I have been using Xubuntu 16.04 since June 2016 on my Lenovo Thinkpad T440p (i5-4210M, 16GB RAM, NVIDIA 730M). However since last year (probably after a kernel upgrade), my touchpad has stopped working (I always keep the system upgraded via apt update/upgrade. It doesn't work at all, and I have to use an external mouse.
Only very rarely, it somehow works as well (by rare I mean twice in the last two years), but as soon as I reboot, the state is back to non-working at all. Additionally, even when working in those two rare occasions, the touchpad behaved erratically, i.e., the tap click was not working and the pointer was kind of jumpy.
As per the description at https://wiki.ubuntu.com/DebuggingTouchpadDetection, I uploaded an archive touchpad_debug.tar.gz containing two sub-folders working_state and nonworking_state to google drive. Each folder contains the dmesg output, my /proc/bus/input/devices, and my /var/log/Xorg.0.log when the touchpad was working and not working. In working_state, I additionally have the outputs to "xmodmap -pp", "xinput --list ", and "xinput --list-props ".
I have tried updating the BIOS and reinstalling xserver-xorg-input-synaptics. Nothing has helped so far.
Could anyone please help me figure out the solution to the non-working Synaptics Touchpad?

PS: As per Ubuntu's DebuggingTouchpadDetection link above, I went ahead and posted a bug report (bugs.launchpad.net/ubuntu/+source/linux/+bug/1763755) but it was also recommended to take help from here, therefore this post.
