A cheap mouse allows finer and faster control than the best touchpad that currently exists, so... I plug in a mouse. (Don't believe me? Play an FPS game with touchpad against a mouse user.)
That said, Synaptics touchpad support on Linux is bad. In my case, it's the touchpad on a Thinkpad T440s. It can run in a legacy/standard protocol mode or a "modern" protocol mode. Linux supposedly supports the latter (where palm detection should work) since a few years, but I don't see it being used or palm detection working.
