# 4.5. Using independent mice with XFree

To use an independent mouse for each of your independent X servers/sessions, you just have to modify the input section of the XFree configuration files to point to the proper device files.

Use `/dev/input/mouse[n]`, where n is the number of your mouse starting from 0:

- 1st mouse --> `/dev/input/mouse0`

- 2nd mouse --> `/dev/input/mouse1`

- 3rd mouse --> `/dev/input/mouse2`

- 4th mouse --> `/dev/input/mouse3`

You shouldn't use `/dev/input/mice` because it merges the input from all mouse devices.

Here is my configuration before modifications:

    ------------------------------------------------------------------------------------------------

    # **********************************************************************
    # Pointer section
    # **********************************************************************

    Section "InputDevice"

        Identifier  "Mouse1"
        Driver      "mouse"
        Option "Protocol"    "IMPS/2"
        Option "Device"      "/dev/psaux"
        Option "ZAxisMapping" "4 5"

    # ChordMiddle is an option for some 3-button Logitech mice
        Option "Emulate3Buttons"
    #    Option "ChordMiddle"

    EndSection

    ------------------------------------------------------------------------------------------------

After modifications for the first X server:

    ------------------------------------------------------------------------------------------------

    # **********************************************************************
    # Pointer section
    # **********************************************************************

    Section "InputDevice"

        Identifier  "Mouse1"
        Driver      "mouse"
        Option "Protocol"    "IMPS/2"
        Option "Device"      "/dev/input/mouse0"
        Option "ZAxisMapping" "4 5"

    # ChordMiddle is an option for some 3-button Logitech mice
        Option "Emulate3Buttons"
    #    Option "ChordMiddle"

    EndSection

    -----------------------------------------------------------------------------------------------

For the second X server:

    -----------------------------------------------------------------------------------------------
    # **********************************************************************
    # Pointer section
    # **********************************************************************

    Section "InputDevice"

        Identifier  "Mouse1"
        Driver      "mouse"
        Option "Protocol"    "IMPS/2"
        Option "Device"      "/dev/input/mouse1"
        Option "ZAxisMapping" "4 5"

    # ChordMiddle is an option for some 3-button Logitech mice
        Option "Emulate3Buttons"
    #    Option "ChordMiddle"

    EndSection
    -----------------------------------------------------------------------------------------------

and so on ...
