I have a generic (a la Clevo) laptop with a synaptics touchpad.
Today, my configuration randomly stopped working.
I hadn't updated anything and I haven't changed the configuration file.
I know that actual touchpad hardware is functioning because I booted into Windows and the touchpad functions normally.
It's all very mysterious.
Here's the configs and logs for the touchpad:
70-synaptics.conf
# Example xorg.conf.d snippet that assigns the touchpad driver
# to all touchpads. See xorg.conf.d(5) for more information on
# InputClass.
# DO NOT EDIT THIS FILE, your distribution will likely overwrite
# it when updating. Copy (and rename) this file into
# /etc/X11/xorg.conf.d first.
# Additional options may be added in the form of
# Option "OptionName" "value"

Have you tried: xinput disable 12 ? Then xinput enable 12?

I ended up fixing the issue by upgrading to the generic libinput driver.
