symlink question


This is confusing for me. I read man symlink but it doesn't help. this is what I want to do:

Quote:
5.1. Using an external USB pointer device in X
Most people want both the stick/touchpad working full-time,
and to be able to plug in an external USB mouse whenever they
want and have it work without having to retool XF86Config each
time. I have successfully done this with the following
sections in my XF86Config-4:
Section "InputDevice"
# This section controls the stick/touchpad
Identifier "Mouse0"
Driver "mouse"
Option "Device" "/dev/psaux"
Option "Protocol" "PS/2"
Option "Emulate3Buttons" "on"
EndSection

Section "InputDevice"
# This section controls an optional USB mouse
Identifier "USBMouse"
Driver "mouse"
Option "Device" "/dev/pointer"
Option "Name" "AutoDetected"
Option "Protocol" "IMPS/2"
Option "Vendor" "AutoDetected"
Option "ZAxisMapping" "4 5"
EndSection

Next, modify the "ServerLayout" section to look something like:
Section "ServerLayout"
Identifier "MyXLayout"
Screen "Screen0"
InputDevice "Mouse0" "CorePointer"
InputDevice "USBMouse" "SendCoreEvents"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
This tells the Xserver to always look for Mouse0, and barf if
it's not there (which hopefully will never happen), and if the
USBMouse is detected on /dev/pointer, then have it send core
signals to the Xserver, but don't barf if it can't find it.

Last note, make sure you make a symbolic link from
/dev/input/mice (this is on the 2.4.x kernel) to /dev/pointer

when I tried
Code:
symlink /dev/input/mice /dev/pointer
it returned an error like this:
bash: symlink: command not found

help!

You're almost there mate ...

man (2) symlink is what you read, it's
programming information. Look at the bottom
of that manpage, find the man page entry
with (1), namely ln, and enjoy :)

ln -s /dev/input/mice /dev/pointer
is what you want to do ;)

Cheers,
Tink
