I have a question about the touchpad in Ubuntu 13.04 on my Hp Envy 3040nr.
When I go to click tap (I don't like having to physically press the touchpad button), the cursor jerks maybe five or ten pixels in a random direction. Or, when I simply move the cursor to a location, when I release my finger from the touchpad, the cursor jumps a few pixels in a random direction.
This is a pain when I'm trying to resize windows or click small buttons especially, as a) it makes it difficult to even get on the very edge of the window to change the window size and b) even if I do, the moment I try to tap click, the cursor jumps away.
I know that in Windows, the touchpad drivers have some "forgiveness" towards very slight movement. I don't know how to emulate that on Ubuntu.
