现在，我已经在装有 Windows 10 Home 64 位的 Packard Bell 上安装了 Ubuntu 20.04 进行双启动，我无法阻止鼠标指针跳来跳去，无论指针移动到哪里都会留下一串闪烁的指针。当我将鼠标悬停在按钮上时，指针会跳来跳去，点击按钮会变得非常不稳定。同时，当我在屏幕上移动第二个指针时，一个不动的指针位于屏幕的右下角。请问我该如何解决这个问题？这是鼠标驱动程序兼容性问题吗？
这是我的xinput的结果：
$ lsb_release -a

我在这里瞎猜。我拔掉了 USB 鼠标，重新插入后，没有任何变化。我还下载了，因为有人说，当他的鼠标指针在升级到 Ubuntu 20.04 后跳来跳去时，这对他的触摸板有效。对他来说有效，但对我不起作用。
这是我下载的内容：
$ sudo apt install xserver-xorg-input-synaptics
因此，看起来我必须将其卸载。
$ sudo apt-get remove xserver-xorg-input-synaptics
删除它之后我收到以下消息：

Package 'xserver-xorg-input-synaptics' is not installed, so not removed

Use 'sudo apt autoremove' to remove them.

因此，我已自动删除不再需要的软件包。它没有改变任何东西。我已将鼠标从 USB 3 拔下，并将其插入 USB 2，但没有任何效果。让我们看看输出：
lsb_release -a; uname -a; lsusb
输出为：

这4e70 USB 光电鼠标未列出。这可能是我的问题吗？
为了尝试回答这个问题，我找到了一个 Xenta 无线光电鼠标，但是仍然存在一个鼠标指针抖动的问题（我可以移动它），而第二个鼠标指针却固定在屏幕右下角。

然而，我认为任何改变都无法解决这个问题。
作为4e70 USB 光电鼠标未列出，在Linux USB ID 列表，但肯辛顿 4d03 盒子里的老鼠是，我要尝试得到其中的一个。
答案1
所以，我在这里解决的所有问题是：
- 这不是 Windows 10 和 Ubuntu 20.04 的双启动设置
- 这不是由于鼠标驱动程序不兼容
然而，当我将另一台显示器连接到我的电脑时，鼠标指针跳跃的问题就出现了 -https://help.ubuntu.com/stable/ubuntu-help/display-dual-monitors.html
