Regardless, I believe your question is: Have you configured `kpowersave's "on battery" to be "dynamic". Answer: yes. I'd like the frequency to ramp-up when there's a need. I want this ramp-up to happen regardless of whether I'm on AC ("Performance") or on Battery ("Powersave"). The ramp-up works when I'm on AC (aka Performance). I have its `Set CPU Frequency Policy' set to `Dynamic' I did the same for Powersave however Powersave doesn't work this way. I've even set the `Default Schemes' for AC _and_ Battery to be `Performance' I hope the above makes sense. Let me know if you'd like .png's of my KPowersave settings.

Just to remove that variable from the equation. What I've noticed is if I wait for 20-40 seconds, `cpufreq-info' reports a policy betweenn 800 MHz and 2.40 GHz. Hmmm. Perhaps the above is what Danny is alluding to? Danny? Holger, here's the output of `scaling_governor scaling_min_freq scaling_max_freq' ondemand 800000 2401000 Please advise and thank you for the help. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Shouldn't the change be instantaneous? It is when I switch to AC before the 17 seconds have elapsed and I'm on Battery.

Kernel issue? Short summary: - latest BIOS - after unpluggin the system from AC source, it takes about 20 to 40 seconds for the ondemand governor to be able to increase frequency If not, I would consider this bug as WONTFIX, or CANTFIX ;) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
