CPU Frequency Throttling

From Linux Mint

Unfortunately, Mint KDE inherits a couple of Kubuntu's CPUFreq quirks. In Mint Main Edition, it was simply a matter of making /usr/bin/cpufreq-selector executable. In KDE, because a different power management daemon is used (and not fully enabled), the correct modules are not even loaded.

However, the fix is pretty easy:

add the following to your /etc/modules.

Code:

your-cpu-chipset

cpufreq_ondemand

cpufreq_userspace

cpufreq_powersave

cpufreq_performance

And replace "your-cpu-chipset" with the powersave module for your CPU (powernow-k8 for me, centrino, acpi, powernow-* etc for others).

Now KPowersave should let you modify powerstates according to the schemes supported by your chipset.
