我对 Ubuntu/Linux 并不陌生，但离专业人士还差得很远！实际上，我在 Pinebook Pro ARM 笔记本电脑上运行 Ubuntu 22.04（通过 ARMBIAN 安装）和 Gnome 42：
$lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.2 LTS
Release: 22.04
Codename: jammy
$ uname -a
Linux pinebook-pro 6.1.30-rockchip64 #3 SMP PREEMPT Wed May 24 16:32:53 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux
$ gnome-shell --version
GNOME Shell 42.
我尝试过支持 USB-C 的戴尔显示器 (U3421WE)、带有联想显示器的 DELL-USB-C 扩展坞以及带有富士通显示器的联想 Thinkpas 通用 USB-C 扩展坞 (40AY)。
行为总是一样的：USB-Hub 正在工作（鼠标、键盘等），但显示器不工作：
U3421WE 显示：“设备无 USB-C 信号”。其他设备只显示：“无输入信号”。无论是热插拔还是在启动前插入，都无所谓，也不会翻转 USBC 插头。
她（作为示例）提供了一些我认为有用的信息：
