKit 0.4.5 for session management and may switch to ConsoleKit2 in future.

This is interesting. When opening the systemsettings > powermanagement, and while monitoring DBus calls with dbus-monitor I expected so find calls to org.freedesktop.UPower but instead I see calls to org.freedesktop.PowerManagement and those return false:

method call sender=:1.59 -> dest=org.freedesktop.PowerManagement serial=37 path=/org/freedesktop/PowerManagement; interface=org.freedesktop.PowerManagement; member=CanSuspend
method return sender=:1.4 -> dest=:1.59 reply_serial=37
boolean false
method call sender=:1.59 -> dest=org.freedesktop.PowerManagement serial=38 path=/org/freedesktop/PowerManagement; interface=org.freedesktop.PowerManagement; member=CanHibernate
method return sender=:1.4 -> dest=:1.59 reply_serial=38
boolean false

Applications are not supposed to call UPower directly. The FDO interface is standardized and, in our case, provided by PowerDevil.

Hi Kai, I understand. But I was trying to indicate the difference (true versus false) of what UPower thinks about ability to suspend and what PowerDevil makes of it.

Is it perhaps caused by solid's configuration? When compiling solid-5.7.0 I noticed:

-- The following features have been disabled:
 * Solid::PowerManagement , WIP: Freedesktop backend for the asyncrhonous api
 * Solid::PowerManagement , WIP: Freedesktop backend for the asyncrhonous api

And I thought, if that gets disabled by default and it is a WIP, it surely is not required for proper working of powerdevil, correct?
Because I also get:
$ qdbus org.kde.Solid.PowerManagement /org/freedesktop/PowerManagement CanSuspend
false

Note that I claim no knowledge of the topic whatsoever, I just try to be as verbose as possible.

This must be related to policies somewhere, because when root starts a Plasma 5 session, the Suspend and Hibernate options are present.
What I fail to understand is why this was never an issue in KDE 4 sessions, nor in XFCE. It started happening with Plasma 5. So is PowerDevil evaluating policies differently than before?

Do you have polkit-kde-authentication-agent-1 running? That would grant you the privs

.xsessions-errors: powedevil starts before polkit-kde-authentication-agent-1

Hi Lukas,

I'm trying to help Eric sort out this issue on our Slackware systems.
polkit-kde-authentication-agent-1 is indeed running, but according to my .xsession-errors (attached) it is started by klauncher *after* powerdevil is started by kded. Is this expectect behavior? Otherwise is there a way to change start-up order or inhibit kded to start the services until after klauncher is done?

Hmm, that could indeed be the problem. polkit-kde-authentication-agent-1 is started by the session which is always after kded modules (powerdevil being one)... 

I wonder what happens when you restart kded (and hence powerdevil's kded module) after the session has been up and running (just killall -9 kded5 && kded5) and then restart plasmashell (kquitapp5 plasmashell && plasmashell)

Thank you for your quick reply. 
I issued the commands you suggested and that did the trick (partially). Suspend & Hibernate show up in the Leave Menu, Shutdown & Reboot are still missing. 
Now, when powerdevil starts it CAN contact ConsoleKit, whereas in the 'normal' start-up sequence there's an error message about not contacting CK.
Can the start-up sequence be changed from startkde?

Hi,

Are there any updates on this bug? Is more information necessary?
Thank you.

On my laptop, suspend and hibernate will indeed appear after killing kded5 and restarting plasmashell.

You will get shutdown & reboot back by editing /usr/bin/startkde and changing the line:
    kwrapper5 ksmserver $KDEWM $KSMSERVEROPTIONS
to
    ksmserver $KDEWM $KSMSERVEROPTIONS
i.e. by removing the "kwrapper5". Making this edit by itself will not change anything with regard to suspend/hibernate, they are two separate issues.

I can confirm that removing kwrapper causes shutdown/reboot entries to reappear. It turns out that launching ksmserver with kwrapper5 causes org.freedesktop.ConsoleKit.Manager.CanStop to return false. Not really sure what the cause of that could be.

I have a theory. 
Console Kit sets a an environment variable which possibly isn't being transferred.

Can you cat /proc/PIDofKSMServer/environment 

both with and without kwrapper5 and attach results

Note that the environment with kwrapper is from "kwrapper5 ksmserver" and "ksmserver [kdeinit5]" has none.

Hi Eric,

the part with the missing restart/shutdown in the menu, can be also solved by providing polkit rules for ck restart/shutdown.

