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 Ubuntu-X, which is subscribed to nvidia-graphics-drivers-390 in Ubuntu. https://bugs.launchpad.net/bugs/1845801 Title: [nvidia] Automatic login fails and then all subsequent logins fail.
