三显示器、双卡和 Openbox 问题

我在 2 个视频卡（nvidia 和板载 intel）上设置了 3 个显示器，它们都正常工作，但不是我想要的那样。当只有 nvidia 上的 2 个显示器时，Openbox 会将它们视为单个桌面/工作空间，但仍然是单独的显示器，并允许我仅在该显示器上全屏显示应用程序。现在我有另一张卡和显示器处于活动状态（在其自己的 xserver 上），2 个 nvidia 显示器充当单个屏幕，应用程序在两个显示器上全屏显示。GDM 单独处理每个显示器（登录提示以 Screen0 为中心，Screen1 有壁纸，Screen2 只是普通的 X），但一旦我进入 openbox，nvidia 的合并，将所有内容置于它们和 intel 之间的中心，表现正常。有人知道如何保留 nvidia 屏幕的双显示器行为吗？

我的 xorg.conf：

在附件中，您可以找到一个有效的 xorg.conf.d：“zaphod 模式”= 四个独立的屏幕，例如与 twm、fluxbox、xfce 一起工作。

不幸的是，对我来说，最新的 Openbox x11-wm/openbox-3.6.1（Gentoo）也只在屏幕 0.0 上打开了一个可工作的桌面环境 - 0.1..0.3 仍然空白，尽管“xrandr -q --screen 0.n”提供了正确的结果。
