我目前正在使用 ubuntu 21.10，而且我对 linux 还比较陌生，所以我不太清楚如何更改东西，但以下是我在不同的论坛上寻求答案时所做的
cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 4.0 us
hardware limits: 800 MHz - 3.20 GHz
available frequency steps: 3.20 GHz, 2.50 GHz, 1.90 GHz, 800 MHz
available cpufreq governors: conservative ondemand userspace powersave performance schedutil
current policy: frequency should be within 800 MHz and 3.20 GHz.
The governor "schedutil" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 1.90 GHz (asserted by call to kernel)
boost state support:
Supported: no
Active: no
我想将其更改为性能，因为操作系统在使用它时会抖动，因为它没有利用 100% 的 CPU 能力，我试着这样做，但得到了一个错误
sudo systemctl disable schedutil
Failed to disable unit: Unit file schedutil.service does not exist.
我不确定如何永久设置性能调节器。
