NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

Hello, I have a problem with Nvidia driver.
When I run nvidia-smi I get:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the
latest NVIDIA driver is installed and running.

Running nvidia-settings:

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

Currently installed driver, installed via sudo apt install nvidia-driver-430:

dkms status
nvidia, 430.50: added

Running lspci -v | grep 3D gives no output, but I don’t think that is a problem with my graphic card because I do not have any other GPU, nor integrated and my monitor is connected to my GPU and still displays my desktop.

Graphic card: nvidia gtx 1080ti

You’re running a 5.4 kernel on Ubuntu 18.04 and the repo driver is incompatible. Please use the Ubuntu graphics ppa to get the latest driver:

Hello,
I have a similar problem as well. Can you please help or should I go ahead and follow your previous instructions as well.
When I run

nvidia-smi

I get:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the
    latest NVIDIA driver is installed and running.

Running

nvidia-settings

gives

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

Currently installed driver, installed via

sudo apt install nvidia-driver-435

Running

gives no output.

Thank you in advance.

I had a very similar problem and this worked for me:
https://devtalk.nvidia.com/default/topic/1047416/linux/nvidia-driver-is-not-loaded-ubuntu-18-10-/

Yes, I looked at that post and infact, followed #19 of that and updated the kernels. Still nothing. So, I am not sure what I am missing.

Thanks for the reply, though.

Hi, generix, I am encountering similar issue here. When you say “use the Ubuntu graphics ppa to get the latest driver”
Do you mean by sudo ubuntu-drivers autoinstall??

What I have right now:

 Fresh drivers from upstream, currently shipping Nvidia.

## Current Status

Current long-lived branch release: `nvidia-430` (430.40)
Dropped support for Fermi series (https://nvidia.custhelp.com/app/answers/detail/a_id/4656)

Old long-lived branch release: `nvidia-390` (390.129)

For GF1xx GPUs use `nvidia-390` (390.129)
For G8x, G9x and GT2xx GPUs use `nvidia-340` (340.107)
For NV4x and G7x GPUs use `nvidia-304` (304.137) End-Of-Life!

Support timeframes for Unix legacy GPU releases:
https://nvidia.custhelp.com/app/answers/detail/a_id/3142

## What we're working on right now:

- Normal driver updates
- Help Wanted: Mesa Updates for Intel/AMD users, ping us if you want to help do this work, we're shorthanded.

## WARNINGS:

This PPA is currently in testing, you should be experienced with packaging before you dive in here:

Volunteers welcome!

### How you can help:

## Install PTS and benchmark your gear:

    sudo apt-get install phoronix-test-suite

Run the benchmark:

    phoronix-test-suite default-benchmark openarena xonotic tesseract gputest unigine-valley

and then say yes when it asks you to submit your results to openbechmarking.org. Then grab a cup of coffee, it takes a bit for the benchmarks to run. Depending on the version of Ubuntu you're using it might preferable for you to grabs PTS from upstream directly: http://www.phoronix-test-suite.com/?k=downloads

## Share your results with the community:

Post a link to your results (or any other feedback to): https://launchpad.net/~graphics-drivers-testers

Remember to rerun and resubmit the benchmarks after driver upgrades, this will allow us to gather a bunch of data on performance that we can share with everybody.

If you run into old documentation referring to other PPAs, you can help us by consolidating references to this PPA.

If someone wants to go ahead and start prototyping on `software-properties-gtk` on what the GUI should look like, please start hacking!

## Help us Help You!

We use the donation funds to get the developers hardware to test and upload these drivers, please consider donating to the "community" slider on the donation page if you're loving this PPA:

nvidia, 435.21: added

I have rebooted my computer after the reinstallation for several times already. Makes no difference.

And attached my nvidia-bug-report.log
nvidia-bug-report.log.gz (103.3 KB)

Any help would be highly appreciated!
