[Bug 1845801] Re: [nvidia] Automatic login fails and then all subsequent logins fail. Killing gnome-session-binary fixes it, or just not using automatic login.

This bug is definitely triggered by the built kernel image loading the
nvidia drivers. The autologin failures and associated hangs on restarts
can be suppressed as follows...

1) Edit /etc/config/grub to remove 'splash' from GRUB_CMDLINE_LINUX_DEFAULT
2) Regenerate /boot/grub/grub.cfg with 'sudo update-grub'
3) Regenerate the initrd.img files by using 'sudo apt-get --reinstall install' to reinstall the currently installed kernel packages.

After rebooting, the autologin feature in gdm3 can be reselected and on
the next reboot, it will autologin as expected. No loading the nvidia
module through initrd.img also eliminates the hangs on restarting while
autologin is enabled.

I suspect the folks who thought removing splash from grub.cfg didn't
work had failed to rebuild the initrd.img files after regenerating
grub.cfg.

Bug description:
  I just updated to the Ubuntu 19.10 beta. After boot, I'm shown the GDM
  login screen (which I shouldn't; I have auto login enabled), and
  logging in just takes me back to the same user selection screen even
  though the password is correct.

  If I switch to a TTY and run `sudo pkill gnome-session-binary`,
  logging in through GDM starts working again.

  I should add that the do-release-upgrade was rocky; I did it in a
  terminal from within gnome, went away for a while, and when I
  returned, I just saw an Ubuntu 19.10 in a TTY. I was able to do `sudo
  dpkg --configure -a` and complete the upgrade, but I don't know if
  something's still messed up due to that.
