I think that I had the same problem. I fixed it with:
sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps
sudo dpkg-reconfigure xserver-xorg-input-synaptics
cd /etc/udev/rules.d
sudo nano touchpad.rules
Paste:
ACTION!="add|change", GOTO="xorg_synaptics_end"
KERNEL!="event*", GOTO="xorg_synaptics_end"
ENV{ID_INPUT_TOUCHPAD}!="1", GOTO="xorg_synaptics_end"
ENV{x11_options.MaxTapTime}="300"
LABEL="xorg_synaptics_end"
sudo reboot

Title:
'Synaptics Touchpad' incorrectly detected as PS/2 mouse in 'Lenovo
Thinkpad x120e AE' suddenly
Status in linux package in Ubuntu:
Incomplete
Bug description:
1.Laptop model: LENOVO Thinkpad x120e 0611-AE5
2.Manufacturer of the Touchpad: Synaptics
3.When the symptom first appeared: around 3 month ago (August 2017)
I first encountered this issue after dual boot Linux Ubuntu-MATE 16.04
LTS and Windows 10. My system always update. Touchpad suddenly not
working when the laptop woke up from sleep in Windows 10 OS.
Tried to add parameters in GRUB: quiet splash i8042.reset
i8042.nomux=1 i8042.nopnp=1 i8042.noloop=1 without any positive result
(touchpad still not working), but, now xinput detect PS/2 Generic
Mouse for touchpad (before touchpad is not detected at all).
Attached dmesg and devices file.
Thanks.
Regards,
ariefcfa
