具有多座设置和 lightdm 的虚拟终端切换

Question

我的目标是为我的 Ubuntu 机器提供两个座位。其中一台显示器是 Mimo 的 USB 触摸屏，带有显示链接芯片。我已经通过重新配置 xorg.conf 让它作为主显示器工作。即使是触摸界面也能工作。

但是对于多席位，仅更改 xorg.conf 是不够的，因为还必须启动其他登录屏幕。这必须进入 lightdm 配置。

通过为 multiseats (lightdm.conf) 配置 lightdm，我设法启动了两个 X 实例，一个用于每个 ServerLayout (xorg.conf)。一个在虚拟终端 7 (VT7) 上运行，一个在 VT8 上运行。众所周知，您可以使用快捷键 Ctrl + Alt + Fx（其中 x 是终端编号）在虚拟终端之间切换。

现在的问题是：默认情况下，VT7 是启用的，而 VT8 是禁用的。但是当我切换到 VT8 时，它被启用但 VT7 被禁用。

如何让两个 X Server 终端/服务器并行运行？

谢谢你。

这是我的 lightdm.conf

[SeatDefaults]
greeter-session=unity-greeter
user-session=ubuntu

[Seat:0]
xserver-layout=default

[Seat:1]
xserver-layout=displaylink

这里只是我的 xorg.conf 的相关部分：

重读https://help.ubuntu.com/community/MultiseatX下的 wiki 条目，我想你应该看看 X 是如何调用的；例如-sharevts，-novtswitch命令行选项应该以某种方式传递给lightdm.conf.

如果您有工作状态，请考虑将 wiki 条目更新到 11.10。
