In my case, when I installed this S-7.3, I chose to have three resolutions: 1024x768, 800x600 and 640x480. YaST2, in its infinite wisdom, decided that 1027x768 should be the default resolution, so the image fits perfectly the display, but the other two do exactly what you describe: I have to use the mouse to move the image one way or the other (or both, vertically and horizonatlly) if I want to see the whole image. I'd love to have the 800x600 and 640x480 filling the display just as well as 1024x768, but I don't know how. Maybe it's not techinically possible.
IMHO it's not possible with XFree86. As you have found out: Virtual screen resolution cannot be changed without restarting the X-server and is set, by default, to fit all configured video modes. But if I understand it right, this is not related to the original problem. -- Alexandr.Malusek@imv.liu.se