Polkit rules for upower make also suspend/hibernate appear in menu.
But, I do get on gentoo the very same errors logged regarding powerdevil not registering a ck session, thus no suspend.

Polkit configuration file for suspend/hibernate

If this file is added to /etc/polkit-1/localauthority/50-local.d/ (for instance as "30-org.freedesktop.upower.pkla") it will enable the missing Suspend and Hibernate options in the Plasma 5 desktop.

I have attached a polkit file which enables the missing suspend/hibernate features in my Plasma 5 desktop.
Thanks to luis' comment in this blog article: http://alien.slackbook.org/blog/kde-5_15-02-release-for-slackware-current/
I want to suggest that this bug report can be closed now that there is a working solution.

In that same article, two other polkit files are proposed to enable the missing shutdown/rebootfeatures without the need for removing the kwrapper5 command from the KDE startup script "/usr/bin/startkde".
For your reference, this is the content of those two files.
Note that i have altered them slightly compared to the proposals in my blog, because I want to limit this functionality to users in the "power" group:

cat /etc/polkit-1/localauthority/50-local.d/40-org.freedesktop.consolekit.system.stop-multiple-users.pkla

Thanks for your feedback and support!

*** Bug 351447 has been marked as a duplicate of this bug. ***

For Gentoo, just adding the Polkit files will not suffice. Only after respawning first kded5 and then plasmashell am I able to see Sleep and Hibernate buttons at all. And even then the Sleep button does not work, but only locks the screen after showing a black screen for a few seconds.

I had the same problem as Manuel on my gentoo box. Even after adding the Polkit files nothing changed, both shutdown/reboot and sleep/hibernate options were not shown.
In my case the reason was that my user was not a member of the group "users". When I added my user account to this group, everything was OK.

It is part of the upgrade guide: https://wiki.gentoo.org/wiki/KDE/Plasma_5_upgrade#Missing_shutdown.2C_reboot.2C_suspend_and_hibernate_buttons_when_using_OpenRC

I still have this problem. I'm running gentoo with openrc (no systemd), all software in current versions to this time, however there is some progress since recent time when parts of kde5 was upgraded that I see restart and shutdown options. I've tried everything from this thread except restarting kded5 and powerdevil from running session, removing kwrapper from startkde doesn't help, I was always member of group "users", polkit rules are in place, all dbus commands have same output as in this thread and I have a right to suspend as a user. However my system don't support hibernate, I hope this is not a problem. Maybe the problem is that powerdevil can't contact consolekit daemon.

 .xsession-errors
powerdevil: Can't contact systemd
powerdevil: Can't contact ck

Check whether the dbus service org.freedesktop.ConsoleKit is running and it has permission to access it. That message is from the inhibition manager and unrelated to suspend, though.

I believe so, it returns this:

qdbus --system org.freedesktop.ConsoleKit
/
/org
/org/freedesktop
/org/freedesktop/ConsoleKit
/org/freedesktop/ConsoleKit/Manager
/org/freedesktop/ConsoleKit/Seat1
/org/freedesktop/ConsoleKit/Session2

I've tried with fresh new user and it is still the same. Only difference is that new user when click restart (restart computer) only X session is actually restarted, this user is only member of "users" group, while my actual user is member of more groups. I see that slackware and gentoo are using different groups power and users, and that user above who has reported same symptoms resolved it by adding user to group "users". Maybe I have some group rights wrong somewhere in filesystem, process, socket, anything, or is is solely a way for authorization by those polkit rules? Is there any way to debug why powerdevil can't contact consolekit?

Please check your consolekit setup w/ '$ ck-list-sessions' from inside your plasma session.

Make sure your system-login file is valid:
https://wiki.gentoo.org/wiki/KDE/Plasma_5_upgrade#Missing_shutdown.2C_reboot.2C_suspend_and_hibernate_buttons_when_using_OpenRC

I believe I have everything right regarding https://wiki.gentoo.org/wiki/KDE/Plasma_5_upgrade#Missing_shutdown.2C_reboot.2C_suspend_and_hibernate_buttons_when_using_OpenRC

Had same problem with suspend in Gentoo with plasma 5.5.5. Localauthority files mentioned above didn't help. Managed to solve missing suspend issue by adding polkit rule instead:

polkit.addRule(function(action, subject) {
    if (action.id == "org.freedesktop.upower.suspend")
    {
        return polkit.Result.YES;
    }
});

Hi, I'm happy to report that the problem seems to be finally fixed with plasma 5.8 (just confirmed by my experience, not changelog).
