Finally, I enabled my laptop's external monitor (with Intel 855GME integrated graphic card), thanks to Jim Farrand's excellent info. The web addresses are (WOW, I have to write 5 posts to use URL on this forum. This is my first post. I can't use it.)

Due to Intel's video bios problem (for dual head configurations), I should keep "CRT,LFP" for my external LCD and internal LCD.
"LFP,LFP" is not working.
"CRT" means the external monitor including LCDs.
"LCD" stands for the internal LCD of the laptop.
The key points are in the "Device" sections.
The lines in red are crucial.
Code:
Section "Device"
Identifier "Videocard0"
Driver "i810"
BusID "PCI:0:2:0"
Option "MonitorLayout" "CRT,LFP" #this is the important option
Option "VBERestore" "false"
Option "DevicePresence" "false"
Option "DisplayInfo" "false"
Screen 0
