VirtualBox 中的双显示器 Linux 客户机

VirtualBox 中的双显示器 Linux 客户机

我读到较新的 VirtualBox 支持具有双显示器的 Linux 客户机。当我启动 Arch VM 时，我能够启动两个显示器，但我无法让 Xorg 跨越到第二个显示器。它们始终以克隆模式显示。有人成功做到这一点吗？如果有，您可以分享您的 xorg.conf 吗？

编辑：我的 xorg.conf（我尝试使用增量 BusID 作为测试，但之前它们是相同的）。

答案1

我使用 randr 作为解决方法

xrandr --output VBOX1 --right-of VBOX0

我把它放在自动启动中。它会在你登录后运行

答案2

你的 conf 文件中有什么？如果你没有明确告诉它你有多个显示器，它只会克隆输出。如果你不确定如何修改 conf 来做到这一点，有几个很好的教程，比如xorg 架构维基。
