Thank Sebastian Ferrara and karlos! Now I have fixed the problem.The cause is the inappropriate setting of the LCD.It's my first time to use a LCD,and I even didn't know Lcd is so different from CRT. After I press "auto",everything is all right!
To Sebastian Ferrara: The i810 driver is Ok.But it seems someone has reported that the i810 just can be used with the LCD that smaller or equal than 17inch(mine is 17inch,so is ok,too ).I have found a article on gentoo-wiki about the configuration of the kernel to use Intel_945G.May be you will be interested.
