physical screen size, virtual screen size, make it 1:1

Hello! Short time ago I installed KDE from SuSE 8.1. After that I recognized that the screen scrolls if I reach the rightmost respectively the upmost position on the screen with the mouse pointer. I do not like that. How KDE can be configuered that the whole KDE screen content is shown on the whole physical screen (Display) without scrolling? I used only fvwm2 and was not faced to this situation before. Any help appreciated. (Resolution 1024 x 768 on 17" CRT Display) -- Rgds. _ # Michael # _
