If you don't get the BTN_LEFT event (like in the sequence I pointed out) then the hw is still considering itself down. Especially on the T440 it's hard to hold the touchpad down without a finger down, given how it's designed (though there are narrow dead areas on the edges). > the click is occasionally arriving before the touch? yeah, but that doesn't matter to us. In your case the problem is that the BTN_LEFT value 0 does not arrive at all when the finger is released, see the 1.950450 event. regarding the pen, let me re-explain: when the button is logically stuck and you are not touching the touchpad, that's when I need you to click again with the pen and check whether this triggers a sole BTN_LEFT 0 event. Because if so, then it's the switch. If not, then we have some other issues with the firmware most likely.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
