intel_pstate: This driver implements a scaling driver with an internal governor for Intel Core (Sandy Bridge and newer) processors.
acpi-cpufreq: CPUFreq driver which utilizes the ACPI Processor Performance States. This driver also supports the Intel Enhanced SpeedStep (previously supported by the deprecated speedstep-centrino module).

# see current driver
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver

performance: Run the CPU at the maximum frequency.
powersave: Run the CPU at the minimum frequency.
userspace: Run the CPU at user specified frequencies.
ondemand: Scales the frequency dynamically according to current load. Jumps to the highest frequency and then possibly back off as the idle time increases.
conservative: Scales the frequency dynamically according to current load. Scales the frequency more gradually than ondemand.
schedutil: Scheduler-driven CPU frequency selection.

# current governor
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

# setting to powersave
sudo cpupower frequency-set -g powersave

To change back to the ACPI driver, add the following to the GRUB_CMDLINE_LINUX_DEFAULT variable in the /etc/default/grub file:

intel_pstate=disable

then rebuild the grub config

sudo grub-mkconfig -o /boot/grub/grub.cfg

# ubuntu
sudo apt-get install indicator-cpufreq

# arch
sudo snap install cpufreq
