Comment 9 for bug 1046512

Thanks. I've put the test build at the link below. Please install, then install the input-utils package and reboot into the debug kernel.

After rebooting, try to avoid touching the touchpad. Use Ctrl-Alt-F1 to switch to a virtual console and log in. Run 'sudo lsinput' and identify the touchpad device in the ouput, making note of the number of the associated input device (e.g. if the device is /dev/input/event0 then the device number is 0). Then run 'sudo input-events devnr > input-events-lr.txt', where devnr is the device number from lsinput. Drag your finger slowly across the touchpad from the extreme left to the extreme right, keeping the virtical position of your finger roughly near the center of the touchpad, then press Ctrl-C. Next run 'sudo input-events devnr > input-events-tb.txt' and drag your finger from the extreme top to the extreme bottom with the horizontal position roughly in the center, then press Ctrl-C. Then run 'dmesg > dmesg.txt'.

After that you can switch back to the desktop by pressing Ctrl-Alt-F7. Please attach intput-events-lr.txt, input-events-tb.txt and dmesg.txt to this bug. Thanks!
