[CentOS] screen shifting

Hello List,

I was wondering if there is a way to shift the screens in linux. I got a kvn yesterday, and have a problem when switching from computers, where the screen is slightly shifted on one of them. I have to go into the monitor configuration screen and move the screen to the right to center it on one of the computers. Then when moving back to the other computer, that screen isn't centered and have to back to the left so its centered. Is there a way to adjust this in xorg.conf so that when I switch between the computers, I don't have to switch the computers? I am running CentOS 4.1.

Thanks,

Dan
