Clicking on Apple Macbook Pro trackpads under Ubuntu Precise

Apple trackpads don't have separate buttons, the entire trackpad is itself a clickable button. The default OS X behaviour is to treat clicking the pad with two fingers as the right button, and clicking the pad with three fingers as the middle button. Enabling tap to click (i.e. touching the trackpad but not actually clicking it) tends to result in false positives since the trackpad is so big. I therefore setup this behaviour under Ubuntu Oneiric.

When I upgraded to Ubuntu Precise two finger clicks started registering as the left button. (Three finger clicks still worked.) It turns out that this is due to the new clickpad support in Precise. The solution is to disable the ClickPad attribute. My Synaptics configuration now looks like this:

TapButton1              = 0
TapButton2              = 0
TapButton3              = 0
ClickFinger1            = 1
ClickFinger2            = 3
ClickFinger3            = 2
ClickPad                = 0
