I have also opened a ticket here: Bug #1854954 “Black screen on login” : Bugs : nvidia-graphics-drivers-340 package : Ubuntu
I installed Ubuntu from USB with “install third party graphics” enabled and auto login turned off. When the computer restarted, I get the Gnome login screen but after login its just a black screen. Once I get the black screen, the computer is unusable (cannot even open another TTY) and I have to hard reboot the system. However when I get to the login screen I can open TTY2 and then if I sudo apt remove nvidia*
then I can restart and use Nouveau drivers.
I have tried disabling Wayland but if I reinstall the drivers at any point using sudo ubuntu-drivers autoinstall
then I have the same issue again
The output of sudo lspci | grep "VGA"
is:
01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 310] (rev a2)
I am running vanilla GNOME on Xorg. I have also attached the result of nvidia-bug-report.sh
to this post.
