Hi,

I'm using linux/xfree86 4.3 on a laptop with a docking station. I'm
using a USB mouse while docked and a PS2 mouse (the 'nipple') while
undocked. The USB mouse works fine, but the PS2 mouse just moves
randomly around the screen and often jumps to the bottom left corner and
makes X unusable.

Here's the relevant parts of my XF86Config:

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
InputDevice "PS2 Mouse"
InputDevice "USB Mouse"
InputDevice "Keyboard0"
EndSection

Section "InputDevice"
Identifier "PS2 Mouse"
Driver "mouse"
Option "CorePointer"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/psaux"
Option "Emulate3Buttons" "yes"
EndSection



Section "InputDevice"
Identifier "USB Mouse"
Driver "mouse"
Option "SendCoreEvents" "true"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "no"
EndSection

Has anyone got any pointers as to where I'm going wrong?

Thanks,

Anthony Clark
