环境：archLinux + i3wm

台式电脑连接两块显示器，i3wm 需要使用 xrandr 命令指定输出到其他显示器，但是每次开机后 xrandr 结果是不固定的，在两种情况下徘徊。因此我在 i3wm 的配置文件需要常常切换，具体配置如下所示：

## multi monitors
#exec --no-startup-id xrandr --output DP-3 --primary
#exec --no-startup-id xrandr --output DP1 --auto --left-of DP-3 --mode 1920x1080 --rotate normal
#workspace 1 output DP1
exec --no-startup-id xrandr --output DP-2 --primary
exec --no-startup-id xrandr --output DP3 --auto --left-of DP-2 --mode 1920x1080 --rotate normal
workspace 1 output DP3

目前的 xrandr 结果如下所示：

Screen 0: minimum 320 x 200, current 3840 x 1080, maximum 16384 x 16384

请教各位，有啥好办法？
