Comment 6 for bug 567068

I just tried this, as /etc/X11/xorg.conf.d/marblemouse.conf:

### START OF FILE ###
Section "InputDevice"
 Identifier "Mouse0"
 Driver "mouse"
 Option "CorePointer"
 Option "Device" "/dev/input/mice"
 Option "Protocol" "auto"
        Option "Buttons" "5"
        Option "ButtonMapping" "1 8 3 2 9"
        Option "EmulateWheel" "true"
        Option "EmulateWheelTimeout" "300" # msec
        Option "EmulateWheelButton" "2"
        Option "YAxisMapping" "4 5"
        Option "XAxisMapping" "6 7"
EndSection
### END OF FILE ###

This caused my X to lock up at the login screen, even after rebooting. I had to power off the machine, as I could not even Ctrl-Alt-F1 to get a text terminal login. After rebooting in recovery mode, I renamed the file (added "_disabled" to the name) and could use X once more.

As I have a Marble Mouse trackball, I'm hoping someone will figure out an actual working config, where I can use the buttons as follows:
Big Left: normal left mousebutton
Small Left: mousebutton 3, used to open new tabs in Firefox, or paste from the selection clipboard
Small Right + ball movement: scroll freely, vertically and horizontally
Big Right: normal right mousebutton

I could do all this with HAL, using this fdi, so hope I'll be able to do so again soon:
