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.
