Title: Nvidia drivers not working with GeForce GTX 1650 Mobile / Max-Q Status in nvidia-graphics-drivers-440 package in Ubuntu: Confirmed Bug description: *** WORKAROUND AVAILABLE *** See comment 12: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-440/+bug/1871041/comments/12 *** Original Description *** I recently installed Ubuntu 20.04 on a Dell XPS 15, which has a GeForce GTX 1650 Mobile / Max-Q. I installed version 440 because it introduced support for this card: https://www.nvidia.com/download/driverResults.aspx/146189/en-us However, I don't think it's working correctly because if I run nvidia- smi, it cannot communicate with my card. ``` $ nvidia-smi NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running. ``` nvidia-prime is on nvidia, and I rebooted since selecting it. However nvidia-config doesn't display the typical options you find when your nvidia card is active. ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: nvidia-driver-440 440.64-0ubuntu3 ProcVersionSignature: Ubuntu 5.4.0-21.25-generic 5.4.27 Uname: Linux 5.4.0-21-generic x86_64 ApportVersion: 2.20.11-0ubuntu22 Architecture: amd64 CurrentDesktop: GNOME Date: Mon Apr 6 10:58:21 2020 InstallationDate: Installed on 2020-04-03 (2 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Beta amd64 (20200401) SourcePackage: nvidia-graphics-drivers-440 UpgradeStatus: No upgrade log present (probably fresh install) *** Update and likely underlying issue *** Given that the workaround to disable Secure Boot made the driver work, I suspect that the issue is actually that when the drivers are installed and signed (with SB active), then the keys are either not imported correctly or mokmanager was not triggered to be loaded upon next reboot. This causes that even if trying to sign the dkms modules, SB finds them to be untrusted and won't allow the nvidia driver to be loaded.
