如何让单独的 x 屏幕多显示器工作

刚刚升级到 14.04，重启后我的辅助显示器无法像升级前那样工作。我尝试让它恢复工作，但这次似乎不起作用。之前我将两个显示器作为单独的 x 屏幕，并通过 Nvidia x 服务器设置进行配置。

现在我的第二台显示器只有黑色背景，没有其他内容。我仍然可以移动光标到它上面，但无法对它执行任何操作。我的 xorg.conf 文件位于本文底部。

有人有什么想法吗？如果您需要更多信息，请直接询问。

更多信息。当我进入“系统设置”>“屏幕显示”时，只检测到我的主显示器。我很确定我的第二台显示器之前在那里。

我刚刚也遇到了同样的情况。我查看了一下/etc/X11，发现我的xorg.conf文件已被重命名，xorg.conf.MMDDYYYY其中 MMDDYYYY 被设置为今天的日期（我升级的那天）。

我将此xorg.conf.MMDDYYY文件复制到/etc/X11/xorg.conf，重新启动，我的第二台显示器恢复了运行。也许你不会这么轻松，但这对我来说很有效。
