Wayland is not a program, so "Wayland" can't crash. Wayland is only a
protocol for talking to apps that is supported by the Gnome Shell
'eglnative' backend inside the 'mutter' project. This issue is further
confused by the incorrect wording "Ubuntu on Wayland" on the login
screen. Actually it's not running "on Wayland" at all...
That all said, yes the eglnative backend in mutter, which provides
Wayland app support, can crash for its own reasons.
The greeter will default to eglnative ("Wayland") mode, so if you find
disabling that works around the bug (switching to Xorg instead) then
great. However this bug will stay incomplete until we have some sort of
stack trace of a crash, ideally a .crash file.

Bug description:
Here is what I know so far:
After rebooting this morning on Bionic (after receiving the gnome
theme updates, I think), upon reboot the CPU pegs and the greeter is
never displayed (there is a graphics system running, but I'm not sure
what it's doing). My num lock / caps lock keys work, but the touchpad
on the laptop does nothing to the mouse.
If I boot with nomodeset, greeter does not freeze.
Finally, in either case, I am now unable to use my external monitor,
which worked fine before (connected over a USB-C to HDMI dongle).
