[RESOLVED] Changing CPU frequencies by GUI on Ryzen

RESOLVED

DO NOT disable “Cool n Quiet”

I have a Ryzen 5900X, and I was able to change the frequency by using cpufreqd/cpufrequtils & the CPU Frequency indicator (indicator-cpufreq on Ubuntu)

Now, for some reason, it’s not working. The indicator is not launching

$ sudo cpufreq-set -g ondemand
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
   for example because of hardware which cannot be set to a specific frequency
   or because the userspace governor isn't loaded?

I also tried CoreCtrl, but nothing shows

Is there an alternative?

By chance did you update the kernel or application but not both?

What happens when you try to start cpufreqd? From the looks of it, it seems that is not running. Finding the reason for that may make the other thing fall in place.

It’s fixed now. I ran update-initramfs, and that seemed to have solved it next boot.

That is not running automagically after installing or upgrading the kernel? I am surprise your kernel can even boot.

Actually, I spoke too soon. I don’t know how it worked before, but it stopped working again.

EDIT: solved (see top of the post)

Interesting. I would imagine with UEFI you would be able to poke that register no matter what was set at uEFI BIOS. Good find.

Corectrl has no support for 5k series atm.

Guess that’s why it doesn’t say the name of my GPU at all.

Thank-you! I noticed on some of my Ubuntu 18.04.6 systems with Ryzen 7-series 2700 and 2700x CPUs after upgrading past kernel 5.4.0-80 that cpufreq stopped working. Sure enough all of these had Cool n Quiet disabled.

Glad it helped
