hello, after installing the new 4.6 release of KDE on maverick (AMD64, athlon 64 x2 6000+) , kpowersave starts with its dock icon greyed out . the popup label tells that there are no informations available, and the menu is empty. clueless about how to fix that. btw cpu frequncy scaling is working.

Re: kpowersave broken after installing kde 4.6
ok, no clue about why and how but kpowersave is back working. i can set power policies again now and check/change cpu frequency too. note that rebooting twice didn't help before.

Re: kpowersave broken after installing kde 4.6
after another reboot kpowersave is again doing it wrong. increasingly confused

Re: kpowersave broken after installing kde 4.6
kpowersave? on KDE 4.6?
Do you mean the powerdevil plasma widget, which comes as part of KDE 4,6?
see my attached pics on what it looks likeAttached FilesComment

Re: kpowersave broken after installing kde 4.6
I don't know what you mean by 'greyed out', does your taskbar look like my images? That is what kde 4.6 should look like. Perhaps post a screenshot or 2 of what you see with ksnapshot.
I ask this as Kubuntu has not had 'kpowersave' since the KDE3 days, so I want to make sure we are on the same page. I have never seen the battery icon used grayed out, though I have seen the icon not be there when something was missing or not updated in a pre-release version of Kubuntu. The icon is now monochrome color now by default, so it does sort of look gray.
In Kubuntu maverick, powerdevil is installed by default as one of the core applications found in the kdebase-workspace package.
Can you see anything in System Settings's power management area?

Re: kpowersave broken after installing kde 4.6
all right, i have kubuntu 10.10 and kde 4.6.0 and the grey power plug below right of the "info" icon is the kpowersave icon. what puzzles me is why i don't have the "right" plasma applet in place.
the popup says "no info available about the state of battery and AC" . when working it shows up black.

Re: kpowersave broken after installing kde 4.6
I don't recognize that icon, what is it from? The normal applet looks like a battery. I wonder if whatever that icon is for is interfering with something, or simply does not work.
You might want to check that the standard Battery Monitor is enabled and not set to be hidden -right-click on the Arrow at the right-hand side of the System Tray to get to the System Tray Settings
A screenshot of the blank menu might also help.
see my pics for what to look for.Attached FilesComment

Re: kpowersave broken after installing kde 4.6
ok i found that. never opened that menu before :P only, it lacks the core feature i need, CPU frequency scaling. something that allows a two-click setup e.g to set minimum and maximum CPU frequency without having to do it using cpufreq-set from a shell each time. kpowersave could not only set a power saving policy but say, lock max freq to 1 ghz or to the max frequency or set the ondemand policy etc. i noticed that kpowersave is started with the parameter
--force-acpi-check
from the menu, but this prevents it from loading. starting it with no arguments works just half: kpowersave starts but it is completely useless. i amtrying to figure out what is wrong ...Comment

Re: kpowersave broken after installing kde 4.6
again, there is no kpowersave in KDE 4, or in Kubuntu 10.04, which is making this rather confusing....
where did you get it , and how did you install it? Did you upgrade from 8.04 to 10.10? If that is the case, then perhaps it is left-over from the upgrade. It probably will not work with current kernels and acpi implementations.
Unfortunately, powerdevil does not provide this functionality. There are a couple of plasma widgets you can install, though I have not been able to get them to work (I am running Natty currently).
http://opendesktop.org/content/show.php?content=92573
you can download them directly from the "add widgets" you can find when doing this:
http://userbase.kde.org/images.userb...nel-add-45.gif
you will need to install plasma-scriptengines. It does not look like there have been any updates to these widgets in a while, but I don't see why they wouldn't work. If it did then it would be an easy way to do what you want.

Re: kpowersave broken after installing kde 4.6
This functionality was available via dbus calls in KDE 4.5 powerdevil (it was considered a "very advanced" user option since manual cpu scaling often increased power usage rather than reducing it. Kernel handled on-demand cpu scaling is nearly always more effective. (it's easy to imagine that tasks that use cpu, but have limited cpu time available take longer to perform, so manual scaling doesn't really save power).Originally posted by hipsterical
However, there are use cases for manually setting cpu policy (for example, limiting cpu usage to keep a noisy fan down during meetings), and manual cpu scaling was available via dbus in KDE 4.5
Unfortunately powerdevil was rewritten for 4.6 and I haven't found a way to switch cpu scaling policy with dbus in 4.6 powerdevil. The new powerdevil should be more modular, though, so I'm hoping it will get added back eventually (of course it already might have been, and I haven't just found it yet)
EDIT: of course, in KDE 4.6, you can still run scripts with powerdevil on power profile changes, so you could make a script for changing cpu-scaling (via cpufreq-set) when power profile changesComment

Re: kpowersave broken after installing kde 4.6
I'll have to take that back a bit, I looked into it again and realized that had things a bit mixed up in my memory.
In KDE 4.5 you could change cpu governors within powerdevli through solid-powermanagement commands, and switch power profiles with dbus (and haven't been able to do either in 4.6)...I had the things combined in my poor memory.
