After updating my ubuntu 13.10 to 14.04 there only these to govenors available for my cpu, instead of additionally ondemand and conservative.
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors performance powersave
My cpu is a Intel(R) Core(TM) i5-4200M CPU @ 2.50GHz, my laptop a LENOVO B5400 80B6QB0 and my kernel version is 3.14.1-031401-generic x86_64
Before updating the four governors were available. If this is important, I have installed tlp and indicator-cpufreq.
How do I get back the missing two govenors? ondemand is really important to me because of power saving.
