Why does my mouse cursor drift?
by hazel from LinuxQuestions.org on (#6MRJQ)
I have noticed a tendency of my mouse cursor to gradually drift downwards, often to the point where a movement intended to scroll down text ends up on the panel and takes me to another desktop. It may be of course that I have an unconscious tendency to pull on the mouse, but I have noticed a certain amount of drift even when I am not holding the thing. What causes this?
