Hi synaptics developers,
In geis-2.2.16, libgeis/backend/grail/geis_grail_backend.c source code
file, about the 1143 line,
http://bazaar.launchpad.net/~oif-team/geis/trunk/view/head:/libgeis/backend/grail/geis_grail_backend.c#L1147
it would get error XEvent type, printf the XEvent type is 84.
My development enviorment shown as below:
3.12.7-2-ARCH i686
xf86-input-synaptics-1.7.3
geis-2.2.16
touchegg svn reversion 189
gnome-shell 3.10.2
I used touchegg, a qt4 gesture recognition application based on geis, to
debug gesture recognition, and my touchpad supports multitouch, for
example mtdev_has_mt_event(mtdev, ABS_MT_SLOT), when I used 3 fingers to
drag, geis got error XEvent type 84 in _x11_fd_callback function.
I argued that it might be xf86-input-synaptics-1.7.3`s issue, because
geis backend only received XEvent, then classified the gesture, but
synaptics post the multitouch event by xf86PostTouchEvent, in
xf86-input-synaptics=1.7.3 src/synaptics.c, about the line 2710,
http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/tree/src/synaptics.c?h=synaptics-1.7-branch#n2710
And why ubuntu phone with multitouch touchscreen works well? It is based
on Mir, utouch-geis, sort of gesture recognition utils, is not it? or it
is android-based, different from Linux multitouch protocol?

please someone give me some advice, thanks a lot!
Regards,
Leslie Zhai
