Nvidia 390 Installed but Not Loaded

[NoWorries]

I have the graphics drivers install using

sudo add-apt-repository ppa:graphics-drivers

and when I install Nvidia-390, NVIDIA X Server Settings is listed but does not launch.

From a terminal I get the message

:~$ nvidia-settings

ERROR: NVIDIA driver is not loaded

ERROR: Unable to load info from any available system

Does anyone know how to fix this problem?

Fortunately I have an Intel card which works well and I still have a working system.

I was never able to make it go either

Not sure if this is the case here, but often times the pre-releases of *buntu the Nvidia drivers are not ready or do not work at times, often late into the cycle if Nvidia have not released a fully compatible driver for the kernel, or the "shim" that connects the non-free driver to the free kernel is broken . Not sure how the PPA versions are set up, but I will assume this holds true there for the same reasons.

Do the 396 (beta) drivers work, or the 384, as a fallback for the moment? I see the 390 was updated in the past couple of days, and the 396 was added/updates about a day ago.

I am not on 18.04 so I can't say what is up, but in my experience over the years I have seen this happen very often, though less so in recent times. It is why I don't run pre-releases on my desktop/Steam Machine. I would die if I could not finish Metro 2033 all of a sudden

Then again, I don't constantly run my laptops on a semi-permanent pre-release mode anymore since I moved those to Neon.

The 390 is working for me.
Did the nvidia driver and dependencies completely install?

sudo apt -f install
sudo dpkg --configure -a

and if that doesn't show any repairs then load the Nivida module.

Here are the nvidia mods running on my system.

[B]$ lsmod | grep nvidia[/B]
nvidia_uvm            761856  0
nvidia_drm             40960  2
nvidia_modeset       1110016  6 nvidia_drm
nvidia              14344192  741 nvidia_modeset,nvidia_uvm
ipmi_msghandler        49152  1 nvidia

drm                   368640  6 i915,nvidia_drm,drm_kms_helper

Perhaps if you did sudo modprobe nvidia and then

sudo systemctl restart sddm

While I use pre-released candidates, I also am aware that Bionic is now at release candidate and will be released next Thursday. So I think that such problems with the Nvidia card need to be resolved soon.

I did try Nvidia-396 and also Nvidia-384 and all of these failed in the same way as Nvidia-390.

Regarding GG's comments, I hope you are referring to Bionic and not some earlier distribution.

I do not have any problems with my package management, so the first set of commends gave no return. the lsmod | grep nvidia gave the following:

modprobe: ERROR: ../libkmod/libkmod-module.c:832 kmod_module_insert_module() could not find module by name='off'
modprobe: ERROR: could not insert 'off': Unknown symbol in module, or unknown parameter (see dmesg)

This definitely shows that there is something wrong with the Nvidia module.

My apologies. I didn’t notice the Bionic forum header in Tapatalk.

The error msg suggests the error is with lsmod, not NVIDIA.


Can you get a simple listing of mods with lsmod alone?

And does
sudo lsmod | grep i915
give an error?
