yeah, that's a built-in trackpoint feature that we don't have control over. > > As for the drifting, is this something on your device only or a general > > issue affecting this class of devices?

Is there a guide? judging by the output in the .txt file, you didn't run the cd command correctly and ended up in some other device's directory. I'm honestly not sure if there's a guide or even documentation but you can find bits and pieces with google. drift_time is probably the key here, maybe resetafter or resync_time.
