[Bug 22336] Re: laptop overheats when performing CPU intensive tasks.

[Nikolaus Filus]

For using the ondemand scaler you need to load the cpufreq_ondemand
module.

# load module for current session
   sudo modprobe cpufreq_ondemand
# and add it permanently to booting sequence
   sudo echo cpufreq_ondemand >> /etc/modules

BTW: the ondemand scaler gives me around 10°C cooler system (47 against
58 with performance scaler, which seems default for the ubuntu kernel).
The fan is most times off, which also causes a better battery runtime.
