我的新笔记本电脑和 Thunderbolt USB-C 基座存在问题。笔记本电脑是 HP Elitebook 865 G9，基座是 Hama 200100 10 端口基座，带有 2 个 HDMI 和 1 个 DisplayPort（以及各种 USB 和以太网端口）。
我使用 Ubuntu 22.04 作为操作系统，内核为 5.15.0-46-generic #49-Ubuntu SMP Thu Aug 4 18:03:25 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
该系统配备有集成 AMD 显卡的 AMD Ryzen 7 6850U CPU。
我的问题是，我无法让两个 HDMI 显示器通过 Hama USB-C 扩展坞工作。在启动期间，我可以在两个显示器上看到镜像，但系统启动后，其中一个显示器仍然空白。但是，在显示设置中，我可以看到两个显示器都处于活动状态，xrandr 命令也显示两个显示器都已连接，但是在一个显示器上没有 HDMI 信号。我尝试用谷歌搜索，但不幸的是，还没有找到解决此问题的任何方法。似乎是一些与 AMDGPU 相关的问题，但是我发现了一些有关多个 USB-C 视频输出的补丁，这些补丁应该已经在内核中作为修复程序（检查了补丁提交和我正在运行的当前内核的源代码）。
不知道如何克服这个问题，如果两个显示器都能工作就好了。

答案1
经过一番折腾和大量调查（更新了 BIOS，尝试了各种 BIOS 设置等），我尝试使用 Ubuntu Mainline Kernel 安装程序安装最新的内核（5.19.5-051905-generic），成功了。看来要么是我的主板/GPU/CPU 对于 5.15 内核来说太新了，要么是 Thunderbolt 底座/多个 HDMI 输出方面已经修复了一些错误，无论如何，现在两个显示器都可以正常工作了。
