If I select 4.15.0-47-generic, it boots up just fine to a completely usable desktop. Every time. I've tried running boot-repair. It reported that it had repaired GRUB, but the problem persists. So I don't think its a boot parameters problem. I conclude that the problem has something to do with the display driver in 4.15.0-48-generic that was not present in 4.15.0-47-generic.
