我一直无法让它工作，只是第二个指针出现并闪烁。请注意，我有双显示器、单 GPU 布局。我不确定问题是否与 XOrg 配置（如图所示）无关。任何和所有的帮助和鼓励表示赞赏。谢谢你。
这是xinput插入无线USB设备的情况。
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Microsoft Microsoft® Nano Transceiver v2.0 id=10 [slave pointer (2)]
⎜ ↳ Microsoft Microsoft® Nano Transceiver v2.0 id=11 [slave pointer (2)]
⎜ ↳ PixArt USB Optical Mouse id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]

然后我输入以下命令，并查看结果xinput，我看到屏幕上的另一个指针，无论是光标还是标准指针，它正在闪烁，并且当我在第一个有线 USB 键盘上键入时它会抖动，但是无线设备的触摸板或键盘均未按预期工作。这是一款 Microsoft 一体式媒体键盘。我正在使用 Ubuntu 18.04.1（我觉得我应该注意我从一开始就选择了“最小安装”。）可能还需要注意的是，我正在使用来自 1 个 16 通道 GPU 的两台显示器。感谢您提供的任何帮助。

刚注意到右边的电源开关。很好。
