After KDE update in Saucy, PowerDevil does not suspend the system

[Wladimir Mutel]

Hi,

$ lsb_release -rd
Description: Ubuntu Saucy Salamander (development branch)
Release: 13.10

$ apt-cache policy kde-workspace
kde-workspace:
  Installed: 4:4.10.90-0ubuntu2
  Candidate: 4:4.10.90-0ubuntu2
  Version table:
 *** 4:4.10.90-0ubuntu2 0
        500 http://mirror.yandex.ru/ubuntu/ saucy/universe amd64 Packages
        100 /var/lib/dpkg/status
     4:4.10.4-0ubuntu0.1 0
        500 http://mirror.yandex.ru/ubuntu/ raring-updates/universe amd64 Packages
     4:4.10.2-0ubuntu2 0

Expected behavior : on laptop lid close, the system suspends to RAM. HDD & fan stop, power led starts blinking

Actual behavior : HDD & fan continue running. Power LED glows continuously. Screen is locked with password dialog and display backlight is turned off (it is turned back on shortly after I open the lid).

Same behavior (no suspend) I get when trying to suspend the system through KDE menu ("K" - Leave - Sleep).
"sudo pm-suspend" works as expected (only does not lock the screen).

in .xsession-errors I see these lines added on lid close (looking there remotely by ssh) :

kded(1640) PowerDevil::BundledActions::SuspendSession::triggerImpl: Triggered with "1" false
kded(1640) PowerDevil::BundledActions::SuspendSession::triggerImpl: Triggered with "32" false
kded(1640) PowerDevil::BundledActions::SuspendSession::triggerImpl: Triggered with "1" true
kded(1640) checkSystemdVersion: Unknown version string from Systemd
kded(1640) UPowerSuspendJob::UPowerSuspendJob: Starting UPower suspend job

I remember there were some systemd packages installed during Saucy update. May be I need to install some needed package to make this work ? (which may not currently be listed as a dependency). Now I have installed these power-related packages :

ii acpid 1:2.0.18-1ubuntu1 amd64 Advanced Configuration and Power Interface event daemon
ii libupower-glib1 0.9.20-1ubuntu2 amd64 abstraction for power management - shared library
ii pm-utils 1.4.1-11 all utilities and scripts for power management
ii powermgmt-base 1.31build1 amd64 Common utils and configs for power management
ii upower 0.9.20-1ubuntu2 amd64 abstraction for power management

and these ones for systemd :

ii libpam-systemd:amd64 204-0ubuntu4 amd64 system and service manager - PAM module
ii libsystemd-daemon0:amd64 204-0ubuntu4 amd64 systemd utility library
ii libsystemd-login0:amd64 204-0ubuntu4 amd64 systemd login utility library
ii systemd-services 204-0ubuntu4 amd64 systemd runtime services
ii systemd-shim 3+real-0ubuntu1 amd64 shim for systemd

still no luck after updating most packages from 4.10.90 to 4.10.95

upower has been updated from 0.9.20 to 0.9.21, Kubuntu behavior unchanged.

can this be related to KDE bug https://bugs.kde.org/show_bug.cgi?id=294712 ?

Status changed to 'Confirmed' because the bug affects multiple users.

On my laptop, kde suspend just shuts down wireless connection but does not suspend the system. I tried on different kernels, including versions that worked on raring, but no success.
Also tried:

dbus-send --print-reply --dest='org.freedesktop.PowerManagement' /org/freedesktop/PowerManagement org.freedesktop.PowerManagement.Suspend

and the same thing happens.

pm-suspend works fine.
