[Bug 881830] Re: [MacBookPro8, 2] Trackpad single clicks nearly always double clicks

 

With the 3.11.0-4-generic #9-Ubuntu SMP kernel that is part of Saucy,
the errant mouse clicks are less of a problem.  They seem not to be
present any more when just using the trackpad, but still a problem when
typing.  Is a bisection still needed?  If so between which kernels?
