Changing Screen Resolution

[San Goldberger]

Just Installed Ubuntu, very impressed so far. But having trouble changing my
screen resolution to somthing normale.  Just after installing Ubuntu it was
fine untill I downloaded all the updates and driver for my Nvidia graphics
card. Since restart system has been teribble to work with. Under SYSTEM
PREFRENCES, Screen Resolution, it only gives me an option up to 640x480 Max

Please any help will be appriciated.
