I installed Mint13 / MATE onto my Thinkpad T42 that has trackpoint and synaptics touchpad.
All else is fine, but the touchpad is jumpy - with smooth finger movement the pointer jumps around within about 1 cm
every now and then, and sometimes it seems to think that "button is pressed" when it's not.
