I've never had to do anything special to my xorg.conf, but it no longer responds for KDE. Definitely not broken hardware because you can see it connecting:
[ 320.016064] usb 5-3: new low speed USB device number 4 using ohci_hcd
[ 320.166344] usb 5-3: New USB device found, idVendor=046d, idProduct=c402
[ 320.166356] usb 5-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 320.166373] usb 5-3: Product: USB-PS/2 Trackball
[ 320.166385] usb 5-3: Manufacturer: Logitech
[ 320.173969] input: Logitech USB-PS/2 Trackball as /devices/pci0000:00/0000:00:13.0/usb5/5-3/5-3:1.0/input/input7
[ 320.174712] generic-usb 0003:046D:C402.0004: input,hidraw0: USB HID v1.00 Mouse [Logitech USB-PS/2 Trackball] on usb-0000:00:13.0-3/input0

Anyone had to change their xorg.conf?

My ServerLayout section only includes a PS/2 mouse:
Section "ServerLayout"
Identifier "XFree86 Configured"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "PS/2 Mouse" "CorePointer"
EndSection

I also don't have an xorg.conf.d directory in /etc/X11...just an xorg.conf file and multiple backups of it...


Added this to my xorg.conf as mentioned by (https://help.ubuntu.com/community/Logitech_Marblemouse_USB), but it doesn't help either:
Section "InputClass"
Identifier "Marble Mouse"
MatchProduct "Logitech USB Trackball"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
Option "ButtonMapping" "1 2 3 4 5 6 7 8 9"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "8"
Option "ZAxisMapping" "4 5"
Option "XAxisMapping" "6 7"
Option "Emulate3Buttons" "true"
EndSection

I would suggest, remove your xorg.conf.
Recent Xorg does not need such config-file.

I'm currently using a Logitech trackball with the following added to "/usr/share/X11/xorg.conf.d/10-evdev.conf"


      Code:
Section "InputClass"
        Identifier  "Marble Mouse"
        MatchProduct "USB Trackball"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option "ButtonMapping" "1 2 3 4 5 6 7 8 9"
        Option "EmulateWheel" "true"
        Option "EmulateWheelButton" "8"
        Option "EmulateWheelInertia" "10"
        Option "ZAxisMapping" "4 5"
        Option "XAxisMapping" "6 7"
        Option "Emulate3Buttons" "true"
        Option "AccelerationNumerator" "15"
        Option "AccelerationDenominator" "1"
        Option "AccelerationThreshold" "4"
EndSection


I'm not 100% certain, but I believe that the "MatchProduct" section should be "USB-PS/2 Trackball" for your setup.

And I agree with Towo. You don't really need the xorg.conf file.

One more thing. This file seems to get replaced at times when doing a dist-upgrade, so if your trackball stops working after an upgrade you might need to add this code again.

Thanks....I put that config w/ "USB-PS/2 Trackball" into a new 50-marblemouse.conf in /usr/share/X11/xorg.conf.d and it works now.
Gumper: you might want to put it in a separate file...you're modifying a file that's part of the Xorg distribution probably.

Thanks for the xorg.conf removal tip too...my desktop comes up at a higher resolution now Smile

Don't ever write into /usr/share/X11/xorg.conf.d/, use /etc/X11/xorg.conf.d/ instead.

I don't have an /etc/X11/xorg.conf.d directory. Should I just create one? Weird that that ubuntu page said it's supposed to go there too..

If you don't have it, create it - /etc/X11/xorg.conf.d/ takes precedence over /usr/share/X11/xorg.conf.d/ and is the only place that allows system specific modifications.
