-From: Chase Douglas <chase.doug...@canonical.com>
-Date: Wed, 30 Mar 2011 10:47:13 -0400
-Subject: [PATCH] Revert "Default to 2-finger emulation when HW supports it"
-
-The default pressure threshold set by this patch is low enough to cause
-spurious behavior in some devices. One bug report also notes that the
-pressure values seem to vary with environment state (temperature,
-air pressure, etc.). Thus, this commit is being reverted to restore
-behavior to what it was before Natty.
-
-This reverts upstream commit ffa6dc2809734a6aaa690e9133d6761480603a68.
-
-Fixes LP: #742213
