當我使用 Windows 8.1 時，有一個「高效能」電源選項，可以以犧牲電源為代價獲得更高的效能。

有沒有辦法在 Linux 上將電源選項設定為「高效能」？

答案1

若要查看可用的調速器，請使用下列命令：

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors 
performance powersave

如果您確實有多個調控器，您可以使用下列命令檢查目前正在使用的調控器：

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
powersave

要將您的處理器更改為表現模式使用：

$ echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
performance

然後，您會注意到 CPU% 利用率下降約 5%，但也會注意到速度將從約 1000 MHz 增加到 3000 MHz，溫度將飆升約 10 度，具體取決於您的處理器：

我注意到即使設置為節能Ubuntu 首次啟動時運行的模式（我一直使用的）表現模式持續 90 秒，然後最終啟動節能模式。

儘管如此，使用上面相應的命令手動將調速器設定為性能模式後。現在，它已在效能模式下停留了 10 分鐘，透過使用上面的相應命令進行了確認，並透過上面的 conky 顯示進行了雙重確認。

我讓調速器打開performance了 30 分鐘，效果很好。一些讀者可能會對關閉電源時 conky 顯示器的外觀感興趣表現調速器恢復預設值節能州長：

CPU% 使用率飆升了 5%，但 CPU 頻率下降了 1500 MHz，溫度下降了約 10 度。總的來說我認為節能模式最適合大多數配置。

2019 年 4 月 12 日 - 有人請求康基程式碼，所以我包括今天的版本。目前刷新率設定為 2.5 秒，而 .gif 中的刷新率可能為 1 秒或 0.75 秒。我在這裡編輯了一些程式碼，因為我的設定是為三台顯示器設定的，而大多數人只會擁有一台顯示器。

儲存部分有點棘手。您需要將裝置名稱變更為您自己的裝置名稱，if如果未安裝分割區，則會進行測試，顯示快取和緩衝區等系統資訊。

conky 截圖的下半部分

剛剛注意到上面的 conky 圖像只是上半部分。下半部分包含在下面，因此程式碼更有意義。另請注意，英特爾 iGPU 之前出現過，因為prime-select intel已被使用。此處出現 nVidia GPU，因為prime-select nvidia已使用：

答案2

您可以使用以下命令安裝 CPU 頻率控制器：

    sudo apt-get install indicator-cpufreq

然後重新啟動，轉到通知區域（頂部面板的右側），點擊 cpu 頻率指示器，然後選擇效能。

答案3

將其放在方便的地方~/.bashrc或~/.zshrc

alias cpugetavail='cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_governors'
alias cpushowcurrent='cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor'
alias cpusethigh='echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor'

答案4

Indicator-cpufreq 似乎是最簡單的答案，但我不太喜歡工作列整合。如果您使用的是 gnome，我只是想為inder-cpufreq 提供一個更好的前端提示。 “CPU 電源管理器”，它可以讓您直接從 gnome 工作欄設定最小和最大 cpu。
