How to add a kernel module

General Linux Question
3

UPDATE:
Duckducking a bit I read:

nvidia-graphics-drivers-340 (340.108-0ubuntu8) hirsute; urgency=medium

Probably a solution:

If you are still looking for an answer, the solution is: ppa:kelebek333/nvidia-legacy

Installing the drivers from PPA, nvidia-updates-340 is available.

So, install the PPA:

sudo add-apt-repository ppa:kelebek333/nvidia-legacy

sudo apt update

next, you need to install the packages:

sudo apt install nvidia-340-updates nvidia-340-updates-dev xorg-modulepath-fix

Then, reboot. You should have the NVidia drivers 340.108 running fine.

Not Ubuntu, but Debian.

lsmod |grep nvi
nvidia_drm             73728  7
drm_kms_helper        278528  1 nvidia_drm
nvidia_modeset       1204224  10 nvidia_drm
nvidia              35389440  404 nvidia_modeset
drm                   626688  11 drm_kms_helper,nvidia,nvidia_drm

I would look for /etc/modprob.d/ whatever conf, if there’s something that may blacklist nvidia driver?
If there is, it is the cause why the driver is not loaded.
If that was an inplace upgrade (according to my readings it was), I can imagine nvidia dirver packages were not correctly upgraded. I’m not a user of Ubuntu, so I can just guess, some process may blacklisted nvidia driver?
However, the time propietary dirver was installed, that surely blakclisted the nouveau driver, so may be this machine took a sit between two chairs? :slight_smile:
Just guessing…
If that was my machine, I’d remove all nvidia related package, something like
apt purge nvidia*
To be sure, I’d take a system snapshot with systemback.sh

Just in case…
After apt purge, I’d look for where the nouveau is blacklisted.
It should be something like /etc/modprobe.d/nvidia-blacklists-nouveau.conf
Reads like this:

cat /etc/modprobe.d/nvidia-blacklists-nouveau.conf
# You need to run "update-initramfs -u" after editing this file.

# see #580894
blacklist nouveau

I’d rename this file, say to nvidia-blacklists-nouveau.conf.bak, so it will be ignored.
I’d issue the update-initramfs -u command, as it is suggested.
Then reboot…
If I’m right, Ubunut should boot up with the nouveau driver…
After that I’d try to reinstall the proprietary drivers, if still needed.
