Ubuntu does not finish boot, crashes loading gdm3

[jlb181]

jbirkhofer@jlb181:~$ lsb_release -rd
Description: Ubuntu 18.04 LTS
Release: 18.04

jbirkhofer@jlb181:~$ apt-cache policy gdm3
gdm3:
  Installed: 3.28.0-0ubuntu1
  Candidate: 3.28.0-0ubuntu1
  Version table:
 *** 3.28.0-0ubuntu1 500
        500 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 Packages
        100 /var/lib/dpkg/status

Boot does not finish, crashes or stops at:

gdm.servicegdm.service
[ OK ] Started Dispatcher daemon for systemd-networkd.
[ OK ] Created slice User Slice of gdm.
       Starting User Manager for UID 120...
[ OK ] Started Session c1 of user gdm.
[ OK ] Started User Manager for UID 120.

And this is where it will sit it goes no further.

I found a fix somewhere that worked.

Edit /etc/gdm3/custom.conf and uncomment 'WaylandEnable=false'

This allowed the boot to finish but I cannont use Firefox to watch streaming from Netflix or Youtube TV. I have to use Chrome but using Chrome cause all kinds of unwanted results on my screen caused by moving the mouse and it is or appears to be totally random.

This is all of the information I have.

After the last update, some kind of codec update Firefox started playing Youtube TV and Netflix. 'WaylandEnable=false' is still uncommented.

Please send us output from these commands:

  lscpu
  lspci -k
  journalctl -b

(This sounds like it might be related to bug 1767606)

Thanks. That confirms this is a duplicate of bug 1727356.
