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;

[Impact]
With most recent version of mutter installed.
If running kernel is in the 4.15 serie (using the vmwgfx video kernel drive) and if the login screen uses wayland, then the login prompt doesn't appears.
All we see is the purple background with ubuntu at the bottom, nothing else.
The vmwgfx driver in kernels prior to 4.17 reported bogus timestamps using the wrong clock. This would lead us to wait forever (or at least 49 years)
before rendering the next frame. There's no decisive way to know this kernel bug is going to happen before it does so just detect timestamps which are obviously going to cause freezes and ignore them.
[Test case]
1) Use Virtualbox or VMware ESxi (if you have the infra)
- [vbox] Make sure in the VM setting that the display uses 'VMSVGA' which will force the OS to pick 'vmwgfx' video kernel driver. (you can confirm with 'lspci -nnvv' command.
2) Deploy a VM with Ubuntu 18.04.1 (which come w/ 4.15)
4) apt-get dist-upgrade
5) Reboot
with 4.15 it will fails
with hwe kernel 4.18 it will work as expected.
[Potential regression]
Low, it should fix vmwgfx and stop using the wrong clock. Sure thing, it can't be worst than current situation where the login doesn't appears at all.

[Impact]
With most recent version of mutter installed.
If running kernel is in the 4.15 serie (using the vmwgfx video kernel driver) and if the login screen uses wayland, then the login prompt doesn't appears. All we see is the purple background with ubuntu in white at the bottom, nothing else.
The vmwgfx driver in kernels prior to 4.17 reported bogus timestamps using the wrong clock. This would lead us to wait forever (or at least 49 years)
before rendering the next frame. There's no decisive way to know this kernel bug is going to happen before it does so just detect timestamps which are obviously going to cause freezes and ignore them.
[Test case]
1) Use Virtualbox or VMware ESxi (if you have the infra)
1.1) [virtualbox] Make sure in the VM setting that the display uses 'VMSVGA' which will force the OS to pick 'vmwgfx' video kernel driver. You can confirm with 'lspci -nnvv' command.
2) Deploy a VM with Ubuntu 18.04.1 (which come w/ 4.15)
4) apt-get dist-upgrade
5) Reboot
with 4.15 it will fails
with hwe kernel 4.18 it will work as expected. # workaround
[Potential regression]
Low, it should fix vmwgfx and stop using the wrong clock. Sure thing, it can't be worse than actual situation where the login doesn't appears at all.

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.

[Impact]
With most recent version of mutter installed.
If running kernel is in the 4.15 serie (using the vmwgfx video kernel driver) and if the login screen uses wayland, then the login prompt doesn't appears. All we see is the purple background with ubuntu in white at the bottom, nothing else.
The vmwgfx driver in kernels prior to 4.17 reported bogus timestamps using the wrong clock. This would lead us to wait forever (or at least 49 years)
before rendering the next frame. There's no decisive way to know this kernel bug is going to happen before it does so just detect timestamps which are obviously going to cause freezes and ignore them.
[Test case]
1) Use Virtualbox or VMware ESxi (if you have the infra)
1.1) [virtualbox] Make sure in the VM setting that the display uses 'VMSVGA' which will force the OS to pick 'vmwgfx' video kernel driver. You can confirm with 'lspci -nnvv' command.
2) Deploy a VM with Ubuntu 18.04.1 (which come w/ 4.15)
4) apt-get dist-upgrade
5) Reboot
with 4.15 it will fails
with hwe kernel 4.18 it will work as expected. # workaround
[Potential regression]
Low, it should fix vmwgfx and stop using the wrong clock.
A test kernel (pre-sru) has been made available to impact users for them to test and conclude it works. It does work as expected, and no regression has been found during the pre-sru testing phase.
It can't be worse than actual situation where the login never appears.

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;
