That's interesting. I'm on Xubuntu 17.10 with the default Ubuntu kernel, 
and it is currently set to "powersave" without cpufrequtils installed, 
although there is CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y on 
/boot/config-$(uname -r).

So I don't really know what is controlling these settings on my laptop.
