Hiding the mouse cursor when I use my touchscreen?

[Tommy]

This is a very minor bug, but as I was testing out 13.04 (Raring Ringtail) on my Acer Aspire V5 (which has a 15.6 inch touch screen), I noticed that the mouse arrow doesn't disappear even though I'm using the touchscreen as an input device.

What should happen is when I touch the screen, the mouse arrow should disappear and stay invisible. Then when I touch my trackpad again, that should make the mouse arrow visible again. This would also help Ubuntu look more polished on tablet devices, or hybrids, like the Lenovo Yoga or the Thinkpad Twist.

Any update?

Actually it's already implemented in recent versions of Ubuntu. Would have been nice to know how it was implemented.
