Touchpad working with evdev driver instead of synaptics

Hello.
My device is HP Split 13-m101 x2 (2-in-1, clickpad is in the dock-station).

Evdev driver is loaded, clickpad is working, but scrolling does not work and i can left click only in bottom left (like classic touchpad), not everywhere on clickpad.
I added to /etc/X11/xorg.conf.d/10-synaptics.conf this:

Section "InputClass"
      Identifier "evdev pointer catchall"
      Driver "synaptics"
      MatchDevicePath "/dev/input/event14"
EndSection

and reboot xorg. Touchpad stopped working.

I tried

Option "Protocol" "auto"

and

Option "Protocol" "auto-dev"

in /etc/X11/xorg.conf.d/10-synaptics.conf. The same result.
Sorry for my English.
Any help?
