ubuntu 18.04 高 CPU/风扇疯狂 - 基本用法

我已全新安装 ubuntu 18.04。我的系统如下：

尽管如此，我还是会不时地遇到 CPU 峰值过高的情况，尽管到目前为止我确实用它来浏览网页和使用 libreoffice。htop我发现：

  • Firefox 消耗了大部分的 CPU，这让笔记本电脑的风扇疯狂。
  • 这样做apt-get upgrade会使 CPU 升高
  • 播放 YouTube 视频时 CPU 使用率超过 50%
  • ETC ...

我可以看看什么东西来了解到底发生了什么事？

答案1

使用内核 4.13.4 解决

  1. 下载并安装尤克里里。
  2. 将此内核放在 GRUB 中的第一位（我使用了 GRUB Customizer）

不再是 100% 的粉丝。
