How to enable touchpad scrolling and tapping in Debian Wheezy KDE?

EDIT: I just got tapping working on my Debian AlpsPS/2 touichpad with synclient:

synclient TapButton1=1

---

I am not an expert on this but found an old synaptics.conf file that I was using on a different laptop:

Section "InputClass"
    Identifier      "touchpad catchall"
    MatchIsTouchpad "on"
    MatchDevicePath "/dev/input/event*"
    Option          "HorizEdgeScroll"    "1"
    Option          "MaxTapTime"        "300"
    Driver          "synaptics"
EndSection

So, try adding catchall to the Identifier and changing MatchIsTouchpad to on from yes. Not sure if that will help but should be worth a try.

Another thing you can try is installing tpconfig:

sudo apt-get install tpconfig 

That should give you a GUI to enable taps with:

 sudo tpconfig --tapmode=1

_{Though I just tried this on my system and it does not seem to work}

Have you tried synaptiks? It's a simple GUI program that always solved any problems with my touchpad configuration.

To install:

sudo apt-get install kde-config-touchpad

Then you should be able to run it with

synaptiks && synaptiks

(the first synaptiks only puts the icon in the system tray and doesn't launch the GUI for some reason)
