Hi,
There is a new evdev input driver merged into upstream which works
much better than the old system (at least for me trying to use a Apple
Mighty Mouse on a IA64 system with udev, which I guess not many people
do!)
In general this input driver seems much better than the older version,
which is not supported upstream.
I removed the 053_lnx_evdev.diff, 054_lnx_evdev_mouse.diff and
055_lnx_evdev_keyboard.diff patches and added the attached, and
rebuilt (this patch also adds a small patch to enable horizontal
scrolling with my Mighty Mouse, see
https://bugs.freedesktop.org/show_bug.cgi?id=4316). I couldn't figure
out how to get it in the packages with the MANIFEST stuff, but
installing it by hand everything works as expected.
It requires loading the module and changing the mouse line to have
Driver "evdev"
with the correct Device specifier. No need for the "Buttons" options,
etc.
Since upstream have decided this is the version to use and Debian has
to make a transition one day anyway, maybe we could get a head start
with this backport?
