我有这个IOGear GCS22U 2 端口 KVM 切换器我用它在我的 Manjaro 机器 (Linux manjaro 5.10.56-1-vfio-lts) 和我的 Windows 10 机器之间切换。我使用的是 Corsair K95 RGB 键盘和 Logitech G403 HERO 鼠标。
当切换到Windows机器时，它会立即检测并使用键盘。当我的 Linux 系统检测到它时，让我们运行 1/2 秒，重新连接，重复此操作两次，然后像正常一样运行。我想知道有没有一种方法可以让 Linux 仅重新连接一次并且是即时的？类似于始终加载硬件配置的东西？
这种影响似乎是在鼠标上，因为光标具有这种连接/断开效果。而键盘在该周期完成（2 秒）之前不允许使用。
Dmesg -w在（重新）连接 KVM 切换器后，键盘/鼠标工作完成的最后几行输出：

答案1
您的问题可能与每当您将 KDM 切换到 Linux 时 Linux 都需要加载设备驱动程序有关。要检查这一点，请执行以下操作：
打开终端。进入dmesg -w。该程序将显示所有启用和禁用的设备的日志。 （尝试插入 USB 驱动器或类似设备，看看会发生什么）。
现在您可以使用该工具来真正了解执行 KVM 切换时会发生什么情况。希望您会看到一个或多个驱动程序正在加载和卸载。如果是这样，您需要查看是否可以将这些驱动程序永久加载到内核中。有多种方法可以做到这一点，一些快速的谷歌搜索至少应该将您推向正确的方向。
