Everything works out of the box, except for scrolling with the Nub Mouse

Configuring Xorg

create a new file in /usr/share/X11/xorg.conf.d/ named 20-thikpad.conf with the following content:

Section "InputClass"
    Identifier  "Trackpoint Wheel Emulation"
    MatchProduct    "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint|USB Trackpoint pointing device|Composite TouchPad / TrackPoint"
    MatchDevicePath "/dev/input/event*"
    Option      "EmulateWheel"      "true"
    Option      "EmulateWheelButton"    "2"
    Option      "Emulate3Buttons"   "false"
    Option      "XAxisMapping"      "6 7"
    Option      "YAxisMapping"      "4 5"
EndSection

this will enable horizontal and vertical scrolling with the Trackpoint Mouse
