You have been subscribed to a public bug: Summary :- Login loop on GDM after installing nvidia drivers using ubuntu-drivers autoinstall sript.
Hardware :- Nvidia GTX 1070 with a Intel Core i7 7700 HQ. HP OMEN 2017 Laptop. Steps to reproduce :- Simply install nvidia drivers using ubuntu-drivers autoinstall script. Expected behaviour :- seamless autologin to desktop, Observed behaviour:- GDM refuses to login automatically and then any attempts of logging in by entering password just simply fail. Hence login loop. Only known mitigation is :- remove the splash from the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" in /etc/default grub and update-grub before installing nvidia drivers, Or chroot into the system after reproducing the error and remove "splash" This bug has been in existence since Ubuntu 19.10, Wanted to ensure this was reported here for resolution. Happy to provide further information if required.
