Ubuntu 18.04 上带有第二个 Apple 屏幕的 imac

Ubuntu 18.04 上带有第二个 Apple 屏幕的 imac

经过两周的测试,仍未找到解决方案,我决定寻求帮助。我将总结我的情况。

imac 27" (from 2014) + Thunderbolt display 27" + Linux

当我过去使用 Ubuntu 14.04 LTS 时它运行良好,但经过一些更新后,第二台显示器无法工作。

因此,我决定清理我的电脑并安装全新的 Ubuntu 18.04 LTS。

在使用实时 USB 安装期间它可以工作,但重新启动后它就关闭了。

我确实需要第二个屏幕,因此我感谢专家的任何帮助。

一些说明:

  1. 显示器通过雷电线缆连接(像这样),扬声器和 USB 均正常工作。只有屏幕关闭。

  2. 我尝试使用驱动程序:nvidia-driver-390nvidia-driver-340xserver-xorg-video-nouveau

  3. 我仍然有更新了 MacOS Mavericks 的分区,并且那里一切运行良好。

一些额外的信息
