Can you tell us more about your graphics card, drivers (proprietary or free, if you have an ATI or NVidia graphics card), and monitor?
You may also want to try doing 'dpkg-reconfigure xserver-xorg'--follow through the prompts to give it another shot at detecting your monitor. You'll need to restart to see the effect (technically just restart X, but it's probably easiest to restart entirely).
