[opensuse] cannot set cpu frequency in 11.4
I have just switched to 11.4 (kde) and noticed that i cannot set the cpu frequency in powersave mode. Although the power manager profile is set to 'powersave', my cpu frequency spends most of the time at its max value. Any ideas?

That's a feature, it does not make sense to set the frequency manually.

Run powertop so see what is causing this. Sven -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Is has. It helps to keep my laptop at noticeable lower temperature. Any other way to do that?
