我有一台安装了 Debian 10（稳定版）的笔记本电脑。我当前的设置是这样的：
我将笔记本电脑的嵌入式屏幕作为一个显示器，一个通过 HDMI 连接的外部显示器，现在我通过以下方式连接了第二个外部显示器（与第一个相同）HDMI-USB3 适配器因为我的笔记本电脑没有任何其他端口，也没有 GPU（仅通过 Intel CPU 芯片集成显卡）。
我已经成功安装了显示链接-debian司机，这是官方 DisplayLink Ubuntu 驱动程序的修改版本，而我的新显示器却找不到。
在这里您可以看到驱动程序的调试（当我安装它时，20-displaylink.conf没有生成该文件。我必须自己将其放入/etc/X11/xorg.conf.d/，/usr/share/X11/xorg.conf.d/然后创建带有调试中打印的信息的提到的文件（我从这里）：

我现在真的没有主意了。 DisplayLink 适配器确实显示，但不显示显示器。我正在尝试对其进行配置，以便拥有更好的工作流程，但什么也没有发生。如果您需要我未提供的任何其他信息，请告诉我，并感谢所有关注我的问题的人。
