I have an Evo N800W laptop workstation on which I installed Linux (RedHat
9.0). Due to some Xconfig corruption problems I had to manually put back
an older backup copy of the config file. Everything started working fine
except my system now does not auto detect the laptop's touchpad or an external
USB mouse that is already attached at the boot up time. It detects the USB
mouse that I plug in (or unplug or plug back in) after the OS has booted
up and never detects the touchad. Any fixes for this so I can use the laptop's
mouse pad and have the external mice detected at boot up automatically?
Thanks much!

P.S. If you could also email your response directly to me it would be greatly
appreciated.

You will need to modify your XF86Config file (probably
/etc/X11/XF86Config) to use two mice. Here is how I do it on my laptop:

In the section ServerLayout:

InputDevice "Mouse0" "CorePointer"
InputDevice "Mouse1" "SendCoreEvents"

Then, below this:

Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "ps/2"
Option "Device" "/dev/psaux"
EndSection

Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Buttons" "5"
Option "Device" "/dev/input/mice"
Option "Protocol" "IMPS/2"
Option "ZAxisMapping" "4 5"
Option "Resolution" "500"
EndSection

Mouse 0 is the touchpad, Mouse 1 is the usb mouse. You may need to
change the Protocol to get it to work; I don't have the same laptop as
you. My mouse is a Logitech optical mouse (not sure of the model#).

It goes without saying that you also need the appropriate kernel
modules, but if it was working before and now doesn't work solely due to
a change in your XF86Config file, then you probably already have the
modules.
