xcalib显示编号/屏幕编号

我正在尝试使用 xcalib 来降低显示器的对比度。这是我的 xrandr 的输出。

Screen 0: minimum 8 x 8, current 3840 x 1200, maximum 32767 x 32767
DVI-D-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 527mm x 296mm
   1920x1080     60.00*+
   1680x1050     59.95  
   1600x900      60.00  
   1440x900      59.89  
   1280x1024     75.02    60.02  
   1280x720      60.00  
   1024x768      75.03    60.00  
   800x600       75.00    60.32  
   640x480       75.00    59.94  
HDMI-0 connected 1920x1200+1920+0 (normal left inverted right x axis y axis) 518mm x 324mm
   1920x1200     59.95*+
   1920x1080     60.00  
   1680x1050     59.95  
   1600x1200     60.00  
   1280x1024     60.02  
   1280x960      60.00  
   1024x768      60.00  
   800x600       60.32  
   640x480       59.94  
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)
DP-3 disconnected (normal left inverted right x axis y axis)
DP-4 disconnected (normal left inverted right x axis y axis)
DP-5 disconnected (normal left inverted right x axis y axis)

到目前为止，我可以使用此命令按比例更改两个显示器的对比度 -

xcalib -co 80 -a #reduces contrast by 80 percent.

如何指定监视器名称？

xcalib -co -80 -d DVI-D-0

抛出错误 - 无法打开显示

From Trial and errorxcalib的-screen参数根据您的输出获取显示器的零索引号xrandr，即，在您的情况下xcalib -s 0（默认） will controlDVI-D-0和xcalib -s 1will control HDMI-0。
