Public bug reported: After starting the laptop the touchpad works for about 20-30 seconds after login. Am only able to utilize external USB mouse for functional control over the pointer. This is a fresh install (not upgrade) to the new LTS 16.04, Touchpad was working correctly with the last LTS 14.04. Unloading and reloading the mouse does nothing.
