Ubuntu 18 LTS 和带有内置 KVM 的 LG 显示器

2024-6-5 • tag-icon

我有一台 LG Electronics UM95 34UM95-P 34 显示器，它内置有 KVM 切换器。我在带有 USB-C（Thunderbolt-3 端口）的 MSI GS 65 Stealth 上运行 Ubuntu 18 LTS。

我的显示器比较旧，支持 Thunderbolt-2，因此我使用 Apple USB-C -> Thunderbolt-2 适配器。这样我就可以将显示器连接到笔记本电脑。

我在笔记本电脑上双启动 Windows 10，此设置在 Windows 上运行良好。当我启动 Ubuntu 时，事情变得有点奇怪。很多时候，只有我的键盘能工作几分钟，然后就停止工作了。我的鼠标（连接到同一个 KVM）从不工作。

关于如何进一步诊断这一点，您有什么想法吗？

这就是lsusb -t告诉我的。
