Troubleshooting

Trackpoint

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. Scrolling is still possible by holding the trackpoint's center button and pushing the trackpoint in the direction you wish to scroll.

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
