Logitech Marble Mouse and X
 

I have a Logitech Marble Mouse, what should my XF86Config file look like? i tried using just the standard two button microsoft mouse protocol and it didn't work. the pointer would jerk around erratically and stick to the upper left corner. now, this is just in straight X, no windows manager, would that be part of the problem?

Dysfunctional Marble Mouse
 

I'm having the same problem...

I have a marble mouse USB going through a PS/2 adaptor and then through a KVM, I suspect this may be the issue. Are you using USB or PS/2?

Here is the relevant sections of my xorg.conf...but it doesn't work...I have tried *ALL* protocols to no avail.

Section "InputDevice"
Identifier "MarbleMouse"
Driver "mouse"
Option "Protocol" "Auto"
Option "InputFashion" "Mouse"
Option "Buttons" "5"
Option "ZAxisMapping" "4 5"
Option "Device" "/dev/mouse" #/dev/input/mice
#Option "EmulateWheel" "1"
#Option "EmulateWheelButton" "4"
#Option "EmulateWheelInertia" "3"
EndSection

Section "ServerLayout"
Identifier "Simple Layout"
Screen "Screen 1"
InputDevice "MarbleMouse" "CorePointer"
InputDevice "Keyboard1" "CoreKeyboard"
EndSection


I ran into this problem on my Slackware box too. The Slackware seems to handle the mouse OK with kernel 2.4, but is erratic with 2.6.

What kernel are you running?
