Comment 3 for bug 581659

Hi bug reporter.
First of all Thanks to report the bug and help us to make ubuntu better.

I think your bug is quite confirmed as I and possibly all can reproduce the cursor jump. Although I'm sure that this is infact a bug or not as this probably is in the developers knowledge.Like for example when you enable the circular scroll feature of gsynaptics you have to scroll all through the boundary while the native drivers for synaptics in windows you can make small circles anywhere. So that seems to a limitation rather than a bug. So it could be added in a wishlist rather that filing a bug

Still meanwhile I confirm that it is really a bug you could possibly help developers by including the outputs of following programs

One thing that will help developers to identify the problem is the xev program that capture the input events that the xserver receives.
You can run `xev -geometry 900x100-0+120 > ~/xev.txt`. That will give you a 900 px wide and 100 pixel high window at the right hand side of the screen and events are captured as long as the mouse pointer is inside the window. Close the window with Alt+F4 (in order to not generate more mouse pointer moving events). Take care to not drag the mouse pointer over the window any more than necessary during this, since it will create noise in the log. Upload xev.txt here.
Increase the pixels of the window so the jump is included in the log output and the cursor remains inside the window after the jump. Further try to demonstrate all other issues that you reported in the output.

Second use should also preferably use synclient to get such debugging output files. Use man synclient to use this program. If you are not able to use it report back, I or somebody will help you preferably...

Regards
