How can I make my mouse work in my laptop? Currently, my XF86Config is like this:

Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "PS/2"
Option "Device" "/dev/mouse"
EndSection

that works well with that little green ball in the middle of the keyboard, but I want to use my external mouse. I tried to add another "InputDevice" as both "/dev/psaux" or another "/dev/mouse", as I saw in another post, and add it to "ServerLayout", but it either freezes everything or simply does not work at all. I'm running Slackware 9.1 in a Toshiba 2065CDS laptop.

Any help?

Thanks
