At line 350 there are touch up and down events with no motion event in-between. The evdev code actually ignores the key down events and only sends the touch down event on the first motion event. The key up events cause it to directly send the touch up event. That would therefore cause it to send a touch up event without the corresponding down event and it would get confused and stop processing further events as you saw. If that is the problem then I guess the simple solution would be to get it to track the key down events instead of just relying on the motion events. $ head -n 350 evtest.log | grep "BTN_TOUCH.*value 0" | wc -l 48</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
