拦截电源关机按键、自定义功能

#忽略gnome自带的电源管理

sed -i "s/#HandlePowerKey=poweroff/HandlePowerKey=ignore/g" /etc/systemd/logind.conf

systemctl status systemd-logind

yum install acpid

systemctl disable acpid

#如果以systemctl start acpid方式启动acpid, /etc/acpi/actions/power.sh里的命令只有shutdown -h now能执行成功, 其它命令kill echo touch 均执行不成功, 只能以#acpid启动

/etc/profile尾部添加

########################

alreadyStart=$(ps -elf | grep acpid | grep -v grep | wc -l)

if [  0 == ${alreadyStart} ] ; then

acpid

fi

########################

/etc/acpi/actions/power.sh 删除所有行, 添加自定义关机按键功能, 什么都不写就是屏蔽掉了关机按键功能

在此文件中添加如下几句,实现给screenserver进程发信号,让进程处理此信号(进程内部实现关闭屏幕、关闭操作系统)

########################

#!/bin/sh

PATH=/sbin:/bin:/usr/bin

kill -12 $(ps -elf | grep screenserver | grep -v grep | awk ‘{print $4}‘)
