Public bug reported:
After a fresh install of the final Ubuntu 18.04 the boot process hangs
after GDM call (the login screen does not appear). After a few tests I
realized that editing /etc/gdm3/custom.conf and removing the comment
before "WaylandEnable=false" make the booting working again (with the
wayland session option not available in GDM). I also tried using
lightdm. In this case the login screen appears and I can choose xorg or
wayland session from there. The latter (wayland) does not work and the
system hangs on a black screen. This is also weird as the wayland
session used to work flawlessly on the very same machine on 17.10. I
don't need the wayland session but just found weird that system cannot
start the login screen out-of-the-box and gdm does not automatically
fallback.
