1. Generate xorg.conf：

1.1 After Intrepid installed in text mode by default, reboot and hit right before OS boots. This brings up the Grub Menu for boot option.

1.2 From the available modes, select the one ended with "(recovery mode)" then enter to boot.

1.3 Login as root at prompt in text mode.

1.4 Produce the X configuration file according to your own system
# X -configure
This generates a file named xorg.conf.new under $HOME folder of the user.

1.5 Copy the new xorg.conf to and backup the original one
# cp /etc/X11/xorg.conf /etc/X11/xorg.conf.viabak
# cp $HOME/xorg.conf.new /etc/X11/xorg.conf

2. Get correct resolution argument:

$ gtf horizontal_resolution vertical_resolution refresh >> ~/gtf.txt
Ex: gtf 1280 1024 60 >> ~/gtf.txt

3. Modify xorg.conf section.

Modify xorg.conf：
// Edit or add following lines which start with #, # is for identification only, no need to input # into your config file actually.
