I'm not sure if my issue is related:

I upgraded to 4.15.0-24 yesterday (no other updates) and this morning I get a blank screen on boot that sits there indefinitely (i.e. minutes).

To fix this, I CTRL-ALT-F6 to get another tty, which immediately show up. This however seems to trigger some event, as the graphical login appears (displaces) my tty6 terminal without my intervention. So I can reliably get the graphical login back by "playing" with tty6.

One thing I noticed during boot was the `nvidia-persistenced` (using Nvidia's proprietary 390 drivers) service doing a dozen start/stops in quick succession. This doesn't show up every time though, and the blank screen that follows prevents me from seeing more.

`snapd.service` and `unbound.service` appear as the main offenders, but I'm not sure what's cause and effect here.

Booting with the prior 4.15.0-23 kernel works fine, as before.
