Red Hat Bugzilla – Bug 436405
f9 xorg no longer honors my mouse settings
Last modified: 2008-08-03 19:35:00 EDT
Description of problem:
I have a logitech trackball that I have a custom xorg configuration for so I can
emulate scrolling by holding one of the special buttons and then rolling the
trackball. I've had this configuration since fc6 and it has worked fine, now
all of a sudden its not working. It does however do what it would do in
windows/OS x, where if i press the side buttons it will scroll the window up and
down, which is cool that the driver now recognizes that, however I like my
configuration _much_ better.
Version-Release number of selected component (if applicable):

Hmm, I thought this might be related to evdev, so I did a
but for some reason it still loads. If i look at my Xorg.0.log I see it say
"evdev will not be loaded", but it still loads it, and my config is still ignored.
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
You're seeing a conflict between hotplugged input devices and the actual
devices. These are added with the evdev driver, and default options.
Furthermore, evdev grabs the device file, so any device added through hotplug
won't feed into /dev/input/mice (i.e. all mice).
In your case, this means that your mouse is still there, but since all devices
stopped sending to /dev/input/mice it doesn't send any events.
The only option for now is to add "Option "AutoAddDevices" "off" to your
ServerLayout. This deactivates input device hotplugging and the mouse will use
the options specified in the config.
Eventually, evdev should get EmulateWheel support , but upstream doesn't have
it yet. See also 
Closing as NOTABUG, since it was caused by configuration error.
