我想获取当前显示器的分辨率(运行脚本的屏幕)或屏幕名称(LVDS、VGA1 等)。
如果我无法获得分辨率而只能获得显示器名称,我可以 grep 'xrandr -q' 输出以获得当前分辨率。
提前致谢。
您应该能够通过组合来做到这一点xrandr和xwininfo。
获取屏幕、它们的分辨率和偏移量:
$ xrandr | grep -w connected | awk -F'[ \+]' '{print $1,$3,$4}'
VGA-0 1440x900 1600
DP-3 1600x900 0

$ xwininfo -id $(xdotool getactivewindow) | grep Absolute
Absolute upper-left X: 1927
Absolute upper-left Y: 70

#!/usr/bin/env bash
## Get screen info
screen1=($(xrandr | grep -w connected | awk -F'[ +]' '{print $1,$3,$4}' |
head -n 1))
screen2=($(xrandr | grep -w connected | awk -F'[ +]' '{print $1,$3,$4}' |
tail -n 1))
## Figure out which screen is to the right of which
if [ ${screen1[2]} -eq 0 ]
then
right=(${screen2[@]});
left=(${screen1[@]});
else
right=(${screen1[@]});
left=(${screen2[@]});
fi
## Get window position
pos=$(xwininfo -id $(xdotool getactivewindow) | grep "Absolute upper-left X" |
awk '{print $NF}')
## Which screen is this window displayed in? If $pos
## is greater than the offset of the rightmost screen,
## then the window is on the right hand one
if [ "$pos" -gt "${right[2]}" ]
then
echo "${right[0]} : ${right[1]}"
else
echo "${left[0]} : ${left[1]}"

该脚本将打印当前屏幕的名称和分辨率。
