Dual-Mouse Configuration ... Confusion ?

orbit · 02-04-2010, 03:02 AM

Hi all,

I'm trying to run two mice at the same time and after reading many posts about this, I have not been able to find a resolution theme, or a fix that works for my setup.

My Setup:
I have one mouse connected via a ps2 kvm-switch which is my 'general' mouse and it works fine.

I have another 'gaming' mouse which is an optical ps2 adapted through a usb adaptor into usb port and won't work at all, (the optical light is running, but no cursor movement).

Attempted fixes:
1. I have run 'mouseconfig' , chosen usbmouse ... nothing changed.

2. Attempted adding a second mouse section to xorg.conf, but do not think I had it setup right.
e.g.

Code:

Section "InputDevice"
    Identifier     "Mouse1"
    Driver         "mouse"
    Option         "Protocol" "IMPS/2"
    Option         "Device" "/dev/input/mouse1"
    # (  # /dev/mouse, uncomment /dev/psaux )
    Option         "Resolution" "300"
    Option         "ZAxisMapping" "4 5"
    Option         "Buttons" "3"
EndSection

Section "InputDevice"
    Identifier  "Mouse2"
    Driver      "mouse"
    Option "Protocol"    "IMPS/2"
    Option "Device"      "/dev/input/mouse0"
    Option "Buttons" "3"
    Option "ZAxisMapping" "4 5"
EndSection

3. Also, I read in another post to do this command: dmesg | grep -i mouse, but I am not sure how to utilise the output?

Quote:

dmesg | grep -i mouse
input: Macintosh mouse button emulation as /devices/virtual/input/input0
mice: PS/2 mouse device common for all mice
input: ImPS/2 Generic Wheel Mouse as /devices/platform/i8042/serio1/input/input4

Could anyone please offer some pointers?

My O.S. environment: Slackware 12.1 +KDE3.5.10 +2.6.24.5smp

Thanks very much for any help

Cheers

You've defined your two mice using the 'Section "InputDevice"' entries.
Have you also placed corresponding InputDevice entries in the 'Section "ServerLayout"' definition ?

For example; my xorg.conf for Slackware 13.0 on my laptop that has a built-in touchpad and also uses a serial mouse; via a KVM; when placed in it's docking station. Has mouse definitions similair to yours. But it also has these two entries for the mice in the 'Section "ServerLayout"'

Code:

InputDevice "Mouse0" "CorePointer"
InputDevice "Mouse2" "SendCoreEvents"

Plus; since Slackware 13.0's xorg works different than Slackware 12.1 (or is it due to HAL ?). I also had to place these two lines in the Section "ServerLayout"'

Code:

Option "AllowEmptyInput" "false"
Option "AutoAddDevices" "false"

Hope this is of help.

Have you tried starting X without an xorg.conf? I did this with my xbox controller plugged in and the mouse and the controller moved the cursor.

Post #2 worked for me in the past. Note that "sendcoreevents" is, IIRC, the same as "alwayscore", though one wording may have superceded the other on newer versions of X.

I have no idea if the KVM aspect affects this or not
