The issue seems to be fixed today: my touchpad is now working, and appears in cat /proc/bus/input/devices. I didn't do anything new inbetween, so I can't explain why it's back to normal.

I executed this at at a terminal : cat /proc/bus/input/devices but there was no touchpad in the list. I read this page (https://wiki.ubuntu.com/DebuggingTouchpadDetection) and found out it must be a bug related to the kernel. I'm attaching the result of the cat /proc/bus/input/devices command.
