Blurry Display

When I run startx my display shows up the the right half of the screen blurry as if the resolution is set too high. I can read the left side of the desktop but the right side is in high-speed scan mode or something. Using ATI Rage IIC AGP PCI card. This is on a new installation of Ubuntu Server 9.04 where the stall and everything else processed great. But starting the GUI is odd. I have been researching and installing several version of Ubuntu, Debia etc and the display was fine with those install but I didn't like the functionality. Any suggestion for this?
