Hi, really nice app. But on my pentium4 i get the message that cpu scalling is not supported --mmaric

Some Feedback and Issues I encountered (GrinGEO)

Some things do not work quite right on my machine; in particular, software events work, but button events are not recognized (lid close, etc.). To someone else above with a lid-close issue you suggested 'please confirm that HAL suspend works". By that, do you just mean "does selecting suspend from the right-click on the guidance-power-management icon work?" If so, the answer is "Yes". If the question is more involved than that, could you provide some more detail about what exactly I need to do to confirm that HAL suspend works? Is there some command to test this? I know nothing about HAL, and looked for documentation, but nothing that would give me any clue as to what to do to confirm that HAL suspend works. Also, I couldn't figure out where the configuration files are for guidance power management. I had posted more details on the Kubuntu forums (which I figured made more sense than posting here), http://kubuntuforums.net/forums/index.php?topic=10464.0, but got no suggestions, whereas there are helpful (and knowledgable - thanks sebas) answers here. Good app, any thoughts on above greatly appreciated. -- bbb

Here's what I get with the above (edited out some 'volume.unmount.valid_options =' entries)

As noted, closing lid, or FN-F3 (suspend) key combination do nothing, but selecting 'Suspend' from log out menu works peachy -- bbb

My issues and remarks (TillBusch)

It would be nice if the UI allowed one to change the cpu frequency, including by profiles. At the moment I've manually inserted the cpufreq modules into /etc/module (cpufreq_conservative, cpufreq_ondemand, cpufreq_powersave, cpufreq_stats, cpufreq_userspace, speedstep-centrino) and I'm using commands like this: "echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor" --tomchance

Big problem with KPM (Karolus (masked.mail_AT_gmail.com))

An Idea:

A little remark:

Suspend/hibernate/shutdown when the system is more than n minutes: This option doesn't seem to work for me. I'm running Kubuntu feisty with all the latest updates. The screen only blanks after some time, but doesn't hibernate or suspend. If I manually hibernate (from the rightclick dialog) everything works fine. Do I have to enable something to get this working? Could this be a bug? Please email me if you need more information (stivani_at_gmail.com) --stivani

Hi, I like the app, but I have a few things that I think could be improved. Generally, it's good to have stuff configured with some sensible default values (one of the points I appreciate most about (k)ubuntu). But it would also be good to have a way to set one's own configs, and some documentation what the program exactly does and how to influence this. Examples:

Please, please give some documentation. I would love to troubleshoot this kind of stuff, but at the moment this is more of a riddle than productive problem-solving. Let's not lose the good Linux way of having documented workings and interfaces and not just a GUI. -- Ysanne

Workarounds

Suspend/Hibernate/Battery laptop button support

You can add support for laptop keys with the following script: 

PM=`dcopfind -a 'power-manager-*'`
if [ $? != 0 ]
then
    exit 1
fi

case $0 in
  *suspend*)
      dcop $PM power-manager suspend
      ;;
  *hibernate*)
      dcop $PM power-manager hibernate
      ;;
  *)
      dcop $PM power-manager showTip
      ;;
esac

Save this script to some directory (for example ~/bin) and give it some name (pm-hotkey), then create symbolic links for three actions: 

ln -s ~/bin/pm-hotkey ~/bin/pm-suspend
ln -s ~/bin/pm-hotkey ~/bin/pm-hibernate

Now you can assign the keys with KHotkeys (System Settings -> Accessibility -> Input Actions):

  1. Select Add New Action

  2. Give it a name (like "Suspend", "Hibernate", "Battery")

  3. Set Action type to "Keyboard Shortcut -> Command/URL (simple)"

  4. Click on Keyboard Shortcut tab

  5. Click on None button, press the key you want to assign action to (it will return one of the following: XF86LaunchB, XF86Standby, XF86Sleep)

  6. Click on Command/URL Settings

  7. Browse ans select one of the scripts (~/bin/pm-hotkey, ~/bin/pm-suspend, ~/bin/pm-hibernate)
