    Power manager on tray

    Hello,
    I have two PCs both running an up-to-date 8.04. One is a laptop and one is a desktop.
    On the laptop I got, by default, a nice power manager applet on the tray; if I hover the mouse over it, it tells me the current CPU frequency; if I right-click on it, I can choose the CPU frequency policy (Dynamic, Performance, Powersave). It works great and I really use it depending on my needs (performance or battery time...)

    I would like to have the same thing on my desktop PC. My CPU can scale the frequency of its cores. But I had to install cpufrequtils and cpusysutils, and I didn't get the tray icon, and had to manually set the cpu freq policy; and even then, I cannot choose "performance" so that the CPUs are running at full speed, ready to give the needed power. I would sometimes need this setting because the "ondemand" is a bit conservative - many tasks aren't "power-hungry" enough to switch the cpu to its max frequency, and thus those tasks are executed sluggishly.
    For example, if I have to browse some photos, the thumbnail creation doesn't trigger the full speed on the CPU, and is much slower than I would like. The only way to have full-speed would be to disable frequency scaling via konsole, and reboot. Not an option.
    So.. how can I set up my desktop so that it behaves like the laptop?

    Thanks

    The package you want is Kpowersave. On the desktop you have to run it (Alt-F2 "kpowersave") and then it will put the icon on your taskbar. Once it is running, you can use it the same way that you use it on the laptop.

      Hi dibl,
      Thanks for the reply. But kpowersave is not the same program I have on the laptop. Both the appearance and use are different.
      And the main problem is that when I run kpowersave on the desktop, there's no quick way to set the CPU policy: I have to enter the kpowersave configuration screen; and from there, it says that the "CPU frequency policy is not supported" - but I know it is, because I can set it with the Console.

      The program on my laptop, I don't know its exact name - there's no "about" menu entry anywhere - but its main window is titled "Power Manager"; but I couldn't find any package named like that.
