I think you need to set the correct horizontal and vertical refresh values for your laptop's monitor and that should fix your problem. You can do this in "dpkg-reconfigure xserver-xfree86" if you choose the "advanced" monitor configuration.

The correct monitor refresh values you should find from the manual that came with your laptop. If the laptop didn't come with a manual or if you've lost it, then you can try installing a hardware probe tool called xdebconfigurator (aptitude --with-recommends install xdebconfigurator). It's far from foolproof but in many cases that's your best available option, so it might be worth trying. ;)

After installing xdebconfigurator, you can "su" to become root and then run the following command:

xdebconfigurator -x

This should output a list of probed info about your display hardware and you can use this info in "dpkg-reconfigure xserver-xfree86".
