2 simulataneous mouse devices

kcor · 09-27-2006, 06:14 PM

Just a relatively easy thing I need here, I've just forgotten how I set it up:

I want to simultaneously use my touchpad mouse on my laptop AND my usb mouse...

I can get one working but not the other and vice versa. How can I set this up ?

Also, less of a problem but still annoying at times: My scroll region on my touchpad does not "scroll". It just moves the mouse cursor around. Anyone ever experienced something similar or know of a solution?

-Thanks in advance

The answer is likely in /etc/X11/xorg.conf. You'll need to add the second mouse to your xorg.conf I'm guessing. It will look something like this.

Code:

#
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option      "XkbModel" "pc105"
        Option      "XkbLayout" "us"
EndSection

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "IMPS/2"
        Option      "Device" "/dev/input/mice"
        Option      "ZAxisMapping" "4 5"
        Option      "Emulate3Buttons" "yes"
        Identifier  "Mouse1"
        Driver      "mouse"
        Option      "Protocol" "PS/2"
        Option      "Device" "/dev/input/mice"
        Option      "ZAxisMapping" "4 5"
        Option      "Emulate3Buttons" "yes"
EndSection

In my xorg.conf, as I have a laptop with both a trackball and touchpad, I have the following items for mice:

Code:

Section "InputDevice"
Identifier "Glidepoint"
Driver "synaptics"
Option "ZAxisMapping" "4 5"
Option "CorePointer" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "LeftEdge" "60"
Option "RightEdge" "830"
Option "TopEdge" "70"
Option "BottomEdge" "650"
Option "FingerLow" "25"
Option "FingerHigh" "30"
Option "MaxTapTime" "180"
Option "MaxTapMove" "110"
Option "EmulateMidButtonTime" "75"
Option "VertScrollDelta" "50"
Option "HorizScrollDelta" "50"
Option "MinSpeed" "0.2"
Option "MaxSpeed" "0.8"
Option "AccelFactor" "0.10"
Option "EdgeMotionSpeed" "40"
Option "UpDownScrolling" "1"
Option "TouchpadOff" "0"
EndSection

# Also allow USB mouse
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "SendCoreEvents"
Option "Protocol" "auto"
Option "Device" "/dev/input/mice"
EndSection

This allows for the individual settings of the touchpad to be set. In addition to my trackball working, I can also have my graphics tablet, and gyro-mouse attached to my computer at the same time, and all will work.

I think the key to this setup working is to have CorePointer set on one of the devices, and then SendCoreEvents on the others, so that the other devices will send their events to the core device (you can only have once core device at a time, or else only the first one will do anything)

Thanks so much!!! That seemed to do the trick. I "thought" I had it set the way you do but it did not work back then (maybe had a small typo or something), but I tried your suggestion and everything is fine and dandy again...
