这个问题最近才发生。之前，我的设置很棒。我可以拥有 2 个外部显示器并关闭笔记本电脑的盖子。但现在，当我连接显示器并与扩展坞一起工作时，如果我关闭笔记本电脑（因为我只想使用 2 个外部显示器），一切都会冻结。我有时会在显示器上看到鼠标，但仅此而已，其他一切都是黑色的并且没有响应。
我运行的是 Ubuntu 20.04。我已卸载并重新安装 Displaylink（我使用的是可插拔坞站）。我删除了monitor.xml 文件（这有一点帮助，以便两个监视器都能正确连接）。据我所知，我的 Nvidia 卡是“prime”。我已尝试安装正确的驱动程序，但这并没有产生任何影响。 （NVIDIA GeForce RTX 2070）
这是日志的样子，但我无法取得进展：
