Mouse jumps between using touchscreen and touchpad [closed]

Am I wrong if I guess at the moment of time you were referring at the second paragraph:

At first I thought it might be remembering the mouse position for each device separately [...]

You were using Unity but then you changed to Gnome and thus changed your mind about the behaviour?

I also own a touchscreen laptop and I'm running Ubuntu 12.10 x64. Using Unity I can leave the mouse in a specific point, let's call it point A, then tap or drag on the screen in a completely different and random point in the screen and no matter what when I move my mouse (or trackpad) the pointer will begin it's movement from A.

However while using Gnome (3.6.2) the behaviour gets buggy. If I leave the pointer at A using the mouse/touchpad, then tap/drag in the screen to a final point B and then get to the mouse again the pointer will most of the times jump from B to a lower-right position as you described and in some cases it will start from A as in Unity.

I heard Canonical updated the touchscreen drivers in Ubuntu 12.10 and I guess they updated their desktop environment to suit these updates too. For me when I want to use the touchcreen I load Unity as in Gnome is mostly useless.

Cheers.
