** Description changed: - Using an Apple Magic Trackpad in Unity... + Update: The cause has been traced down to either a kernel or hardware + issue as per comment #4. - Touch 3 fingers: After a second or two (?!) the grab handles appear but - the trackpad goes dead. Only my mouse continues to work. The trackpad - comes back to life a while after the grab handles vanish, and I've moved - the pointer with the mouse. + TEST CASE: - Touch 4 fingers: Trackpad goes dead again. Takes a while before it - starts responding again. This also triggers bug 859069. + Test case without X or Unity: + 1. Pair the trackpad using hcitool/hidd utilities. + 2. Run: evtest /dev/input/whatever + You will see lots of input events for 1 or 2 finger touches. However the evtest event stream freezes when 3 or more fingers are touched. + + Test case in Unity: + + Touch 3 fingers: After a second or two (?!) the grab handles appear but the trackpad goes dead. Only my mouse continues to work. The trackpad comes back to life a while after the grab handles vanish, and I've moved the pointer with the mouse. + Touch 4 fingers: Trackpad goes dead again.
