Adjust trackpoint drift
When the trackpoint does not move for 0.5 seconds, it re-calibrates that point as zero. Hence, if you hold the trackpoint in the same place for more than 0.5 seconds (for instance while scrolling), the trackpoint re-calibrates that position as zero. When you leave the trackpoint, it re-calibrates again, leading to the infamous trackpoint drift.
On Linux, this value can be changed from 0.5 seconds to anything you like. For instance, to set it to 2.5 seconds:
# echo 25 >/sys/devices/platform/i8042/serio1/serio2/drift_time
