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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1845801 Title: [nvidia] Automatic login fails and then all subsequent logins fail.

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.
