Get higher screen resolution with NVIDIA drivers in Ubuntu

This is a problem I have with my PC, Ubuntu and Nvidia drivers after every installation I do a new version of Ubuntu.
My desktop PC has an integrated graphics card Nvidia GeForce 6150SE nForce 430, the problem arises after Nvidia drivers installed, and I can not get a higher resolution than 1024×768, someone will say it is a resolution so low but for me that I get to use 1280×
