Ubuntu 18.04 上的多座位？

Question

我一整天都在阅读（旧）指南，但我仍然对 Ubuntu 18.04 上的 multiseat 一无所知。更糟糕的是，我只有一张带有多个输出的显卡。

唯一给我希望的是loginctl list-seats我的 Ubuntu 知道座位。

如何在多座中设置我的机器？

编辑： loginctl 命令的输出。

请注意，并非所有东西都相互关联。我想首先弄清楚如何解决这个问题，而不是一头扎进去。我想每个座位都有自己的 USB 集线器（HID 设备 + 任何其他需要的东西）+ 一个显示器。

loginctl list-seats
SEAT            
seat0           

1 seats listed.

loginctl seat-status seat0

seat0

到目前为止，多个视频卡是设置多座位的简单方法。它允许您避免 Xephyr 和任何其他附加配置的混乱。

设置第二个座位（假设您有第二个视频卡）并不比发出命令更简单：

“loginctl 附加座位 1 __________________”

重新启动后，您应该有两个登录屏幕。在此之后，所有其他配置通常是附带的。

您的主板是否支持第二个全长 PCI-E 图形插槽？如果没有，那不是自动取消资格。您还可以使用比特币人群喜欢使用的 PCI-E 1x 竖板之一为您的机器添加 16x 插槽。不是说你应该，我只是说你可以。
