[SOLVED] Synaptics touchpad does not work

I have an Acer Aspire V5-121, and it uses a Synaptics touchpad. Preferring a mouse to the touchpad, I never even noticed that the touchpad did not work until today.

The touchpad does not respond. First I thought it had been disabled because of detection of an external mouse. However even removing the external mouse did not re-enable the touchpad.

Reading somewhere about this, I created a dir /etc/X11/xorg.conf.d and created a file /etc/X11/xorg.conf.d/synaptics.conf, with the following content:

Section "InputClass"
        Identifier      "Touchpad"                      # required
        MatchIsTouchpad "yes"                           # required
        Driver          "synaptics"                     # required
        Option          "MinSpeed"              "0.5"
        Option          "MaxSpeed"              "1.0"
        Option          "AccelFactor"           "0.075"
        Option          "TapButton1"            "1"
        Option          "TapButton2"            "2"     # multitouch
        Option          "TapButton3"            "3"     # multitouch
        Option          "VertTwoFingerScroll"   "1"     # multitouch
        Option          "HorizTwoFingerScroll"  "1"     # multitouch
        Option          "VertEdgeScroll"        "1"
        Option          "CoastingSpeed"         "8"
        Option          "CornerCoasting"        "1"
        Option          "CircularScrolling"     "1"
        Option          "CircScrollTrigger"     "7"
        Option          "EdgeMotionUseAlways"   "1"
        Option          "LBCornerButton"        "8"     # browser "back" btn
        Option          "RBCornerButton"        "9"     # browser "forward" btn
EndSection

That didnt help.
What's the proper method to go about finding out what's wrong?

I'm on CrunchBang 11 waldorf

Apparently the touchpad has been detected?

I also installed gpointing-device-settings. On opening it I found that the option to disable touchpad, had not been enabled.

Re: [SOLVED] Synaptics touchpad does not work

I read the arch wiki, and though I found a lot of information, and potential solutions, none of them worked.
