I upgraded to day to KDE 4.11.1 from KDE 4.11.0. Also, Kernel 3.11 was installed.
After the upgrade, I receive the following error at the top of my screen after login:
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.
So I went to System Settings>>Power Management and the pane on the right is greyed out and there is a message:
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"
Added:
So I go to System Settings>>Startup and Shutdown>>Service Manager and it states that the service is running. SO I stop and start the service and I receive the original message.
I also booted in the 3.10.25 kernel and the problem persists. I created a new user and logged into KDE and the problem persists. I ran ps -ef | grep upower and here is the output:
I ran /user/lib/upower/upowerd since it is runable by a normal user. I received the followingoutput:
(upowerd:3843): UPower-WARNING **: Failed to acquire org.freedesktop.UPower: Connection ":1.122" is not allowed to own the service "org.freedesktop.UPower" due to security policies in the configuration file
(upowerd:3843): UPower-WARNING **: Could not acquire name; bailing out
I am using openSUSE 12.3 Tumbleweed. Also, I loaded the previous kernel, and the problem persists. SO the only variable is KDE or the various multimedia updates which were also updated.
Thank you for that. By coincidence a few hours ago I upgraded my 12.3 partition to Tumbleweed using zypper dup. On first reboot I received the same error as above, and running KDE 4.11 from Tumbleweed repo. My standard 12.3 was a fairly recent clean default install, fully updated prior to the upgrade, and no Packman repo added or packages ever installed.
In fact on Tumbleweed I only booted so far with the 12.3 updated kernel-desktop-3.7.10-1.16.1.x86_64, so it’s probably not down to the latest Tw kernel.
The errors as shown above are the same here, and starting and stopping the service in System Settings appears to do nothing for the problem.
Good news, so the broken packaging is rebuilding on the build service. We may not see it in the repo until after the planned maintenance outage overnight tonight (GMT/UTC) i.e. sometime tomorrow all being well.
Even better news, I was wrong! The 4.11 KDE package updates to fix this are now available in Tumbleweed repo. Just installed them. The power management service issue appears to now be fixed.
