Options: --absolute Use absolute position
Example: to move the cursor to absolute coordinates (100,100):
ydotool mousemove --absolute 100 100
This is already implemented, see the mouseto action. The X and Y are percentages, so for the center of the screen you'd use:
echo mouseto 0.5 0.5 | dotooliirc ydotool just whips a relative pointer device into a corner before trying to position it (which gets it extra wrong if there's mouse acceleration) and hence has pretty arbitrary units.
