multiple mice

ramack · 06-07-2006, 11:12 PM

Hi,

I have a ps/2 pointer and want to add a USB mouse. I can get both to work separately via mouseconfig, but how can I configure such that both will work.

Mouse #1 is a generic 2 button mouse. Mouse #2 is a Logitech 3 button wheeled mouse.

Thanks,

Rich

Welcome to LQ!

This is what I have in /etc/X11/xorg.conf:

Code:

#    Option "ChordMiddle"
    Identifier     "Mouse1"
    Driver         "mouse"
    Option         "Protocol" "IMPS/2"
    Option         "ZAxisMapping"  "4  5"
# The mouse device.  The device is normally set to /dev/mouse,
    Option         "Device" "/dev/mouse"
#   Option "Device"      "/dev/psaux"

on my wife and daughter's Slackware box.
One PS/2 and one USB mouse working fine together.

For my xorg.conf I have separate sections for each mouse, then include them both in the layout section. So you could also try something like this:

Code:

Section "InputDevice"
    Identifier  "USB Mouse"
    Driver      "mouse"
    Option      "Device"            "/dev/input/mice"
    Option      "SendCoreEvents"    "true"
    Option      "Protocol"          "IMPS/2"
    Option      "ZAxisMapping"      "4 5"
    Option      "Buttons"           "5"
EndSection

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

Section "ServerLayout"
    Identifier  "Simple Layout"
    Screen      "Screen 0"
    InputDevice "PS/2 Mouse" "CorePointer"
    InputDevice "USB Mouse" "SendCoreEvents"
    InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Notice the 'SendCoreEvents' and 'CorePointer'. VERY important for two to work together.

I always keep my touchpad as 'CorePointer', and my USB as 'SendCoreEvents'

Silly me, I'm not using the "SendCoreEvents":

Code:

anna@peter:~$ cat /etc/X11/xorg.conf | grep -i SendCoreEvents
#    Option     "SendCoreEvents"
#    Option     "SendCoreEvents"
# "SendCoreEvents".
anna@peter:~$ cat /etc/X11/xorg.conf | grep -i CorePointer
# used.  Those options include "CorePointer", "CoreKeyboard" and
    InputDevice    "Mouse1" "CorePointer"

and they work just fine.

My touchpad requires it, and it's not a bad idea to do so anyways (Keeps me straight/honest about what is primary, what is added on...lol)

It's absolutely not necessary here..

From 'man xorg.conf'

Code:

Option "CorePointer"
              When  this  is  set,  the  input device is installed as the core
              (primary) pointer  device.   There  must  be  exactly  one  core
              pointer.  If this option is not set here, or in the ServerLayout
              section, or from the -pointer  command  line  option,  then  the
              first  input  device  that  is  capable  of being used as a core
              pointer will be selected as the core pointer.   This  option  is
              implicitly set when the obsolete Pointer section is used.

And

Code:

Option "SendCoreEvents"  "boolean"
              Both of these options are equivalent, and when enabled cause the
              input device to always report core events.  This  can  be  used,
              for  example,  to allow an additional pointer device to generate
              core pointer events (like moving the cursor, etc).

While it may not be neccesary, it is good practice.
