我无法使用我的新笔记本电脑（配备英特尔酷睿 i7-4810MQ 四核处理器 3.7 GHz 的 HP ZBook 15 G2）来避免在 Ubuntu 20.04 上显着限制我的处理器。
它最初在 400MHz 以下开始。我尝试将 Intel-Pstate 的调控器设置更改为性能，我尝试禁用 Grub 上的调控器。我在网上找到了一堆尝试过的建议。
我最后一次尝试让我将 CPU 调控器完全切换到 acpi-cpufreq 调控器，并将其设置为性能或按需。这确实有效果，但现在它的最大频率设置为 900MHz。我尝试使用 cpufreq-set 手动更改它也没有成功。
任何帮助将不胜感激，因为我真的遇到了性能问题。是否还有其他没有此问题的 Linux 发行版？
这是我目前的频率
这是当前的 cpufreq-info 输出，看看它是如何设置为只有 900MHz

任何帮助将不胜感激，机器实际上无法使用这么低的速度。
韦尔普，它是固定的。我很高兴这个问题得到了解决，但它被神秘地解决了。
尝试尝试@Doug Smythie 的回答并重新启用 intel-pstate 调节器并重新启动，我的处理器现在以几乎完全的处理能力以最佳方式工作。
我所要做的就是 /etc/default/grub 文件并将 GRUB_CMDLINE_LINUX_DEFAULT 更改为 GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=enable quiet splash"
一旦我重新启动并测试了我的 CPU 速度，它就很好了。重启几次就卡住了。
神秘的是，这是我以前使用的州长，我以前无法得到这些结果。感谢所有的帮助。
这里没有任何帮助。20.04。
'cpufreq-set -r --governor performance' dosnt 什么都不做，也无助于删除'ondemand'。
它只是继续节流。

我怀疑这些各种 cpufreq 软件正在导致您的节流问题。使用首选项或配置文件来定制您的需求。
或者，至少暂时卸载这些，然后重新测试您的计算机的性能。
