这种方法在这篇博客中偶详细的描述，但是在实际操作中并未生效。
Linux LCD 10分钟黑屏，十分钟黑屏，LCD自动关闭，LCD黑屏 问题
2、安装 2.6.2程序防止系统进入黑屏
这个方法没有尝试，这个必须在gnome环境下才使用，但是借助这种思路找到第三种方法 安装 Caffeine方法如下：安装方法：
sudo add-apt-repository ppa:caffeine-developers/ppa
sudo apt-get update
sudo apt-get install caffeine
卸载caffeine命令：
sudo apt-get remove caffeine
移除PPA：
sudo apt-get install ppa-purge
sudo ppa-purge ppa:caffeine-developers/ppa

Solution 1:
Edit /etc/X11/xorg.conf file using the following command
sudo vi /etc/X11/xorg.conf
Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
EndSection
and add the following lines
Section “ServerFlags”
#other options can go here
Option “BlankTime” “0″
Option “StandbyTime” “0″
Option “SuspendTime” “0″
Option “OffTime” “0″
EndSection
Save and exit the file
Solution 2
Edit /etc/X11/xorg.conf file using the following command

EndSection
Save and exit the file and restart your machine
