Yes; i don't think I bumped into the pad or anything either with the heel of my thumb/palm. I tried to keep as far away from it as I could when starting. I can always generate another one via SSH and then try to reproduce while that's running so I can be sure I had no physical contact with the machine when starting, but it's fairly sporadic (though often) and a little bit difficult to reproduce intentionally. > All other BTN_TOOL_FINGER events point at a potential hardware issue, > whenever the device switches to single-finger down (FINGER is 1) it > immediately switches to two fingers in the subsequent event (DOUBLETAP is > 1).

Hrm.. the hardware's fairly new (laptop was purchased/unboxed about two? three? weeks ago). That doesn't of course rule out faulty manufacturing but it does certainly make it being a hardware-level issue less likely, I'd presume. Anything I can try to help narrow it down?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
