Linux开启键盘背光

在Linux中默认是不能打开键盘背光的，按Scroll Lock 没有反应，需要我们使用命令手动启动，话不多说，直接上代码，以下为SHELL脚本：

#!/bin/bash  if [ ! $1 ];thenconn="on"elseconn=$1fi  if [ "$conn" = "on" ] ||[ "$conn" = "ON" ]; then      xset led  named 'Scroll Lock'  echo "Scroll Lock on ok^_^"elif [ "$conn" = "off" ] ||[ "$conn" = "OFF" ]; then      xset -led named 'Scroll Lock'  echo "Scroll Lock off ok^_^"else      echo "ERROR! Pleace run: $0 or $0 on/off"      exit 1  fi  exit 0
