Synaptics touchpad with X.Org

The default X-Window server in Debian GNU/Linux Testing (Etch) is now X.Org. The XFree86 was abandoned due a license change (what a stupid change!).

To enable tap and drag actions on the touchpad, install the xfree86-driver-synaptics package, and configure the relevant section in /etc/X11/xorg.conf as follow:

Section "InputDevice"
        Identifier      "Configured Mouse"
        # Driver        "mouse"
        Driver          "synaptics"
        Option          "CorePointer"
        Option          "Device"                "/dev/gpmdata"
        # Option        "Protocol"              "IntelliMouse"
        Option          "Protocol"              "auto-dev"
        Option          "Emulate3Buttons"       "true"
        Option          "ZAxisMapping"          "4 5"
        # Option        "MaxTapTime"            "0"
EndSection
