There are some issues regarding the trackpoint on the ThinkPad L530 and L430 series. See https://bugzilla.kernel.org/show_bug.cgi?id=33292

Warning: This is just a quick and dirty workaround. The following solution will remove the two-finger-scroll functionality of the touchpad

Load the kernelmodule psmouse with the options proto=bare:

# echo "options psmouse proto=bare" | sudo tee /etc/modprobe.d/trackpoint-elantech.conf 

Reload the kernelmodule, the trackpoint should now be usable:

# sudo modprobe -rv psmouse && sudo modprobe -v psmouse
