USBmouse/touchpad together, touchpad behaves erratically


I recently switched from Redhat9 and Mandrake 9.2 on my laptop and I am very happy with it with an exception. Initially my major concern was trying to get my touchpad and USB mouse working simultaneously as was the case with my redhat system. By diving into the forums I was able to find information to edit my XF86Config file such that it will accept input from my mouse and touchpad at the same time, however the touchpad doesn't have enough functionality that I can use it well. Every time I move it to the left or downwards, it snaps completely to the bottom left corner of the screen and attempts to click whatever is there. Also, when I click something using its left click button, it acts as if I've clicked and held it (for dragging) instead of clicking and releasing. I believe it may be a problem with a driver I told it to use, but I don't know enough about editing config files to be able to know what new driver I would need. These are the edits I made to XF86Config. I added

Section "InputDevice"
Identifier "Mouse2"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/psaux"
Option "ZAxisMapping" "4 5"
EndSection

To make linux aware of the touchpad and I also did

Section "ServerLayout"
Identifier "layout1"
Screen "screen1"
Screen "screen2" RightOf "screen1"
InputDevice "Keyboard1" "CoreKeyboard"
InputDevice "Mouse1" "CorePointer"
InputDevice "Mouse2" "SendCoreEvents" #this was the line that I added
EndSection

Thanks for any help that you may be able to provide.

I have no technical information about the touchpad itself, and I don't recall the command in linux to make it give me hardware information, though if someone could give that to me I would post the output here.

try installing without a mouse plugged in

On my Inspiron 4000, I discovered that if I installed Mandrake 9.2 without the mouse plugged in, then it would properly configure both the mouse and the touchpad (could use them at the same time, touchpad behaved properly).

If I installed with a mouse in the port (not USB), then it skipped the touchpad altogether.

I didn't need to edit any config files, etc. I hope you can solve your problem the same way!

I think this post contain valuable information for you.

I think you will have to mix your current configuration with this one to make it work. Try this

Section "ServerLayout"
Identifier "layout1"
Screen "screen1"
Screen "screen2" RightOf "screen1"
InputDevice "Keyboard1" "CoreKeyboard"
InputDevice "Mouse1" "CorePointer"
InputDevice "TouchpadMouse" "SendCoreEvents"
EndSection


#ADDED FROM LINUXQUESTIONS
Section "InputDevice"
Identifier "TouchpadMouse"
Driver "mouse"
# Option "CorePointer"
Option "Device" "/dev/psaux"
Option "Protocol" "IMPS/2"
Option "Emulate3Buttons" "true"
EndSection

This configuration is (like your current one) for two screens. If you have'nt got more than 1 screen use the Section "ServerLayout" from here
