This should be a joke.
I recently have bought a graphical tablet and I have experimented an stupid problem after to connect it in the PC.
The first time I saw a new pointer into the screen only for the tablet, I had no problem with that because I could maintain two pointers for each task. The problem happened when I reconnect it after clean it: a new pointer into the screen, the old one did not disappear after disconnect the tablet.
I have login in using GNOME option on display manager.
