I'm going to close this since the last response from the original
reporter was a year ago, and it was that the problem could not be
reproduced.
I am still tracking the same upstream bug in Launchpad bug 1814125
though.
If anyone experiences any other issues then please open a new bug by
running:
It was long time ago but IIRC after upgrading from Ubuntu 17.10 to 18.04
GDM would try to start on Wayland. With proprietary Nvidia driver it
would then fallback to software rendering haence the CPU usage.
Disabling Wayland in /etc/gdm/custom.conf or doing clean install fixes
the issue.

Can you confirm the problem is confined to older kernels?
Or more simply, can you please confirm that the problem does not exist
in Ubuntu 18.10? :)

A bit odd that I cannot reproduce this on a fresh 18.04 installation on
the same system.
