i tried using knoppix on the said laptop and at first, everything went well, but as soon as the GUI interface starts, my mouse cursor just stays in the middle and when i try to move the cursor using the finger pad, it won't move at all. I also tried to reboot it and connected a ps/2 mouse, but then again, the same problem occurs: the finger pad does not work as well as the ps/2 mouse...

what can i do?
