我在 Dell Latitude E-5470 上运行 Ubuntu 20.04 LTS。我想使用扩展坞，这样我就可以拥有双显示器设置。我分别尝试了 D3100 和 Plugable UD-6950H 扩展坞。这两个扩展坞都使用 DisplayLink 驱动程序。这两个扩展坞都会导致我的机器随机关闭并重新启动。
D3100 站
根据这个帖子（关于 D6000 扩展坞），我已经注释掉load-module module-suspend-on-idle并etc/pulse/default.pa重新启动。
接下来我按照这个 github 帖子，认为也许是所引用的内核更新存在问题。
可插拔 UD-6950H
经过这些尝试和其他一些尝试后，我发现这个博客其中一位 Ubuntu 用户（也使用戴尔 Latitude 系列 PC）讨论将显示链接基座与 ubuntu 连接起来。
我决定尝试一下作者推荐的工作站，于是买了一个可插拔工作站。我用它工作了一整天，没有出现任何崩溃（3 月 14 日），但之后就出现了崩溃。
在其中一次崩溃后，我检查了系统日志，并粘贴在下面。我成为 Ubuntu 用户才大约 6 个月，所以我仍然在学习很多东西。我不知道如何解读这里发生的事情，但我确实看到内核evdi在崩溃时（13:07 - 08）参与其中。
我会非常感激任何能给我指明正确方向的帮助或反馈。我知道这是可以做到的，但我也知道Linux 内核的对接站很难。
提前致谢。
