The touch-pad on the Thinkpad S540 is extremely erratic (the cursor often jumps when right-clicking, making it extremely difficult to right click anything, and even left-click sensitivity seems to be very poor). I am using Ubuntu 12.04.3 LTS
. The touchpad is an "all in one" variety with no separate left and right buttons, but having them built in to the pad area.
Is there anywhere I can obtain better touchpad drivers? or generally anything else I can do to improve the mouse behavior?
