Yeah. Power management is, once again(!), undergoing DBus API changes.

We'll need to look at org.freedesktop.DeviceKit.Power in addition to the
existing interface.

Hopefully that one won't change!

I recently pushed a fix that allows the plugin to work on the older systems (Jaunty etc) that use PowerManagement and newer ones (Karmic) that use DeviceKit Power.

I accidentally clicked on the status... :s Sorry..

This bug was fixed in the package gnome-do-plugins - 0.8.2.1+dfsg-1~ubuntu1

---------------
gnome-do-plugins (0.8.2.1+dfsg-1~ubuntu1) karmic; urgency=low

  * Upload from pkg-cli-apps SVN to get this new bugfix release into Karmic.

Latest Karmic, trying to hibernate:

First, I assume youre using the new 0.8.2.1 which fixes this for Karmic.

Second, what you see there is a known NDesk DBus bug. Their bug report even has a patch that fixes it attached to it, but afaik it was never put into their trunk and thus not fixed. I personally downloaded their source, applied the patch, and voila it works fine!

Hi Robert,

Could you file a bug at Debian about this ndesk-dbus issue and attach the patch and we'll see if we can get it applied there. Maybe we'll even be able to SRU into Karmic in a couple of weeks. If you could poke upstream about getting it applied too then it would help us to know that the patch is safe.

Regards,
Iain

Bug #377672 seems to be the NDesk issue and yes, I'm running with the updated GNOME Do with all Karmic updates applied.

This is broken now again in Maverick ?

I have the same problem in Lucid. Although I don't get the error messages.

dbus-monitor outputs this for hibernate:

method call sender=:1.27 -> dest=org.freedesktop.DBus serial=13 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameHasOwner
   string "org.freedesktop.PowerManagement"

And this for suspend:

method call sender=:1.27 -> dest=org.freedesktop.DBus serial=14 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameHasOwner
   string "org.freedesktop.PowerManagement"

Broken in Maverick.

The packaged version of do-plugins most likely does not contain the UPower code that is in trunk. Try compiling from source.
