Quote: |
Power Management configuration module could not be loaded.
The Power Management Service appears not to be running.
This can be solved by starting or scheduling it inside "Startup and Shutdown"

When I restart the power management server i get a brief message about no suitable back end plugins or something like that. what did i miss?

A couple of wild guesses:
- Do you have acpid running in your default runlevel?
- Do you have sys-power/pmtools installed?
If the answer is yes to both, sorry, not sure where you go next. _________________ Greybeard |

Thanks! I had to install pmtools and add acpid to default, but still no luck.

I had the same problem and starting udev and adding it to the default runlevel solved it for me. |

I was able to resolve this by installing upower which does not appear to be a dependancy. Note the upower in the following:
laptop ~ # solid-hardware query 'IS Battery'
virtual QStringList Solid::Backends::UPower::UPowerManager::allDevices() error: "org.freedesktop.DBus.Error.ServiceUnknown"
laptop ~ # |

Well I finally solved this. I noticed that upower was not listed as part of the `ps -e` process list so I tired to run it manually to see what would happen. basically it came up with the error "(upower:6205): libupower-glib-WARNING **: Couldn't connect to system bus: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory". This is caused by udev not running at startup. A quick rc-update and everything works.
I think this thread as sucessfully covered every possible problem with PowerDevil starting. Thanks |

Hello!
I bumped into this problem too.
Unfortunately I cannot see the battery icon working anymore since one of the recent updates.
I have gentoo-sources-3.12.6 and kde-4.11.2-r1.
upower doesn't seems to have an init.d script and it is not running. What is strange is that I didn't modify anything so far.
This is what happens to me.
I receive the following error at the top of my screen after login:
KDE Power Management System:
Code: | KDE Power Management System could not be initialized. The backend reported the following error: No valid Power Management backend plugins are available. A new installation might solve this problem. Please check your system configuration |
And then, if I go to System Settings->Power Management, the pane on the right is greyed out and there is a message:
Code: | Power Management configuration module could not be loaded. The Power Management Service appears not to be running. This can be solved by starting or scheduling it inside "Startup and Shutdown" |
But the Power management is shown as running in the Service Manager section.
One more thing:
the device notifier is no longer working also. Indeed, every time I plug an USB drive, nothing happens anymore. There's also another problem: the brightness control is broken as well.
Could you help me please?

OK,
I've also tried to add udev in the default runlevel, install pmtools but the problem is still there.
UPower was already installed. ACPID is already in the default runlevel.
But I guess the problem is this:
Code: | upower -d
(upower:5408): libupower-glib-WARNING **: Couldn't enumerate devices: Failed to execute program /usr/libexec/dbus-daemon-launch-helper: Success
(upower:5408): UPower-WARNING **: failed to enumerate: Failed to execute program /usr/libexec/dbus-daemon-launch-helper: Success |
So I've found the following solution here:
Code: | emerge --noconfmem dbus dbus-glib polkit consolekit pambase sudo |
