Synaptics Touchpad

A much enhanced driver for this versatile touchpad can be downloaded from http://tuxmobil.org/. It provides support for many interesting features of the touchpad. To use the driver the following needs to be added to /etc/X11/xorg.conf:

Section "InputDevice"
	Driver        "Synaptics Mouse"
	Identifier    "Touchpad"
	Option	      "CorePointer"
	Option        "Device"        "/dev/psaux"
	Option        "Protocol"      "auto-dev"
	Option        "LeftEdge"      "1700"
	Option        "RightEdge"     "5300"
	Option        "TopEdge"       "1700"
	Option        "BottomEdge"    "4200"
	Option        "FingerLow"     "25"
	Option        "FingerHigh"    "30"
	Option        "MaxTapTime"    "180"
	Option        "MaxTapMove"    "220"
	Option        "VertScrollDelta" "100"
	Option        "MinSpeed"      "0.06"
	Option        "MaxSpeed"      "0.12"
	Option        "AccelFactor"   "0.0010"
	Option        "SHMConfig"     "on"
	#Option       "Repeater"      "/dev/ps2mouse"
EndSection

Also, the ServerLayout-section needs some changes:

Section "ServerLayout"
	Identifier     "XFree86 Configured"
	Screen      0  "Screen0" 0 0
	InputDevice    "Keyboard0" "CoreKeyboard"
	InputDevice    "Touchpad" "CorePointer"
	InputDevice    "Mouse0" "AlwaysCore"
EndSection

Note you can have only one CorePointer at a time, the other devices need to be specified as AlwaysCore instead.

IMPORTANT: This driver requires kernel support for the psaux and evdev devices. These are normally enabled in the kernel. If not, requires kernel rebuild.
