The AO756 includes a multi-touch trackpad, and a "buttonless" design
such that to click the button, one must press on the sensitive surface
of the trackpad.
Regardless of the scrolling method defined in System Settings -> Mouse
and Touchpad, clicking at the bottom of the touchpad and dragging with a
different finger locks the cursor in one position, as if the touchpad is
trying to interpret a two-finger swipe. Since both fingers are not
moving, it's not interpreted as a swipe, but also isn't interpreted as
expected, as a click-and-drag event.
Additionally, the right-click and left-click functionality (along with
emulated middle-click by clicking right and left together) is not being
interpreted. The trackpad has only one switch, but should be using
finger placement on the pad to determine which click is requested.
Instead it's acting as a single-button mouse, always registering left-
click.
Additionally, the "disable trackpad while typing" functionality doesn't
appear to be working correctly, with the mouse cursor moving during
inadvertent touches to the trackpad while typing. I believe these
issues are all related, although I'll be happy to file separate bugs if
so requested.
Through testing an unrelated bug, I already know that this issue exists
in upstream kernel 3.6.2. The issue does not exist in Lucid (10.04.4
LTS live environment), which interprets right-click, left-click, and
click-and-drag functionality correctly. I didn't test two-finger
scrolling, although I have no reason to expect it doesn't work in Lucid.
In Precise, the trackpad is functional for basic use, with two-finger
scrolling working correctly, and left-click functionality working
correctly. Right-click is unavailable via control-click or alt-click,
although that may be down to a configuration option I haven't found yet.
