如何设置双显示器？

我无法让第二台显示器工作。它被检测到但一片漆黑。屏幕截图捕获了两个桌面。它们在 Windows 中工作正常。我想跨越桌面，我尝试在 Nvidia 面板中使用“新屏幕配置”，然后启用 Xinerama，但没有任何效果。我也找不到 TwinView 的选项。如果我将另一台（右）显示器设置为默认显示器并打开/关闭显示器，我可以让另一台显示器工作，但左显示器是黑的。

规格：i7 5820k、GTX 970、32GB RAM 操作系统：Ubuntu 16.10 驱动程序：Nvidia 367.57 显示器：Dell U2715H (1440p) x2 通过 DP 菊花链连接

截屏

答案1

最好的解决方案是这个命令： xset dpms force off

运行命令后，屏幕进入休眠/黑屏状态，移动鼠标，两个显示器都可以工作。我将其添加到启动应用程序中，以简化操作。
