Display distorted after OS upgrade

Hi there,
I have Dell Latitude E6400, recently I upgraded from Ubuntu 13.04 to Ubuntu 13.10 then after the first boot, my resolution got weirdly distorted, its stuck on one corner of the screen and the options are only showing one option 640 x 480, on Ubuntu 13.04 everything was okay, what could be causing this kind of problem? Restarting won't solve the problem, even fresh installation.
