Synaptics Touchpad and a ps/2 mouse together

I'm running Suse 8.2 Professional on a Dell Latitude CPI-R

I'm having trouble getting both the Synaptics Touchpad and a ps/2 mouse working together.

I have both configured and the Synaptics pad works perfectly. However, when I plug in a ps/2 mouse (with the power off) and boot the machine, it hangs just before it gets to the login screen.

Is there a way I can have it so that if there is no mouse plugged in, the pad works, but if I plug in a ps/2 mouse, that works instead?

Here's how I have the bits of my XF86Config file:

Code:

Section "Module"

  Load        "v4l"

  Load        "freetype"

  Load        "speedo"

  Load        "type1"

  Load        "extmod"

  Load        "dbe"

  Load        "glx"

  Load        "synaptics"

EndSection



Section "InputDevice"

  Driver      "mouse"

  Identifier  "Mouse[1]"

  Option      "ButtonNumber" "5"

  Option      "Device" "/dev/mouse"

  Option      "Name" "Autodetection"

  Option      "Protocol" "imps/2"

  Option      "Vendor" "Sysp"

  Option      "ZAxisMapping" "4 5"

EndSection



Section "InputDevice"

  Driver          "synaptics"

  Identifier          "Mouse[3]"

  Option        "Device" "/dev/psaux"

  Option        "Edges" "1900 5400 1800 3900"

  Option        "Finger" "25 30"

  Option        "MaxTapTime" "0"

  Option        "MaxTapMove" "220"

  Option        "VertScrollDelta" "100"

  Option        "MinSpeed" "0.02"

  Option        "MaxSpeed" "0.18"

  Option        "AccelFactor" "0.0010"

#  Option        "Repeater" "/dev/ps2mouse"

#  Option        "SHMConfig" "on"

EndSection



Section "ServerLayout"

  Identifier  "Layout[all]"

  InputDevice  "Keyboard[0]" "CoreKeyboard"

  InputDevice  "Mouse[1]" "CorePointer"

  InputDevice  "Mouse[3]" "SendCoreEvents"



  Screen      "Screen[0]"

EndSection

I apologise if this has been asked thousands of times. I did look before I posted.

regards

i read up on the suse support database and it told me to change my XF86Config to:

Code:

Section "InputDevice"

  Driver          "synaptics"

  Identifier          "Mouse[1]"

  Option        "Device" "/dev/psaux"

  Option        "Edges" "1900 5400 1800 3900"

  Option        "Finger" "25 30"

  Option        "MaxTapTime" "0"

  Option        "MaxTapMove" "220"

  Option        "VertScrollDelta" "100"

  Option        "MinSpeed" "0.02"

  Option        "MaxSpeed" "0.18"

  Option        "AccelFactor" "0.0010"

#  Option        "Repeater" "/dev/ps2mouse"

#  Option        "SHMConfig" "on"

EndSection



Section "InputDevice"

  Driver      "mouse"

  Identifier  "Mouse[1]"

  Option      "ButtonNumber" "5"

  Option      "Device" "/dev/mouse"

  Option      "Name" "Autodetection"

  Option      "Protocol" "imps/2"

  Option      "Vendor" "Sysp"

  Option      "ZAxisMapping" "4 5"

EndSection

but that didn't work either. i know it's something to do with them both being "/dev/psaux" i've tried changing the "imps/2" to "ps/2" with the mouse but then i lose my mouse wheel.

do i have to sacrifice my mouse wheel to get this to work?

I don't know the difference between "ps/2" and "imps/2" . Is that mean imps/2 only support Usb mouse and ps/2 support both types?
the wheel doesn't work might because of the buttonNumber.
i don't know the use of the 2 note line.
if the Synaptics Touchpad could use I wonder if someone could tell me how to fix IBM trackpoint under linux
