The default configuration of the xf86-input-synaptics driver makes the clickpad almost unusable (on the T440s). Clicks/Taps do not register properly, misclicking, no palm detection, no soft buttons where they should be, and so on... The following configuration can be put in /etc/X11/xorg.conf.d/99-synaptics.conf As a result the clickpad will react a lot more 'calm' than before and the middle & right click button areas match with the printed ones on top of the clickpad.
