After an upgrade to 17.10 internal keyboard and touchpad suddenly stopped working. This problem occurs even during startup, so I can't even boot from USB. This problem probably occured after I created a new user account, but I deleted it in the meantime and no change. After the installation, everything worked still well. However, I can use external USB mouse. Can someone please help me? I'm completely lost.

Or can this be a hardware problem? Thanks a lot!
For me wifi was stopped working after couple of restarts, post 17.04 to 17.10 upgrade. I chose earlier stable version of kernel from grub, and things are running fine now. You may want to check out
dmesgoutput, that's how i got the hint that something is wrong around it.
