Bug Description
Binary package hint: xserver-
On slow movement the touchpad/mouse does not move or stutters coarsely.
Definition of slow movement: The fingertip does not move due to stiction and then suddenly starts moving. This stopping and moving is continued by the user. The fingertip is "stuttering" across the touchpad.
Example: The user tries to position the mouse exactly and therefore moves his fingertip very slow. It's very hard to position the mouse because nothing is happening in the first instance. After a while and some distance on the touchpad without effect the mouse jumps for half an inch or so.
If the mouse is moving fast and smoothly everything is alright.
This behaviour appears in version 0.99.3-2ubuntu5 only. In version 0.99.3-2ubuntu4 every movement is somehow interpreted an it is possible to position the mouse exactly by slow movement.
Therefore i suppose it's got something to do with this bug-fix:
* debian/
- Prevent the cursor from jumping when movement
events are lost or when they take place in
such a little time that no human hand could
ever trigger them (LP: #365943).
I hope somebody is looking though this description. :)
