Public bug reported:
I use a Logitech Marble Mouse trackball, and have a hal policy file
setup with the following rules:
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<match key="info.product" string="Logitech USB Trackball">
<merge key="input.x11_options.ButtonMapping" type="string">1 8 3 2 9</merge>
<merge key="input.x11_options.EmulateWheel" type="string">true</merge>
<merge key="input.x11_options.EmulateWheelButton" type="string">8</merge>
<merge key="input.x11_options.ZAxisMapping" type="string">4 5</merge>
<merge key="input.x11_options.Emulate3Buttons" type="string">true</merge>
</match>
</deviceinfo>
This allows me to emulate a middle mouse button by clicking the two
large left and right buttons simultaneously, and also lets me emulate a
scroll wheel by clicking the small left button while scrolling the
trackball.
Somewhere between xorg-server 2:1.5.99.901-1ubuntu1 and
2:1.5.99.902-0ubuntu3, this broke.
xinput shows that the evdev propeties are being set correctly (at least,
this output is the same with both versions of xorg-server:
tooj...@yoshi:~$ xinput --list-props "Logitech USB Trackball"
Device 'Logitech USB Trackball':
Device Enabled (93): 1

Evdev Wheel Emulation Inertia (233): 10
Evdev Wheel Emulation Timeout (234): 200
Evdev Wheel Emulation Button (235): 8
Evdev Drag Lock Buttons (236): 0
Downgrading to xorg-server 2:1.5.99.901-1ubuntu1 "fixes" this issue for
me.
