nvidia proprietary dkms module builds but doesn't load

This is a freshly installed 18.04.3 system.

lspci -vv output for the video card:

purging all nvidia* and libnvidia* packages and rebooting restores operation on Nouveau

[Alberto Milone (albertomilone)]

Hi Steve, it looks like you are using drivers from a PPA (I can tell because the version is 390.129-0ubuntu0~gpu18.04.1), and that, perhaps, the nouveau driver is still loaded (?).

Can you attach the output of "journalctl -S today" and your /var/log/gpu-manager.log after reproducing the problem, please?

[Steve Conklin (sconklin)]

Thanks, Alberto

Yes, I'm using this PPA:
$ cat /etc/apt/sources.list.d/graphics-drivers-ubuntu-ppa-bionic.list
deb http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu bionic main

Attaching the other requested output.

[Alberto Milone (albertomilone)]

For some reason, the nouveau kernel module is being loaded, whereas it should be blacklisted (gpu-manager.log says otherwise, though).

Did you collect the output of "journalctl -S today" after reproducing the problem? (if not, please do)

Also, I noticed that you are using Secureboot. It is another potential source of failure.

[Steve Conklin (sconklin)]

Yes, the output of "journalctl -S today" was attached.

During installation, Secureboot was made a necessity for including non free package repositories.

[Steve Conklin (sconklin)]

Thanks for mentioning Secureboot, I was able to fix the problem.

During installation of 18.04, I selected the option to enable Secureboot, and it enabled "Windows" as the secureboot OS in the BIOS. After I went back into the BOIS config and changed the Secureboot OS to "Other", I was presented with teh dialog to enter the key at boot, and once I did that everything worked.

Feel free to close this or whatever. Thanks!
