Following Launchpad bug 1513914 status being changed to Triaged; as requested I have prepared the Kernel.org format information which is listed below. Martyn Berry (new to Linux, hope this information is being sent to the correct persons) [1.] Dell E7440 touchpad jumps position. [2.] Dell E7440 touchpad works correctly when freshly started each time; but after some time running, the mouse pointer starts to randomly jump position when I try to use the touchpad. (the problem seems to only happen in a vertical direction, I have not seen the same effect in horizontal movement via touchpad control) When problem is happening, and I try to move the pointer to a new position, the pointer initially moves towards the target position OK , but as I slow down the movement in final approach to the target position, the pointer jumps quite a distance away from the target position. If I shut down Ubuntu and re-start after about 10-20 seconds, the problem is temporarily resolved. Both the USB Mouse and keyboard blue joy-button continue to work correctly while having "jumpy" touchpad problem. When I boot to Windows 7 Pro 64 bit on same PC, the touchpad always works correctly.
