I hooked up my old wired keyboard and mouse that came with my Emachine computer. I'm glad I saved them. So far not a freeze, everything is running great. In a couple days if there hasn't been a lockup, I'll put new batteries in my wireless keyboard and mouse and try that out again. If it freezes up again after that, then I'll just use my wired keyboard/mouse permanently.
Oh and I'm getting update notifications again after going to 20.04 LTS
I was getting none anymore with 20.10.
