Method 2: Edit the configuration file

Edit xorg.conf, add the following options to close xscreen saver directly:

Section “ServerFlags”
   Option “BlankTime” “0″    #关闭黑屏
   Option “StandbyTime” “0″   #关闭待机功能
   Option “SuspendTime” “0″   #关闭睡眠功能
   Option “OffTime” “0″
EndSection

Restart after modification and it will take effect.

Editing the xorg.conf file has the same effect as using the xset command. You can use xset -q to view the settings and current configuration.

# xset -q         //查看设置和当前配置
# xset -dpms      //Energy Star features off
# xset +dpms      //Energy Star features on
