Description Christopher James Halse Rogers 2012-04-25 15:44:00 UTC

The MacBook hardware seems to trigger some input on the touchpad on lid close, before the suspend process has kicked in.  This leaves the driver in an inconsistent state on resume, causing funky touchpad behaviour.

http://patchwork.freedesktop.org/patch/10055/ seems to mostly fix this, but apparently there's still some problem.  Testers on the Launchpad bug report that the touchpad treats single-clicks as double-clicks after 3 of 20 resumes.
