Hi all,

For what it's worth, there are multiple different configuration 
approaches, and you may have different results with:
    udev rules
    whatever your desktop environment does with its mouse speed.

(the serioX  depends on platform).

For most thinkpads (including all the X1 Carbons of the last 5 years), 
the magic incantation is to put this into 

KERNEL=="serio2", SUBSYSTEM=="serio", DRIVERS=="psmouse", 
ATTR{sensitivity}:="255", ATTR{speed}:="255"

Trackpoint drift most often occurs when you rest your finger on it when 
idle, and it is constantly recalibrating for it's own "DC level". The 
trick is to practice not doing that.
