带 HDMI 输出的 USB-C 集线器无法工作

我最近买了一个带有 HDMI 端口的 USB-C 集线器（QGeeM USB C 集线器多端口适配器，7 合 1），这样我就可以在 Thinkpad E15 上使用两个显示器。

由于某种原因，它无法被自动检测到，因此我无法打开显示器。

xrandr 和 lsusb 输出；

当我插入集线器并记录dmesg时，我确实得到了类似视频输入的东西；

[  287.589762] usb 1-1.4.4: Product: USB C Video Adaptor      
[  287.589764] usb 1-1.4.4: Manufacturer: USB C  
[  287.589767] usb 1-1.4.4: SerialNumber: 000000000001

ThinkPad 表示他们确实通过 USB-C 集线器支持 HDMI。所以我不确定为什么它没有被检测到。

谢谢，乔恩
