Public bug reported:

After I installed Ubuntu 19.04 (fresh install with hard drive erasing),
I was able to login once just after install. But then after reboot, the
screen freezes in the middle of the boot process and I never get the
login banner.

I was able to launch the recovery mode and get some information through
journalctl command and it seems that the problem is related to a Wayland
server crash. I don't really know if the problem comes from Wayland or
Gnome. The first worrying error message is : "gnome_shell[1165]: Failed
to apply DRM plane transform 0: Permission non accordée" (ie, Permission
denied in french)

Thanks to the recovery mode I was able to upgrade via "apt-get update"
and "apt-get upgrade", but the symptoms were the same after a reboot

I uncommented the "Enable=true" flag of the [debug] section of
/etc/gdm3/custom.conf and I provide and extract of the journalctl output
related to the error as an attachment to this report
(journalctl_extract.txt part). I also provide some system information
(system.txt pat).

I hope this may help to solve the issue.
