minor problems with 18.04

[Lloydb39]

I upgraded on my homebuilt AMD machine and saw a number of errors flash by on the terminal but surprisingly few problems... so far. Main one seems to be the mouse. It is flakey. Sometimes takes two left clicks, sometimes one right click to make anything work that used to work with one left click. Mouse settings are ok. Any suggestions?
Another thing was I chose to replace "sane" instead of keeping the old one and it didn't seem to like that. What does it do?

Nothing about the mice except to try cleaning it. Might help. I've seen a few mice issues in these forums recently and experienced 1 myself. I ended up swapping in a 10 yr old mouse and retired a mouse from 1999 that was full of more cruft than I would have thought possible.

Sane is a CLI tool for scanning. Usually, we would use some other GUI tool to do scanning. I use gscan2pdf which probably uses sane behind the scenes. But I don't use it that often - basically just in April. ;)

I don't have 18.04. Too new for me.
