I have a Sony Vaio SZ640. I used to run Fedora 8 and the touchpad worked fine. However, when I switched to Ubuntu 8.04, my touchpad responds to any action by instantly placing the mouse in the bottom left corner of the screen (click or drag). I have a temporary USB mouse which is working fine, but I would like to get the touchpad to work. Has anyone had the same issue? Please let me know if you need additional information (xorg.conf or anything else). Thanks
