[ubuntu] After monitor swap, keyboard and mouse no longer work?!?

So I had a crappy 4:3 monitor with bad coers and a line, DVI hookup and I swapped it for a 16:10 one that looks much better, and of course everything was plug and play on the Windows 10 side. Trouble is, after Grub when I try to login to Ubuntu 16, I can't get anything out of the keyboard or mouse, with no other things changed. Anyone have any ideas?

I tried unplugging and re-plugging them in while it's in the login screen, to no avail.
