我有 3 台可用的显示器，我想合并其中 2 台，以便在最大化应用程序时，它们可以在这 2 台显示器上全屏显示。
我试过用xrandr，xrandr --setmonitor Joined auto HDMI-0,DP-4但没用
我尝试过使用 Nvidia 设置及其功能xinerama，但我觉得它有很多错误，让我损失了一些脑细胞。
我尝试过使用，Compiz但调整屏幕分辨率并没有改变任何东西。
xrandr --verbose输出：

答案1
有两种方法可以实现--setmonitor，但我遇到了同样的问题，即列出所有显示器来创建虚拟显示器不起作用。我发现通过列出显示器的规格然后将其分配给物理显示器来创建虚拟显示器对我来说是可行的……就像这样
xrandr --setmonitor "monitor_name" "width_px"/"width_mm"x"height_px"/"height_mm"+"x_offset_px"+"y_offset_px" "output_name"
