Comment 0 for bug 1094451

I have two identical spec NP900X4C laptops. On one I installed 12.10, on the other 12.04.

On 12.10 the touchpad works fine, including right-click.

On 12.04 the touchpad works fine, EXCEPT for right-click. The standard settings options do not correct this problem.

I tried following the Enabling right button click instructions at https://wiki.ubuntu.com/DebuggingTouchpadDetection however the enable-rightbutton.sh script bailed out claiming the right-click area was not defined. The issue is also simpler than the mixture of problems reported at https://bugs.launchpad.net/bugs/933707

I therefore used xinput list-props on both devices to compare the settings for the touchpad. I discovered that on 12.04 "Synaptics Soft Button Areas" is set to all 0s, whereas on 12.10 it has specific settings.

I therefore applied the following command and the right-button immediately worked fine. I opened this bug so that the correct setting for this model of touchpad can be included in the standard 12.04 package.
 xinput set-prop <device-id> <property-id> 1630, 0, 1871, 0, 0, 0, 0,0
