运行更新后菊花链不再起作用

运行更新后菊花链不再起作用

我正在运行搭载 Ubuntu 18.04 的 Dell Precision 5530,它通过迷你显示端口到显示端口电缆连接到 24 英寸戴尔显示器,该显示器通过显示端口到迷你显示端口电缆使用菊花链连接到 24 英寸戴尔显示器。

直到昨天,一切都按预期进行,但是,我做了一个sudo apt update; sudo apt upgrade,之后菊花链不再起作用了。

所以,一般来说,我有三个显示器

  1. 内置
  2. 24 英寸从笔记本电脑 (1) 连接至此显示器 (2)
  3. 24 英寸从显示器 (2) 连接至该显示器 (3)。

如果关闭 3,1 和 2 会按预期工作,但是,只要我打开 3,甚至 2 都不再工作。2 始终显示在显示下的设置中,但是当 3 打开时为黑色。3 从未出现在设置中。

这是今天早上的更新日志

这适用于 X11 和 Wayland。我执行的步骤

  • 重新插入电缆
  • 关闭/打开监视器
  • 重新开始
  • 登出

更新:我刚刚升级到 Ubuntu 18.10,希望这能解决问题,但是问题仍然存在。
