I'm a bit of a newbie on here and transferred from Windows to Ubuntu on a fresh install and is currently my main OS on this laptop. The trackpad on my laptop will work fine for about the first two minutes and then gets a considerable amount of lag and stutter. I know that it's the trackpad because I've tried two separate external mice and the both work fine. I installed synaptic because I heard that that helped some people with trackpad recognition but no dice. The drivers are on there because I see a driver for the trackpad when I pull up a list of drivers in the terminal. I'm using the most current version of long running Ubuntu (16.04).
