You have been subscribed to a public bug: I'm running Ubuntu Desktop 12.04 64bit on an HP Elitebook 2760p. This occurs under Unity and gnome-shell, and I imagine any other DE. I am not sure what software provides the functionality I am discussing below, so please assign the bug accordingly.
What is expected: When I use my finger tips to interact with the system, I expect the cursor to move to where my touch was registered. If I tap, I expect a "click" to be sent at the location where I tapped. If I tap and drag, I expect the cursor to follow my input. What happens instead: The cursor does not first move to where the tap was registered. When I tap, a "click" is sent to whatever happens to be below where the cursor is currently positioned. Tap and drag, again, starts from the location where the cursor was previously located, and uses a strange acceleration (the mouse cursor moves further away the faster I drag). In clearer terms, the touchscreen is behaving less like a tablet and more like a big, dumb trackpad. Despite these issues, the system's included stylus still functions exactly as expected. This was working as expected earlier in beta, and changed sometime after mid-February, when I originally installed Ubuntu from a then-current daily ISO. I had not used the installation for some time and recently discovered the issue. I had other issues with that installation, so I thought it wouldbe best to reinstall from today's daily ISO and ran 'aptitude full-upgrade'. The issue persists. Therefore, I believe this is a regression, and not something specific to my machine.
