Comment 3 for bug 441013

There are now more than a dozen bugs reported against this. See the original bug report at #378391.

The problem appears to be that as people report the bug, they are marked as dups and lniked to that bug -- but that one is marked "Fix Released". So nobody does anything to fix the bug, which is that the behavior regressed against Jaunty. (The fact that you can go into a Preferences item and restore the Jaunty behavior is nice, but the bug is that the Jaunty behavior changed. What worked in Jaunty does not work in Karmic.)

All that's needed to *really* fix this bug is to change the default preference -- so that tapping touchpads works by default, rather than only after you enable them.
