sudo cpupower frequency-set -g performance ``` 在这行代码中: - `sudo`:以管理员权限执行命令,确保能够修改CPU参数。 - `cpupower frequency-set`:`cpupower`工具的命令,用于设置CPU频率。 - `-g performance`:设置CPU的性能模式为performance,即最大性能模式,适合需要更高性能的应用程序运行。 ### 总结 ...
for example because of hardware which cannot be set to a specific frequency or because the userspace governor isn't loaded? 解决方法: 1. 在/etc/default/grub中加入 GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=disable" 2. 命令行输入: grub2-mkconfig -o /boot/grub2/grub.cfg ...
After installation, click on the CPU icon in the top bar of your Gnome shell and follow the instructions. You need to enter your root password to install a policy kit rule. This rule is used to set the clock frequency of your CPU. ...

using those tools until 2021 to set my governor to powersave the summmer months. Then I discovered linux-cpupower, which I used by running "cpupower frequency-set -g powersave" on every boot. I was also annoyed by the lack of a systemd service and a config file in ...
> frequency-set -g powersave" on every boot. Hi! How did you use to run "cpupower frequency-set -g powersave" ? Manually? Or did you drop that line in some script executed at boot (such as the deprecated rc.local)? If I understand correctly, it was working, without failing, when...
“Attempt Installation”, you’ll get a password prompt. The extension needs root privileges to add policykit rule for controlling CPU frequency. Enter the sudo password and click“Authenticate”, and that finishes installation. The last action adds a policykit file -mko.cpupower.setcpufreq.policy...
