Screen Resolution

I have installed Linux Redhat Enterpeise ES version 3 on a Dell Poweredge 2850. I am running the Gnome desktop.  When the resolution is set to 640 x 480 the icons are huge.  When I change the resolution to 1024 x 768 the dsiplay does not fit the screen.  It's like the screen goes beyond the edge of the display and I have to move the mouse to see from one side to the other.

I have the correct video card selected  ATI Radeon 7000 series and a Dell M781p monitor.

I need to get this system up and running very quickly.

Any help would be appreicated

Gives details of the meanings of the directives. First idea is to delete the DisplaySize entry for your monitor.

If that doesn't work, then I'd be tempted to boot into single user mode or run level 3, and:

mv /etc/X11/XF86Config /etc/X11/XF86Configbu

and then run:

While I am looking at this, have you called dell?  They officially support ES3.

No I have not contacted Dell.  I have not had good experiences with their phone support.

That command brings up the Gui to allow me t change the settings.  I can access the gui no problem.  The problem which is difficult to explain, is that when I change the resolution the output does not fit the screen, it is to big which requires me to like schroll from one side of the desktop to the other.
carric01Author Commented:
The issue has been resolved.  I installed the latest updates for the X86Free and the latest driver for the ATI Radeon.  One of those fixed the issue.  Thanks for all the responses
glad it's fixed, I was going to say you should upgrade to xorg...
