Touchpad capabilities detected incorrectly
 
Hello, I just installed Linux Mint 14 (kernel version 3.5.0-17) on a new Asus B400 ultrabook, and I am having issues with the right button on the touchpad. If I click the left button, it registers a mouse click (as expected) but when I click the right button, nothing happens.

The touchpad is detected by xinput as ETPS/2 Elantech Touchpad:
Code:

$ xinput
⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜  ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
⎜  ↳ ETPS/2 Elantech Touchpad                    id=13    [slave  pointer  (2)]

Synclient reports that the touchpad is being detected as a ClickPad, which (as I understood it) is meant for touchpads that have "virtual buttons" for left/right click. Mine has two physical, separate buttons for mouse clicks.
Code:

$ synclient -l|grep ClickPad
    ClickPad                = 1

What is more interesting is that it seems the capabilities are being reported incorrectly as well:
Code:

$ xinput list-props 13|grep Capabilities
    Synaptics Capabilities (290):    1, 0, 0, 1, 1, 1, 1

These properties show:
  • (1) device has a physical left button
  • (0) device does not have a physical middle button
  • (0) device does not have a physical right button
  • (1) device does support two-finger detection
  • (1) device does support three-finger detection
  • (1) device can configure vertical resolution
  • (1) device can configure horizontal resolution
Since the touchpad DOES have a physical right button, I think it is being detected incorrectly. I am able to right-click with the button under Windows 7, and am also able to right-click using a two-finger tap on the touchpad, but am unable to use the physical button. Any help solving this would be greatly appreciated! Thanks!

There's a potential fix on AskUbuntu: http://askubuntu.com/questions/15208...nt-right-click

You'll just need to make sure synclient shows the following:
Code:

RightButtonAreaRight=1
RightButtonAreaBottom=1
