“out of the box” is an expression, it means that it does not require any additional installations or setup for it to do that specific task

simply add cpufrequtils as a startup service. rcconf may come handy to configure this.

cheers

When using KDE you can watch (though not change) the currently selected frequency in “Performence Monitor” aka ksysguard. Ksysguard also comes with “System Guard” applet on kicker panel that can be configured to show the frequency.

what does “box” mean? because you said Fedora 7 should have CPU scaling working out of box.

If you were crunching, you didn’t have to think about such things like clock scaling (except for upward scaling - hehe). I think crunching for a useful purpose makes my PC even more energy efficient than choosing a good PSU ever could. Just think about what we can achieve if every OS was crunching by default

Please, have a look at: http://www.worldcommunitygrid.org/

If you want to choose frequency or governor in gnome applet try run dpkg-reconfigure gnome-applets and set SUID bit.

Hi, for KDE there is very nice application into systray called kpowersave, it comunicates with powersaved daemon and works fine. It can manage also brightness, screensaver, suspend/hibernation, also displays battery status and when running on battery, it shows power consumtion.
