no multitouch gestures?

I can reproduce this here, on a Synaptics MT touchpad. It supported 3 finger tap to move windows up till now.

One probable reason for the change could be that 3 finger tap will now be reassigned to open the HUD (already mentioned in design spec)

I can confirm this bug on my Magic Trackpad. Three-finger gestures also seem to be affected on the touchpad of my laptop.

I have the same problem on my Dell Inspiron N5010. Three finger drag (to move window) and tap (to show resize/move handles) used to work in 11.10, but doesn't in precise. (Both 11.10 and 12.04 were installed as a clean fresh install)

I can confirm this on my Lenovo Thinkpad Edge E525. Multitouch isn't working.

I have a MacBook Pro 8.2. Gestures work just fine with the integrated Touchpad. I have a new Bluetooth-connected Magic TrackPad. Two-finger scrolling works, but the other multitouch gestures do not.

Not sure if this would help or not. The Xorg.0.log on my MacBook Pro 8.2 has these entries for both TrackPads:

These are the entries in my Xorg.0.log corresponding to the internal TrackPad (Which works great):

I don't know if this will help anyone else, but I just discovered that gestures on my Bluetooth Trackpad work fine if I log out/in. I also noticed that everything works if the Trackpad is turned on before LightDM starts up.

Same here on Acer notebook, SynPS/2 Synaptics Touchpad. Two finger scroll works fine, anything else produces no response, the mouse doesn't even move, meaning that it's registering multiple touch points and doing nothing.
