Bug#754822: same problem with a ALPS device

[Fred Maranhão <fred.maranhao@gmail.com>]

hi,

during an apt-get upgrade today, my xserver-xorg-input-synaptics was
upgraded to 1.8.0-1 and the same problem arise.

I'm not using an Elantech mouse, but an ALPS:

$ egrep -i 'synap|alps|etps' /proc/bus/input/devices
N: Name="ALPS PS/2 Device"
N: Name="AlpsPS/2 ALPS GlidePoint"

I noticed the problem in GDM login screen, xfce and fluxbox.

If I plug an external usb mouse, the pointer moves normally with the
mouse and slowly with the touchpad.
