我无法使用我的新笔记本电脑（配备 Intel Core i7-4810MQ 四核处理器 3.7 GHz 的 HP ZBook 15 G2）来避免在 Ubuntu 20.04 上严重限制我的处理器。
它最初以低于 400MHz 的速度启动。我尝试将 Intel-Pstate 的调节器设置更改为性能，我尝试在 Grub 上禁用调节器。我在网上找到了很多尝试过的建议。
我最后一次尝试将 CPU 调速器完全切换为 acpi-cpufreq 调速器，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，但没有成功。
任何帮助都将不胜感激，因为我确实遇到了性能问题。还有其他没有这个问题的 Linux 发行版吗？
这是我当前的频率
这是当前的 cpufreq-info 输出，看看它是如何设置为仅 900MHz 的

如能得到任何帮助我们将非常感激，速度这么低，机器实际上根本无法使用。
答案1
好了，问题解决了。我很高兴问题解决了，但它的解决方式很神秘。
尝试@Doug Smythie 的答案并重新启用 intel-pstate 调节器并重新启动，我的处理器现在以几乎全部的处理能力最佳地运行。
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"
重启后测试了 CPU 速度，一切正常。重启几次后，一切正常。
奇怪的是，这是我之前使用的 Governor，之前我无法获得这些结果。感谢大家的帮助。
答案2
这里没有什么帮助。20.04。
‘cpufreq-set -r --governor performance’ 不执行任何操作，也无助于删除‘ondemand’。
它只是不断地节流。
答案3
CPU频率
dpkg -l *freq* | grep ii 的结果
ii cpufreqd 2.4.2-2ubuntu3 amd64 fully configurable daemon for dynamic frequency and voltage scaling
ii cpufrequtils 008-1.1 amd64 utilities to deal with the cpufreq Linux kernel feature
ii indicator-cpufreq 0.2.2-0ubuntu3 all CPU frequency scaling indicator
ii libcpufreq0 008-1.1 amd64 shared library to deal with the cpufreq Linux kernel feature
我怀疑这些不同的 cpufreq 软件导致了您的节流问题。使用首选项或配置文件来满足您的需求。
或者，至少暂时卸载这些，然后重新测试计算机的性能。
sudo apt-get purge cpufreqd cpufrequtils indicator-cpufreq libcpufreq0
reboot

在 Ubuntu 20.10 中 CPU 时钟固定在 800MHz这个答案帮助我解决了 Ubuntu 20.04 中搭载英特尔 i7-10510U CPU 的 Latitude E3410 上的问题。
我刚刚卸载了thermald使用sudo apt autoremove thermald，一切又开始正常工作了。
