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
