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 don’t know what changed, but I’m now suddenly unable to change the CPU governor on my Ryzen 5900X.

Which driver is supposed to be loaded?

You should probably keep this in one thread since it is all related.

There is no driver need to get the governor to work. Like I mentioned in your other post, Have you updated the CPUFreq userspace software but not the kernel driver or vice versa?

What kernel are you on and what is your distro?

Looks like your missing some files that I’m assuming whatever CPUFreq is needs to set those.

From my ~/.bashrc


I’m assuming CPUFreq is probably trying to-do something similar.

I’m also on a 5900x, and this works fine (kernel 5.16.2).
