Is this piece of information relevent to my problem? https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X250#Mouse
Mouse The touchpad and TrackPoint work out of the box, but the physical buttons for the trackpoint do not. You will need to install xf86-input-synaptics. Note: The most recent Linux kernels (at least 4.0.5) support TrackPoint buttons out of the box. The following information pertains only to older versions of the kernel. If you would rather not install a recent kernel, there is a work around for Linux 3.19.2-ARCH. If you add options psmouse proto=imps to /etc/modprobe.d/x250.conf, you can force the mouse module to use a more basic protocol than the built in one for the TrackPoint, which needs a patch. The effect is that the touchpad and mouse are treated as one device, but synaptics is not supported. If you want two finger scrolling, for example, you will need to either deal with the broken TrackPoint buttons are install the new module.
