2011-10-06 03:58:06 Daniel van Vugt description Using an Apple Magic Trackpad 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. Takes a while before it starts responding again. This also triggers bug 859069. I can reproduce the above bugs in Ubuntu 11.04 and 11.10 beta 2 (live).

TEST CASE: 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.
