Bug#665004: possible "solution"

[A Mennucc <debdev@mennucci.sns.it>]

hi,

I found a "solution" for this bug.

I look into the GIT repo for this package.

I noted in the changelog of 1.5.99.901-1 the following line:
 Multitouch isn't enabled yet (it would require a newer server anyway).

Looking into configure.ac I spotted
 PKG_CHECK_MODULES(XI22, [inputproto >= 2.1.99.3] [xorg-server >= 1.11.99.901], HAVE_XI22="yes", HAVE_XI22="no")
 if test "x$HAVE_XI22" = xyes; then
     AC_DEFINE(HAVE_MULTITOUCH, 1, [XI2.2 available])
 fi
but currently in Debian/testing x11proto-input-dev=inputproto is at 2.1 
and  xserver-xorg-dev=xorg-server is at 1.11.4
whereas in Debian/experimental   x11proto-input-dev is at 2.1.99.6-1 , 
 xserver-xorg-dev is at  1.12.0-1

So I issued
# apt-get -t experimental install x11proto-input-dev xserver-xorg-dev
and moreover it turned out that I needed
# apt-get install libmtdev-dev

This way I could compile the "synaptics" module with multitouch enabled;
unfortunately the resulting module has ABI 16, whereas the server has ABI 13;
to install the server from experimental, I also had to recompile
 xserver-xorg-input-evdev so that it now has ABI 16 as well.

I installed the synaptics and evdev modules, and the server from 
experimental, and it all works fine.

I attach anyway the patch to the GIT repo.

So the solution may be to upload a version with my patch to experimental,
and similarly for x---evdev, so people that want to upgrade 
and still use multitouch may use that; and in due time move it all to 
unstable and to testing.

NB : I use the proprietary nvidia driver ; I did not recompile it in any 
 way :-)

a.

ps: And, just in case I can confirm the bug . I use a MacBook 5.1.
 Both actions:
  swipe two fingers on pad -> scrolling
 and
  click on touchpad with two/3 fingers ->  right/center mouse click
 do not work with the synaptic package now in unstable.
