[pkg-cinnamon] Bug#823843: cinnamon-common: Touchpad setting "tap to click" stopped working

[Christian Pietsch]

Package: cinnamon-common
Version: 2.8.7-1
Severity: normal

Dear Maintainer,

an update to Debian-testing about two weeks ago broke my touchpad's
tap-to-click capability. I had configured it in Cinnamon settings
(/usr/share/cinnamon/cinnamon-settings/cinnamon-settings.py) via the
GUI. The "tap to click" switch is still on, but now I have to use a
physical button above the touchpad in order to click.

my hardware: 3rd generation Lenovo Thinkpad X1 Carbon.

The Debian wiki <https://wiki.debian.org/SynapticsTouchpad> does not
help a lot here:

$ egrep -i 'synap|alps|etps' /proc/bus/input/devices
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=synaptics-pt/serio0/input0

$ synclient -l
Couldn't find synaptics properties. No synaptics driver loaded?

$ syndaemon -d -t -k -i 1
No synaptics properties on device 'SynPS/2 Synaptics TouchPad'.

I have not yet started to fiddle with Xorg configuration files – I am
still hoping this no longer necessary.

Cheers,
Christian
