I scale down the CPU frequency by indicator-cpufreq on Ubuntu 12.04.After I suspend Ubuntu and wake it up, the CPU goes back toon demand (the default). I wonder if there is a way to keep the CPU frequency after scaling it?NOTE: sometimes, my Ubuntu can't wake up completely, and my laptop can easily become overheated under CPU frequency on demand.
