$ sudo cpufreq-set -g performance
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?

[Mastic_Warrior]

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?

[robbbot]

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).
