CPU sitting at lowest clock speed when pstates is disbled
So in order to have more control over cpu with cpufreq I need to disable pstates so it uses acpi. Now when I add "intel_pstate=disable" to grub and reboot it boot but stay on ~700MHz frequency when I try to change it via cpufreq gui of via terminal but it doesn't change. When pstates is not diabled I can use cpufreq but only to set to performance or ondemand with it disabled it offers more options but doesn't work. Note in install document it says I should disable pstates.
Here is screenshot with pstates disabled.
enter image description here
My CPU is i5 2520m if that matters.

Your processor seems to be running at below its normal minimum, which means that Clock Modulation might be involved. It is a Dell LapTop and is it using a Dell AC adapter? The intel_pstate CPU frequency scaling driver does not have the ondemand governor. What install document said to disable the intel_pstate driver? My input is to ignore those instructions and use it with the powersave governor. For the acpi-cpufreq driver you are using the userspace governor, which seems to be clamped at the minimum for the processor, so at least use another governor if you insist on using that driver.
