我读过一些有关在第二台显示器上运行应用程序的问题，但建议的选项都不适合我。除此之外，我尝试不仅在第二个显示器上运行不同的应用程序，而且还在第三个和第四个显示器上运行不同的应用程序。
我试过了
export DISPLAY=:0.1
export DISPLAY=:0.2
export DISPLAY=:0.3
export DISPLAY=:0.4
export DISPLAY=:1.1
export DISPLAY=:1.2
export DISPLAY=:1.3
export DISPLAY=:1.4
但它们都不起作用。仅有的
export DISPLAY=:0
适用于显示器 1
但是我发现“export DISPLAY:0”是相对于鼠标所在的显示器而言的。因此，如果鼠标位于显示器 4 中并且我运行“export DISPLAY=:0”，然后运行“eog image”。 jpg' 它在同一台显示器上运行。
这是我正在运行的 xorg.conf 文件。也许有人可以从中获得一些有用的信息。它是由
