How to remove touchpad lag?
The touchpad on my new laptop works fine (with multitouch and all) but when I stop moving my finger the mouse pointer still moves for a quarter of a second or similar as if a low-pass would filter the movements.
I know that when using the OS from M$ you can actually activate and deactivate this filter that makes me always miss the button I want to click on.
Is there a way to do the same on Ubuntu?

Arrgh! Didn't see the notification mail. Hope you're still on the case, though: Normally if I fail to find a helping answer - you most certainly will.

Thanks a lot!
Created Bug #1305494. Did hope I somehow missed a configuration option. You never know...
