Since I installed Ubuntu 13.10 my mouse cursor has been disappearing every second time i boot Ubuntu 13.10. So the way I solve it is by restarting Ubuntu, and the mouse cursor will become visible again. If I would then want to make a restart again, the cursor will be gone until a restart has been done. So to sum up - every second boot will show a cursor, and the other will not.

Now of course I can keep on doing like this, but it is VERY annoying. So i would ask if there was a way of solving this. Please do not hesitate to ask me for more information about my system if needed.
