It sounds like ( a joke. get it) your Modeline
settings got changed when you did the install. I would
look at http://www.ltsp.org/contrib/modelines.html for
some safe settings. If you know your monitors V and H
refresh rates, and would like to optimize your
settings, google around for a modeline calculator.
