Can I remove the mouse pointer entirely from X? As in removing it and not just hiding it?
I don't use the mouse at all. Everything I do is completely keyboard driven, so I hide the mouse pointer and disable my touchpad. However, the cursor still has a position on my screen, which causes applications to fire hover events.
This can be extremely annoying, for instance in chrome, if a link happens to intersect the cursor it will display a bright white tooltip in the bottom left of the window.
