Problems with xf86-input-synaptics 1.7.99.1

[Justin Brown]

Hello,

I saw the announcement for xf86-input-synaptics 1.7.99.1 and decided
to give it a go on my Fedora 20 system since it's supposed to improve
the experience with new Lenovo touchpads. Unfortunately, I'm
experiencing serious problems and am not quite sure where to report
the bug on Bugzilla.

Problem:
=======

The touchpad works fine at first. However, once I use two-finger
vertical scrolling once, the touchpad is permantely stuck in scrolling
mode. Using one finger to reposition the cursor only scrolls the
system. I can left and right click, but never reposition the cursor.

Platform information:
================

There are no messages in the systems logs to indicate anything.

Testing:
======

1. Install and update Fedora 20
2. Update package based on my OBS repository:

cd /etc/yum.repos.d/
wget http://download.opensuse.org/repositories/home:fandingo/Fedora_20/home:fandingo.repo
yum update xorg-x11-drv-synaptics

3. Reboot
4. Use two-finger scrolling

If additional information is needed, I can provide it.

Thanks,
Justin
