Shows that the processor is always working at 2.9 GHz. I see the list of frequencies where I can click on the desirable value but the commandĬat /sys/devices/system/cpu/*/cpufreq/scaling_cur_freq Then I followed the instructions presented in the links belowīut I had no success. I tried to follow the instructions presented inīut it seems that sysv-rc-conf is not available in Ubuntu 18.04. I installed indicator-cpufreq, cpufreqd, cpufrequtils, lm-sensors, psensor, sysfsutils. I installed Ubuntu 18.04 LTS last week and since then I am exhaustively trying to make cpufreq to work.

I usually leaved the processor at this low frequency until I needed more cpu power, when I could choose and change the frequency to a value in a list ranging from 0.80 GHz to 2.9 GHz or 2.9 GHz turbo mode. I was able to configure cpufreq in a way that the Operational System started with the processor working at the minimum frequency.

I like using cpufreq since Ubuntu 14.04, when I bought a Lenovo ThinkPad T440p (Intel Core i7-4600M CPU 2.90 GHz).
