我需要一些帮助。几个月前,我在我的笔记本电脑(HP 15-CS1022NL)上安装了 Ubuntu,其规格如下:
英特尔 i7 第 8 代
16GB 内存
512GB 固态硬盘
Nvidia GeForce GTX 1050
自从第一次安装(Ubuntu 18.04 到现在的 Ubuntu 19.10)以来,我就遇到了问题。系统似乎在滚动、网页导航等简单操作中滞后。这种情况不是随时都会发生的。有时我启动我的电脑,它没有问题,没有滞后,一切都运行良好。我不知道为什么会这样。
另一件要与您分享的事情是:Ubuntu 安装在与 Windows 双启动的 SSD 上(我不知道这是否重要)并且我注意到,也许,在从系统挂起唤醒或关闭并重新打开盖子后似乎会出现滞后。
你能帮我吗?我能检查一下是否有问题吗?
如果需要的话我可以和你分享更多信息。谢谢。

sudo sysctl vm.swappiness=10
这不管用。
从top
命令中我注意到有许多进程的 CPU 使用率很高:
- 韓國:当我使用 Firefox 和 IntelliJ 等应用程序并快速(有意)滚动屏幕时,它会冻结 1 或 2 秒,我可以从 top 命令中看到 Xorg 的 CPU 平均使用率为 80%(最高为 100%)。
- 网页内容:使用 Firefox 时很多时候会出现 CPU 使用率达到 70%(平均)的情况。
这可能是问题吗?

我的问题没有解决,因为我没有找到原因。
但是我现在安装了 Ubuntu 18.04,它似乎没有出现延迟问题。

从几天前开始,Ubuntu 18.04 也出现了延迟问题。有时候有,有时候没有。
