Lost my mouse and keyboard on upgrade

in flag

I'm running 18.04 LTS and just did an automatic maintenance upgrade. The kernel versions are 5.4.0-91-generic (previous) and 5.4.0-92-generic (current)

After today's upgrade, the mouse and keyboard are not recognized. If I use Grub to boot to ...91 all is well. Keyboard works fine in Grub. On ...92 I get the login screen but cannot log in without mouse or keyboard

I've tried booting to a shell with /bin/bash in the Grub line. This does nothing. I can boot to run level 3 using Grub but the keyboard is still not recognized so I can't enter commands

FWIW, I'm using a KVM switch, America Megatrends micro PC, and generic usb keyboard and wireless mouse

This same thing happened when I did a dist-upgraded to 20.04 LTS so I had to back it out

Any help would be most appreciated. I'm stuck

Can you try without the KVM switch? Or with a different keyboard? Can you access the machine over SSH?

Thanks so much for your reply. I've removed the KVM switch and no difference. The machine is otherwise functioning properly as I can ping and ssh to the machine.

Can you ssh to it and check `/var/log/apt/history.log` to see if something was uninstalled? A bit of a long shot, but it happened to me once that `xserver-xorg-input-all` was removed when installing a package, resulting in no keyboard or mouse input to the x server.

I've checked my apt history, starting with the upgrade that started the problems, which incidentally was the start of the log. There is an entry where I tried re-installing xserver but this was long after the problem started. Nothing has been removed. Sadly, there's not room to paste the log in the comment

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
