I'm trying to set my screen resolution to 1024X768 so it fits entirely on my monitor's screen. When I set the resolution to 1024X768 (System-->Preferences-->Screen resolution) my desktop pans larger than my monitor. This is very Inconvenient and not what I want. I can set the screen resolution to 800X600, but that's to small. My video card is an older ATI Rage 128. Has anyone seen and resolved this problem? Thanks in advance.

Here is my xorg.conf:
