Driver installed, but kernel modules not loaded

Graphics / Linux Linux

Hi,

I’ve been struggling with getting the Nvidia drivers to work on my new machine (4 RTX2080Ti GPUs). I tried installing them in various ways on fresh installs of Ubuntu 18.04 (tried the ppa, the .run file and most recently through Lambda Labs’ Stack). Kernel is 4.18.0-15-generic.

Currently, what I have is:

$ 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.

Also, the correct driver seems to have been installed:

$ dpkg -l | grep nvidia

However,

$ lsmod | grep nvidia
$ modprobe nvidia
modprobe: FATAL: Module nvidia not found in directory /lib/modules/4.18.0-15-generic

and nvidia-settings gives

ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system

Any help on this would be appreciated… Only writing here since I’ve basically tried everything out there to no avail.

Thanks!

Looks like you are missing one of these:

linux-headers(-generic), make or build-essential or all of them.

And you kernel module doesn’t get built.

Thanks for the quick response!
As far as I can tell, all three are installed on my system.

Then please upload your nvidia-bug-report

This ended up being an unrelated hardware problem.

Thanks!

Hi, i’m having the exact same problem. can you tell me how you fix it?

I’m not entirely sure how this was resolved - we had additional unrelated issues with this machine, and it was returned to the provider for analysis. Some hardware components were replaced and when it was returned, we did not encounter this issue again.
