我目前正在尝试将我的新显示器 Samsung C34H890 (LC34H890WGIXCI) 连接到 Linux 笔记本电脑，但这不起作用。我尝试了相同的设置，但使用 Windows 而不是 Linux，一切正常，因此我相信电缆很好，笔记本电脑和显示器都支持这一点。根据我的研究，我需要加载一个内核模块，我这样做如下
sudo insmod /lib/modules/5.7.0-050700-generic/kernel/drivers/usb/typec/altmodes/typec_displayport.ko
# Not sure if the following one is needed
sudo insmod /lib/modules/5.7.0-050700-generic/kernel/drivers/usb/typec/altmodes/typec_nvidia.ko
然后，
[vova]## lsmod | grep type
typec_nvidia 16384 0
typec_displayport 16384 1 typec_nvidia
现在，当我尝试连接监视器时，我可以看到如下日志

我不知道 USB 是如何工作的，也不知道如何调试它以及进一步寻找什么。也许有人可以给我一些有用的提示或参考。也许驱动程序工作正常，但 X11 运行不正常？
如果这不是此类问题的正确资源，请告诉我，并提前致谢。
