Bug Description
I recently installed Ubuntu 11.04 on a Lenovo T410s and noticed that the mouse cursor/pointer would jump/reset periodically. If I had Twinview on the pointer would reset somewhere on the other monitor. I turned that off and the pointer still reset but within the only existing screen available. I disabled all the mouse input devices and enabled them one at a time starting with my USB mouse until I found the one that caused the resets.
I was able to temporarily fix the problem by disabling the "N-Trig Pen eraser" input device.
