Regarding psmouse.synaptics_intertouch=1

I had following in `dmesg`:

[    4.074260] psmouse serio1: synaptics: Your touchpad (PNP: LEN0099 PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@vger.kernel.org

But enabling `psmouse.synaptics_intertouch=1` resulted in following `/var/log/Xorg.0.log`:

[    19.747] (II) config/udev: Adding input device Synaptics TM3418-002 (/dev/input/event12)
[    19.747] (II) No input driver specified, ignoring this device.
[    19.747] (II) This device may have been added with another device file.

And touchpad with trackpoint remain disabled completely.

My `/etc/X11/xorg.conf.d/synaptics.conf` is the following:

Section "InputClass"
        Identifier "Mouse0"
        Driver "synaptics"
        MatchIsTouchpad "on"
        Option "VertTwoFingerScroll" "on"
        Option "HorizTwoFingerScroll" "on"
        Option      "CircularScrolling"         "on"
        Option      "VertScrollDelta"          "-111"
        Option      "HorizScrollDelta"         "-111"
        Option      "TapButton1"                  "1"
        Option      "TapButton2"                  "3"
