开机默认亮度
1》首先确定电脑屏幕亮度区间
#:cd /sys/class/backlight/intel_backlight
有三个文件
actual_brightness 最小值
brightness 当前值
max_brightness 最大值
2》 确认亮度区间后
#:vi /etc/rc.local
#!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. #添加如下一行命令,103必须在亮度区间内。 echo 103 > /sys/class/backlight/intel_backlight/brightness exit 0
退出保存即可!执行关机,然后启动亮度值及改变。切记不是重启。
2.不至此exfat格式U盘
