<pre>I'm wondering if <a class="bz_bug_link
bz_status_NEW "
title="NEW - Kernel absfuzz handling is inconsistent"
href="show_bug.cgi?id=105303">bug 105303</a> has something to do with that, although that
wouldn't trigger a delta of 13. Still, might be worth trying this script:
#!/bin/bash
fuzz=0
device=/dev/input/event4
sudo libevdev-tweak-device --abs ABS_X --fuzz $fuzz $device
sudo libevdev-tweak-device --abs ABS_Y --fuzz $fuzz $device
sudo libevdev-tweak-device --abs ABS_MT_POSITION_X --fuzz $fuzz $device
sudo libevdev-tweak-device --abs ABS_MT_POSITION_Y --fuzz $fuzz $device
Run that against the touchpad device (i.e. replace the device node accordingly)
and restart X. This may cause some pointer wobble, the question is whether it
reduces the jumps.</pre>
