Hi, I split up my previous topic as requested. The problem I face is that the acceleration profile I experience is always flat no matter what the speed is set to. That is to say, the acceleration it's kind of fixed to a value which depends on the speed setting. It looks like the mouse cursor movement is just a 'zoomed' version of the touchpad movement, with a 'zooming factor' determined by the above mentioned speed property.

can you try the patch in bug 93503? I noticed the movement is a bit jerky, I wonder if that's the screencast or the device. If the patch has no effect, please also attach two evemu recordings, one slow, one fast one.
closing after 6 months of silence, please reopen if required
