cpufreqドライバーをintel pstateからacpiに変更します。

Intel pstate cpufreqドライバーを無効にして、最大のCPU制御を取得するためにそれをacpiに置き換えようとしています。私はこれを試しました。

vim /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=disable quiet splash"
or 
GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=disable" in a separate line
grub-mkconfig -o /boot/grub/grub.cfg
No change so i reboot
reboot

Sudo service cpufreqd restart
Sudo modprobe acpi-cpufreq

私がする時 cpufreq-infoそれでも表示されます

/ etc/default/modules/acpiをmodules = "all"に編集してモジュールをロードして再起動しようとしましたが、機能しません

ここで何が悪いのですか？

intel_pstate ACPIドライバーよりもきめ細かい方法で互換性のあるCPUを管理するため、一般的には、ACPIドライバーに処理を任せた方がよいでしょう。

最近のカーネルでは、ブート後にそれを無効にできる場合があります。これを行うには、 write off to /sys/devices/system/cpu/intel_pstate/status ;これが成功した場合（制限についてはドキュメントを参照）、ACPIドライバを代わりに使用できるはずです。これを機能させるには、HWPを無効にする必要がある場合があります。これを行うには、カーネルブートパラメータにintel_pstate=no_hwpを追加します。

（ドキュメントには、intel_pstate=disableが登録をまったく妨げるべきであると記載されているため、それが機能しないという事実は多少意外であり、バグを示している可能性があります。）
