On my Pentium II PC knoppix will start up well, but the video screen is devided into two halfs. The right part of the desktop seems to be on the left of the screen and the left part on the right. So the right border and the left border of the screen meet in the middle. Verry strange. However, clicking on items on the screen needs to be done on the places they should be. So I see the start menu of KDE in the middle (bottom), but to open it I have to click on the place it normally is, left bottom. Can someone help me with this.
