我刚刚收到了我的新戴尔 XPS 9380，预装了 ubuntu 18.04。它很棒，除了两件事之外，一切似乎都运行顺利：
有时在终端中输入内容会使系统冻结 3-4 秒。（我可以看到时钟在顶部栏中停止）。然后，在此间隔内输入的字母将同时出现。似乎这种情况主要发生在按住退格键删除某些内容后，但很难一致地重现。然而，这非常烦人；
有时在使用触摸板时它会停止工作几秒钟，或者在屏幕上跳到某个地方。
我已经对这个问题做了大量的研究，但很难找到 XPS 9380 和 ubuntu 18.04 的具体问题，而且我不想破坏任何东西。（我看到一些人谈论触摸板的设备冲突，以及英特尔显卡性能模式的问题导致的冻结）。我的系统完全是最新的。
不确定是否相关，但这是输出xinput --list
