通过 DisplayLink 的 Manjaro Sway 显示器屏幕无法工作

我正在尝试让 Lenovo DisplayLink 与 Manjaro Sway 配合使用，但到目前为止还无法让屏幕信号通过它。

我将 Linux 更新到内核 5.15
我安装了相应的 linux-headers 以正确安装 evdi
我安装了 displayconnect

当我跑步时

systemctl start displaylink.service

它崩溃了

当我重新登录 shell 并手动启动 sway 时，会出现以下错误：

任何帮助将不胜感激

在我看来，evdi 模块包可能已损坏。如果您是从 Manjaro 存储库安装的，则可以尝试 AUR 版本和相应的 DisplayLink 软件包版本。只需检查您正在安装的 evdi 版本是否与内核兼容即可。如果它不能与主线内核一起工作，您可以尝试 LTS 版本。

作为最后的手段，你可以尝试使用其他 DE，例如 Gnome 和 Wayland，一般来说，在 Wayland 上它应该无需任何额外配置即可工作。在 X 上，需要一些额外的配置，具体取决于发行版。
