我试图弄清楚使用 xdotool 时 --screen 的值来自哪里，但我似乎无法使用 xrandr 找到该值。
我将在下面粘贴 xrandr 的输出，但“HDMI-0”实际上是 xdotool 的“--screen 2”，而“DP-0”是“--screen 0”。我猜 X 是按照 DP-0、DP-1、HDMI-0 然后是 DVI-D-0 的顺序进行轮询的……但我不知道 X 将这些关联存储在哪里（或者即使 X 以这种方式进行轮询是正确的）。
“HDMI-0”的工作示例：xdotool mousemove --screen 2 50 50 click 1
Screen 0: minimum 8 x 8, current 3600 x 3840, maximum 32767 x 32767
DVI-D-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 connected primary 1440x2560+2160+1200 left (normal left inverted right x axis y axis) 596mm x 335mm
