我今天过得非常艰难，一直在努力，但最终却一事无成。我重启了很多次，这让我特别疲惫。
这是xinput插入无线 USB 设备后的情况。
⎡ 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)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Power Button id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ Microsoft Microsoft® Nano Transceiver v2.0 id=9 [slave keyboard (3)]
↳ CHICONY USB Keyboard id=13 [slave keyboard (3)]
↳ CHICONY USB Keyboard id=14 [slave keyboard (3)]
↳ Microsoft Microsoft® Nano Transceiver v2.0 id=15 [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，它都在闪烁，当我在第一个有线 USB 键盘上打字时它会抖动，但无线设备的触摸板或键盘都没有按预期工作。这是一款 Microsoft 一体式媒体键盘。我使用的是 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”。）还值得注意的是，我使用的是来自 1 个 16 通道 GPU 的两个显示器。感谢您提供的任何帮助。
