ubuntu 背光键盘 不亮的解决方法

下面是我写的一个脚本。你可以把它加到你的环境变量里面去（比如说我放到了/usr/local/bin目录下）。用法为（假设你给这个脚本起的名字为sl）：

开启背光灯：sl on  或者 sl ON

 关闭背光等：sl off  或者 sl OFF

#!/bin/bash 
 
if [ "$1" = "on" ] ||[ "$1" = "ON" ]; then 
    xset led  named 'Scroll Lock' 
elif [ "$1" = "off" ] ||[ "$1" = "OFF" ]; then 
    xset -led named 'Scroll Lock' 
else 
    echo "Usage: $0 on/off" 
    exit 1 
fi 
exit 0
