Day before yesterday, I updated Ubuntu in my laptop, then the next morning when I try to use touch-pad it wasn't working, I switched to windows to see whether touch-pad was working or not, it was working fine. Here's the details

Could you please check if it works when booting a previous kernel?
This is not a bug in unattended-upgrades for sure, but a regression in something installed by it.
