I've been having a super bizarre problem recently. About a week ago, I reinstalled Ubuntu on my dual-booted Dell XPS 15, since my keyboard and mouse were not working. The os itself was still fine (ie it wasn't frozen), but neither external keyboards/mice nor my internal keyboard/touchpad were responsive. After a week, it looks like the problem has occurred again on a relatively fresh install of Ubuntu.
I have tried reinstalling xserver and xserver-input as talked about in this question: Updated from 16.04 to 16.10; the keyboard and mouse no longer works after getting to the lock screen
Digging into it a bit, I noticed that there was a package named xserver-xorg-input-all and xserver-xorg-input-all-hwe-18.04. What are their differences, and what should I have installed?
This happened after a reboot of my system, and I don't remember installing or removing anything specifically. Any help would be appreciated!
Cheers!
