Thank you all for your suggestions.

There is no 'sleep' option in Cinnamon, only 'suspend'.

But selecting 'suspend' from the Shutdown menu item works, then close 
the lid.

On opening the lid, I get the lock screen and can type the password to 
resume.

The bug seems to be that the setting in Preferences > Power Management > 
Power > When lid is closed is set to Suspend, but something is getting 
in the way which means that suspension isn't actually happening until 
the lid is opened again. Then it suspends, and has to be woken with the 
Power button before the lock screen can be opened.

The other option in Preferences > Power Management > Power > When lid is 
closed (apart from Shutdown) is Lock Screen, but I assume this means 
leaving everything executing, which is not what you want on a laptop 
with the lid closed.

Certainly sounds related, although I've never had the not-waking problem 
on this (Dell XPS) laptop; but it is definitely something I have had 
happen on a big HP Envy laptop.

The lock screen provides a trivial way to prevent casual, inexpert 
access. This is a first line of defence.

Yes, this point needs to be made repeatedly. People still don't get it.

That's why my machines are all encrypted.

That too, but a lock screen also prevents feline interference :-)
