To continue on my comment #59 ... One user has been impacted on a
physical machine (non-vmware) with the same symptom but can't provide
public details unfortunately, but I witnessed the problem from my own
eye via remote session, and again upgrading to 4.18 kernel did the
trick.

So it really seems like 4.15 is possibly incompatible at some point with
the current mutter package. That is my believe with the level of details
that I know for now and what has been shared to me.

Daniel, any thoughts on this ?
I will try to contact you on irc tonight if we can manage to fight the TZ gap 
between us. ;)

Bug description:
  I'm running Ubuntu 18.04.2 desktop in a virtual machine under VMWare
  Fusion Pro V11.1.0 on MacOS Mojave 10.14.5, all on a 15inch 2018
  Macbook Pro.

  I've been running this Ubuntu 18.04.2 VM without problem for many months 
without problem.
  Yesterday, I did 'sudo apt update; sudo apt upgrade'.  Upon rebooting, the 
system hangs immediately after displaying the splash screen.  I never see a 
login screen.  And I can't use Ctrl+Alt+F2 to navigate to a console/tty login.

  I can SSH into the system however.

  I've found that I can work around the hang/freeze if I uncomment the 
following line in /etc/gdm3/custom.conf;
  #WaylandEnable=false

  After uncommenting the WaylandEnable=false line and rebooting, then I
  see the login prompt as expected and I can then log in and use the
  system normally again.

  After the 'apt upgrade' my system is running linux kernel 4.15.0-51,
  as shown in this 'uname -a' output;

  Linux ubuntuvm1 4.15.0-51-generic #55-Ubuntu SMP Wed May 15 14:27:21
  UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
