I have an old Dell Latitude D600 and since a recent update, the maximum screen

Do you have the S-Video connector in? This section seems to say you have, and that the maximum resolution isn't 1024x768. Try unplugging it and logging out then back in.

It's just a guess, since I don't have an ATI card.
