在網上查閱了相關的資料,有下面幾種方法: 1、setterm -blank 0 這種方法在這篇博客中偶詳細的描述,但是在實際操作中並未生效。 Linux LCD 10分鐘黑屏,十分鐘黑屏,LCD自動關閉,LCD黑屏 問題 2、安裝 2.6.2程序防止系統進入黑屏

這個方法沒有嘗試,這個必須在gnome環境下才使用,但是借助這種思路找到第三種方法

安裝 Caffeine方法如下:

安裝方法:   
sudo add-apt-repository ppa:caffeine-developers/ppa   
sudo apt-get update   
sudo apt-get install caffeine   
卸載caffeine命令:  
      
  sudo apt-get remove caffeine  
      
  移除PPA:  
      
  sudo apt-get install ppa-purge  
sudo ppa-purge ppa:caffeine-developers/ppa

3、Disable screensaver in ubuntu

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

sudo vi /etc/X11/xorg.conf

This effectively disables power management on your monitor Settings

Section “Monitor”

#other options can go here

Option “DPMS” “false”

EndSection

Save and exit the file and restart your machine

Solution 3

gconftool-2 --set /apps/gnome-screensaver/idle_activation_enabled --type=bool false

gconftool-2 --set /apps/gnome-power-manager/ac_sleep_display --type=int 0

Solution 4

gnome-screensaver-command –inhibit
