Package: linux-image-4.9.0-2-amd64
Version: 4.9.13-1

The synaptics touchpad of my X230 thinkpad stopped working as expected
after upgrading to kernel 4.9.
All the "touchpad features" are lost and it operates in generic
pointing device mode. (no tap, no two finger scrolling, no two finger
tap right click)

I compared the output of /var/log/Xorg.0.log in both versions:

The following Xorg config is what I use with 4.8 successfully and
doesn't work anymore with kernel 4.9
My preliminary error analysis: the "MatchIsTouchpad" instruction
doesn't work anymore, because the device is detected as "mouse" with
Kernel 4.9.
BUT - removing that line and using the "MatchDevicePath" with the
"event1" input device (see commented line below) doesn't help.

root@hyperion:~# cat /usr/share/X11/xorg.conf.d/50-touchpad.conf
Section "InputClass"
Identifier "Flos touchpad"
# MatchDevicePath "/dev/input/event1"
MatchIsTouchpad "on"
Driver "synaptics"
Option "Tapping" "on"
Option "TappingButtonMap" "lrm"
Option "VertScrollDelta" "-111"
Option "HorizScrollDelta" "-111"
Option "HorizTwoFingerScroll" "true"
Option "TapButton1" "1"
Option "TapButton2" "3"
EndSection


- Thanks for your help

Florian
