http://forums.fedoraforum.org – I've recently upgraded to fedora 18, from 17, and with 17 I was able set my cpu frequency scaling governors with a simple script. I recently tried to run the script to set my cpu to ondemand and I've discovered that the folders and scaling_governor files are no longer. The path to these had been : /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor. When I run cpupower frequency-info I get: Quote: analyzing CPU 0: no or unknown cpufreq driver is active on this CPU boost state support: Supported: no Active: no Any idea (HowTos)
