Two things to do.. 1. First you need to make your own settings file: kernel-config save my-settings It will tell you the place where it got saved. 2. Then open it with leafpad (might need to install leafpad): leafpad /home/user/.kernel/my-settings (And edit threshold and sampling) 3. And secondly write as root in terminal. echo 125000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/avoid_frequencies (please use tab-key to finish a dir.. /sys/devi "tab")
