<pre>What was the actual value the trackpoint range tool gave you? And did you
verify that the range was set on the udev device correctly? The hwdb is a bit
fickle.
the max delta is currently at 60 as you noted, so the delta returned from the
accel code is (60, 60) maximum. it's not directional, so a diagonal max delta
is a longer vector than a horizontal/vertical, but meh.
Given the average trackpoint with ~80Hz this means at full pressure you'd get
60 * 80 pixels per second = 4800 pixels. That's the limit, but that should in
your setup allow for a full movement from left to right within a second. The
timestamps in your log suggest that the average report rate is around ~10ms, so
this isn't an issue with the trackpoint not reporting fast enough.
I have a 3840x1200 setup here and with the right range configured (30 here), I
can verify the above and cross from left to right within approx 1 second.
That's a far cry off the 5 seconds you mentioned in the first post.
So what's going on here?</pre>
