** Description changed: Ubuntu 14.04 on ThinkPad T440s in clamshell mode using external monitor: The mouse periodically (not always) starts lagging dramatically. It's difficult to position it when this happens, as I'll move the mouse and the pointer will react a later, sometimes a long as a second, and with little precision. Virtually unusable when it gets this way. I've checked system monitor for runaway processes, and nothing is hogging the CPU. - The mouse is a Microsoft wireless (optical). This also occurred with a - Logitech wireless mouse. + The mouse is a Microsoft wireless (optical).
