Gursimran:

1. If scroll is invoked with one finger, increase the value of EmulateTwoFingerMinW. Yours is 3, which is very small. A value of 5 works well for me, but your number may vary, depending on your touchpad and your fingers.

2. It's not a fix, it's a workaround. A fix would involve a patch to gnome-mouse-properties.

3. This bug is not about multitouch, but about two-finger scroll. Since my workaround allows two-finger scroll, I think it's a valid workaround. There is another bug for multitouch. If a person wants two-finger scroll, what difference does it make if he gets it through multitouch emulation or through real multitouch? I don't understand your complaint.

4. Pinch/zoom via multitouch are features that depend on application support as well, and to the best of my knowledge no applications support for Ubuntu support these gestures, so this is more than a driver issue.
