Well, I *think* I can answer my own question about the signed image.

The signed image was *not* generated by my installing the lp1759920 kernel.
In fact it is the identical file to the one from:
  https://launchpad.net/ubuntu/+archive/primary/+files/kernel-signed-image-4.13.0-38-generic-di_4.13.0-38.43_amd64.udeb
(which is a link from https://launchpad.net/ubuntu/+source/linux-signed).

Given that no similar package is installed on my system for *any* signed kernel image I'm at a loss to know how and when they *do* get signed.

But this does explain why my laptop still hangs - it's because it isn't actually running the lp1759920 kernel.

Is there any (simple-ish) way to generate a signed image from the unsigned one?
