当我使用 Windows 8.1 时,有一个“高性能”电源选项,可以以电源为代价实现更高的性能。
有没有办法将 Linux 上的电源选项设置为“高性能”?
答案1
要查看可用的速度调节器,请使用以下命令:
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
performance powersave
如果您有多个调控器,您可以使用以下命令检查当前正在使用的调控器:
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
powersave
将处理器更改为表现模式使用:
$ echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
performance
然后您会注意到 CPU% 利用率下降了约 5%,但同时会注意到速度会从约 1000 MHz 增加到 3000 MHz,并且温度会飙升约 10 度,具体取决于您的处理器:
我注意到,即使设置为节能Ubuntu 首次启动时,它以以下模式运行(我一直使用这种模式)表现模式持续 90 秒,然后最终进入节能模式。
尽管如此,在使用上述适当的命令手动将调节器设置为性能模式后,它已经保持在性能模式 10 分钟,这可以通过使用上述适当的命令进行确认,并通过上述 conky 显示进行双重确认。
我让调速器打开了performance
30 分钟,它工作得很好。一些读者可能会对关闭时 conky 显示屏的样子感兴趣表现州长恢复默认节能州长:
CPU% 利用率飙升了 5%,但 CPU 频率下降了 1500 MHz,温度下降了约 10 度。总体而言,我认为节能模式对于大多数配置来说都是最佳的。
Conky代码
2019 年 4 月 12 日 - 有人请求康基代码,所以我包括了今天的版本。今天的刷新率设置为 2.5 秒,而在 .gif 中,刷新率可能是 1 秒或 0.75 秒。我在这里对代码进行了一些编辑,因为我的设置为三台显示器,而大多数人只有一台显示器。
存储部分有点棘手。您需要将设备名称更改为您自己的名称,并且if

使用了。这里出现 nVidia GPU 是因为prime-select nvidia
使用了:
答案2
您可以使用以下命令安装 CPU 频率控制器:
sudo apt-get install indicator-cpufreq
然后重新启动,转到通知区域(顶部面板的右侧),单击 CPU 频率指示器,然后选择性能。
答案3
将其放在你的~/.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 似乎是最简单的答案,但我不太喜欢任务栏集成。如果您使用 gnome,我只想给出一个更好的 indicator-cpufreq 前端提示。“CPU 电源管理器”,它让您直接从 gnome 任务栏设置最小和最大 CPU。
