Synaptics Touchpad, left mouse button fails to register

About 2 - 3 days ago, the synaptics driver, kernel & udev was updated and all of a sudden my left mouse button on the touchpad is not registering (ie. if I click with it, nothing happens, not even if I try multiple times). I turned off the touchpad (has a button to do that), plugged in an old USB mouse and rebooted (Was in the middle of work, didn't want to sort it out then).

However the problem still persists. After further investigation, I came to the follow observations:

1. If the touchpad is active on boot, then neither the left mouse click on the touchpad or the USB mouse is registered. Even then turning it off, does not allow the left click button to work on the USB mouse.

2. If the touchpad is not active on boot, then the the mouse works well, however if I enable the touchpad afterwards the left click button does not work on the mouse again.

To summarize, if the onboard touchpad on button is active (ie. the laptop on/off button for the touchpad), my left clicks do not register, regardless of which mouse/touchpad I use.

The laptop I have is a HP Pavilion dv6-2140ed.

Package versions (x86_64) I have are as follows:

• linux 3.2.11-1

• linux-api-headers 3.1.6-1

• linux-firmware 20120227-1

• udev 181-5

• xf86-input-evdev 2.7.0-2

• xf86-input-mouse 1.7.2-1

• xf86-input-synaptics 1.5.99.901-2

• xorg-server 1.12.0-1

• xorg-server-common 1.12.0-1

• xorg-xinput 1.5.99.1-1

My synaptics configuration (/etc/X11/xorg.conf.d/10-synaptics.conf) is as follows:

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "1"
        Option "TapButton2" "2"
        Option "TapButton3" "3"
EndSection

Installed xorg-xinput, and did xinput -list, which gave me the following:

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Logitech USB-PS/2 Optical Mouse         	id=10	[slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad              	id=13	[slave  pointer  (2)]
⎜   ↳ MCE IR Keyboard/Mouse (ene_ir)          	id=15	[slave  pointer  (2)]

The command xinput list-props "SynPS/2 Synaptics TouchPad" | grep Capabilities gives:

Synaptics Capabilities (300):	1, 0, 1, 0, 0, 1, 1

Also command cat /proc/bus/input/devices gives:

I: Bus=0011 Vendor=0002 Product=0007 Version=01b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0

H: Handlers=mouse1 event11 
B: PROP=1
B: EV=b
B: KEY=420 30000 0 0 0 0
B: ABS=11000003

A quick look at Xorg.0.log does not indicate any errors or problems.

It seems like it is all configured right. Also it is only the actual left click button which fails to register (right click works, scrolling, moving mouse, etc), leaving me to believe it is a bug, not a configuration mistake. I believe it is related to the actual laptop touchpad on/off button. A quick search of the forums and google does not reveal any similar posts.

I was wondering if anyone any ideas, suggestions or any other information related to this bug/problem.
